Description

Mehrphasen- Induktivitätenmodul  Multiphase inductance module
Die vorliegende Erfindung betrifft ein Mehrphasen- Induktivitätenmodul, insbesondere für einen Gleichstrom-Spannungswandler, umfassend eine Weichmagnet- Kernstruktur und eine Mehrzahl von Leitern. The present invention relates to a multi-phase inductance module, in particular for a DC-DC converter, comprising a soft magnetic core structure and a plurality of conductors.
Mehrphasen- Induktivitätenmodule der vorstehend genannten Art finden insbesondere Verwendung im Rahmen von Gleichstrom-Spannungswandlern. Einen einschlägigen Stand der Technik bilden insoweit beispielsweise die US 6362986 Bl, die EP 2081287 AI, die WO 2009/037135 AI, die WO 01/75911 AI und die US 2003/0206087 AI. Multiphase inductance modules of the aforementioned type are used in particular in the context of DC voltage transformers. Relevant prior art form in this respect, for example, US Pat. No. 6,326,986 B1, EP 2081287 A1, WO 2009/037135 A1, WO 01/75911 A1 and US 2003/0206087 A1.
Im Lichte des bestehenden Standes der Technik ist die vorliegende Erfindung darauf gerichtet, ein Mehrphasen- Induktivitätenmodul der eingangs angegebenen Art bereitzustellen, dass sich im Sinne einer besonderen Gebrauchstauglichkeit durch eine ausgewogene Kombination praxisrelevanter Vorteile auszeichnet, insbesondere indem es kompakt und zugleich leistungsfähig, kostengünstig herstellbar und zugleich zuverlässig sowie effizient und zugleich tolerant hinsichtlich wechselnder Betriebsbedingungen ist. In the light of the existing state of the art, the present invention is directed to provide a multi-phase inductance module of the type specified that is distinguished in terms of a particular suitability by a balanced combination of practical advantages, in particular by being compact and powerful at the same time, inexpensive to produce and at the same time reliable, efficient and at the same time tolerant of changing operating conditions.
Gelöst wird die vorstehend angegebene Aufgabenstellung durch ein insbesondere für einen Gleichstrom- Spannungswandler geeignetes, eine Weichmagnet- Kernstruktur und eine Mehrzahl von Leitern umfassendes Mehrphasen-Indukti itätenmodul, welches sich durch die nachstehend angegebene Kombination von Merkmalen auszeichnet : The object specified above is achieved by a multi-phase inductance module which is suitable in particular for a DC voltage converter and comprises a soft-magnetic core structure and a plurality of conductors distinguishing between the following characteristics:
Die Kernstruktur umfasst mindestens zwei Kernscheiben, welche im Bereich mindestens einer Trennfläche zusammengefügt sind.  The core structure comprises at least two core disks, which are joined together in the region of at least one separating surface.
Die Leiter sind untereinander identisch ausgeführt und gleichförmig um eine Achse herum angeordnet .  The conductors are identical to each other and uniformly arranged around an axis.
Längs der Trennfläche erstrecken sich Kanäle, welche durch die beiden Kernscheiben begrenzt und in welche die Leiter eingelegt sind.  Along the separation surface extending channels which are bounded by the two core discs and in which the conductors are inserted.
In den von jeweils einem Leiter umschlossenen Bereichen bestehen Zonen mit gegenüber den verbleibenden Zonen des betreffenden Bereiches erhöhter effektiver Spaltdicke.  In the regions enclosed by a conductor there are zones with an increased effective gap thickness compared to the remaining zones of the respective area.
Indem die Kernstruktur mindestens zwei im Bereich einer gemeinsamen, bevorzugt im Wesentlichen ebenen Trennfläche zusammengefügte Kernscheiben umfasst, wobei sich längs jener Trennfläche Kanäle erstrecken, in welche die Leiter eingelegt sind, lassen sich erfindungsgemäße Mehrphasen-Induktivitätenmodule mit einem vergleichweise geringen Herstellungsaufwand fertigen. Dazu trägt insbesondere bei, dass - vor dem Zusammenfügen der beiden Kernscheiben - in die besagten Kanäle vorgefertigte Leiter eingelegt werden können, d.h. die Leiter nicht individuell auf Vorsprüngen der Kernstruktur gewickelt oder auf sonstige Weise geformt werden müssen. Zu besonders geringen Herstellungskosten vermag dabei weiterhin beizutragen, dass sämtliche Leiter untereinander identisch ausgeführt sind. Durch die gleichförmige Anordnung der einzelnen Leiter um eine Achse herum - und somit auch der von den einzelnen Leitern umgrenzten Bereiche - ergibt sich eine ideale Symmetrie auch der elektrischen bzw. magnetischen Eigenschaften der einzelnen Phasen, was sich in einer besonders homogenen, gleichförmigen Spannungswandlung niederschlägt . Zu den hervorragenden Leistungsdaten des erfindungsgemäßen Mehrphasen- Induktivitätenmoduls trägt weiterhin bei, dass jeder jener Bereiche, die von jeweils einem Leiter umschlossen bzw. begrenzt sind, im Bereich der Trennfläche Zonen aufweist, welche gegenüber den verbleibenden Zonen des betreffenden Bereichs eine erhöhte effektive Spaltdicke aufweisen. Dies verhindert eine magnetische Sättigung des induktive Effekte nutzenden Gesamtsystems, was hinwiederum erlaubt, dass ein mit dem erfindungsgemäßen Mehrphasen- Induktivitätenmodul ausgestatteter Gleichstrom-Spannungswandler hochdynamisch auf abrupte Änderungen der Eingangsspannung reagiert. Die erfindungsgemäß ausgeführte Kombination der Weichmagnet-Kernstruktur und der darin - in die betreffenden Kanäle - eingebetteten Leiter gewährleistet im Sinne optimaler Betriebseigenschaften sowohl den (ausgeprägten) magnetischen Anschluss benachbarter Leiter untereinander als auch, in reduziertem Umfang, den magnetischen Anschluss (die magnetische Koppelung) sämtlicher Leiter untereinander sowie einen bestimmten magnetischen Anschluss um jeden einzelnen, individuellen Leiter. All die vorstehend dargelegten hervorragenden technischen, funktionellen sowie wirtschaftlichen Vorteile lassen sich im übrigen, was einen weiteren bedeutenden Vorteil der vorliegenden Erfindung darstellt, bei einem besonders kompakten Mehrphasen- Induktivitätenmodul realisieren. By virtue of the fact that the core structure comprises at least two core disks joined together in the region of a common, preferably substantially planar parting surface, channels extending along the parting surface into which the conductors are inserted, multiphase inductance modules according to the invention can be manufactured with a comparatively low production outlay. Contributes in particular to the fact that - before the joining of the two core disks - prefabricated conductors can be inserted into said channels, ie the conductors do not have to be individually wound on projections of the core structure or formed in any other way. At particularly low production costs can continue to contribute that all conductors with each other are made identical. Due to the uniform arrangement of the individual conductors around an axis - and thus also the areas delimited by the individual conductors - an ideal symmetry also results for the electrical or magnetic properties of the individual phases, which is reflected in a particularly homogeneous, uniform voltage transformation. The outstanding performance data of the multiphase inductance module according to the invention further contributes to the fact that each of those regions, which are enclosed by a respective conductor, has zones in the region of the separation surface which have an increased effective gap thickness compared to the remaining zones of the relevant region. This prevents magnetic saturation of the overall system using inductive effects, which in turn allows a DC-DC converter equipped with the polyphase inductance module according to the invention to react highly dynamically to abrupt changes in the input voltage. The inventively executed combination of soft magnetic core structure and therein - in the respective channels - embedded conductor ensures optimal operating characteristics both the (pronounced) magnetic connection of adjacent conductors with each other and, to a reduced extent, the magnetic connection (the magnetic coupling) all Conductors with each other and a specific magnetic connection around each individual, individual conductor. All the outstanding technical, functional and economic points outlined above Incidentally, advantages can be realized in a particularly compact multiphase inductance module, which represents another significant advantage of the present invention.
Herstellungstechnisch ist es besonders einfach, wenn die zwischen den beiden Kernscheiben bestehende Trennfläche eben ist, wobei die Achse des Induktivitätenmoduls zweckmäßigerweise auf der Trennebene, d.h. der Ebene der Trennfläche senkrecht steht. Dabei verlaufen die Leiter besonders bevorzugt zumindest abschnittsweise parallel nicht nur jeweils zueinander sondern auch zur Trennebene. Ein vergleichsweise einfacher Aufbau mit geringem Herstellungsaufwand und einer einfachen Montage sind die sich hieraus ergebenden Vorteile. In terms of manufacturing technology, it is particularly simple if the separating surface existing between the two core disks is flat, with the axis of the inductance module expediently being at the parting plane, i. the plane of the separating surface is vertical. In this case, the conductors are particularly preferably at least partially parallel not only to each other but also to the parting plane. A comparatively simple structure with low production costs and a simple assembly are the resulting advantages.
Zwingend sind diese Gestaltungsmerkmale indessen nicht. However, these design features are not mandatory.
Gemäß einer ersten bevorzugten Weiterbildung der Erfindung verlaufen in jedem Kanal zueinander parallele Abschnitte zweier einander benachbarter Leiter. Beim Betrieb des Mehrphasen-Induktivitätenmoduls im Rahmen eines Gleichstrom-Spannungswandlers sind die betreffenden, in jeweils einem Kanal parallel zueinander verlaufenden Abschnitte der beiden jeweils einander According to a first preferred development of the invention, mutually parallel sections of two mutually adjacent conductors run in each channel. During operation of the multiphase inductance module in the context of a DC-DC voltage converter, the respective sections of the two, which run parallel to one another in each case, are each one another
benachbarten Leiter typischerweise in entgegengesetzter Richtung stromdurchflossen . Die beiden jeweils betreffenden Leiter sind, mit anderen Worten, über ihre parallel zueinander im selben Kanal der Weichmagnet- Kernstruktur verlaufenden Abschnitte induktiv miteinander gekoppelt. Auch dies ist ein Merkmal, was sich po- sitiv auf das Betriebsverhalten eines mit dem Mehrphasen-Induktivitätenmodul ausgestattetem Gleichstrom- Spannungswandlers auswirkt . adjacent conductors are typically current-flowed in the opposite direction. In other words, the two respective conductors are inductively coupled to one another via their sections running parallel to one another in the same channel of the soft magnetic core structure. This too is a characteristic of what has a positive effect on the performance of a DC-DC converter equipped with the polyphase inductance module.
Gemäß einer anderen bevorzugten Weiterbildung der Erfindung umfasst das Mehrphasen-Induktivitätenmodul, d.h. dessen Weichmagnet-Kernstruktur, zwei identisch ausgeführte und spiegelbildlich zueinander angeordnete Kernscheiben. Bei dieser Weiterbildung weisen somit beide Kernscheiben angrenzend an die gemeinsame Trennfläche jeweils die Kanäle bildende Nuten auf. Besonders vorteilhaft ist es dabei, wenn die an die Trennfläche angrenzenden Nuten der beiden Kernscheiben einander - zur Bildung eines gemeinsamen Kanals - teilweise überlappen, was sich gemäß einer weiterhin bevorzugten Weiterbildung vorteilhafter Weise dadurch erreichen lässt, dass die Nuten jeweils um eine gegenüber ihrer halben Breite geringeres Maß relativ zu einem zugeordneten Radius versetzt sind. Eine solche teilweise Überlappung der beiden jeweils einen gemeinsamen Kanal begrenzenden Nuten geht Hand in Hand mit einem entsprechenden Versatz der beiden in die betreffenden Nuten eingelegten Abschnitte der betreffenden Leiter in Umfangsrichtung, was sich besonders günstige auf das in der Kernstruktur induzierte Magnetfeld auswirkt. According to another preferred embodiment of the invention, the multiphase inductance module, i. its soft magnetic core structure, two identically designed and mirror images of each other arranged core discs. In this development, therefore, both core disks have adjacent to the common separation surface in each case the channels forming grooves. It is particularly advantageous in this case if the grooves of the two core disks adjoining the separating surface partially overlap one another to form a common channel, which according to a further preferred development can advantageously be achieved in that the grooves are each one opposite their half width smaller amount are offset relative to an associated radius. Such a partial overlap of the two respective common channel defining grooves goes hand in hand with a corresponding offset of the two inserted into the respective grooves sections of the respective conductors in the circumferential direction, which has a particularly favorable effect on the magnetic field induced in the core structure.
Zwingend ist der vorstehend erläuterte Versatz von jeweils zwei Nuten, welche gemeinsam einen Kanal definieren und begrenzen, indessen nicht. Im Rahmen der vorliegenden Erfindung können die besagten, in beiden Kernscheiben ausgeführten Nuten einander vielmehr auch vollständig überlappen, insbesondere indem sie sich - bei zwei identisch gestalteten Kernscheiben - exakt längs eines jeweils zugeordneten Radius' erstrecken. However, the above explained offset of two grooves, which together define and limit a channel, is imperative. In the context of the present invention, the said, in both Core grooves running grooves rather completely overlap each other, in particular by - with two identically designed core discs - exactly along a respective associated radius' extend.
Wenngleich eine identische Ausführung der beiden Kernscheiben unter Aspekten der Herstellungskosten günstig ist, so ist sie indessen keineswegs zwingend. Vielmehr kann die Weichmagnet-Kernstruktur auch aus zwei unterschiedlichen Kernscheiben zusammengefügt sein, namentlich dergestalt, dass nur eine der beiden Kernscheiben angrenzend an die gemeinsame Trennfläche Nuten aufweist. Im Hinblick auf eine gute Leistungscharakteristik ist dabei besonders vorteilhaft, wenn in den Nuten bzw. Kanälen zwischen den beiden jeweils darin aufgenommenen Leitern bzw. Leiterabschnitten Stege aus weichmagnetischem Material angeordnet sind, so dass die Leiterabschnitte nicht unmittelbar aneinander anliegen. Solche Stege können dabei integraler Bestandteil einer der beiden Kernscheiben sein. Es kann sich bei ihnen indessen auch um separate Teile handeln, welche zwischen den beiden Leiterabschnitten eingelegt werden. Entsprechendes gilt im Übrigen auch bei der weiter oben erläuterten Weiterbildung, bei welcher beide Kernscheiben angrenzend an die Trennfläche sich radial erstreckende, einander vollständig überlappende Nuten Although an identical design of the two core disks is favorable in terms of manufacturing costs, it is by no means mandatory. Rather, the soft magnetic core structure can also be assembled from two different core disks, namely such that only one of the two core disks has grooves adjacent to the common separation surface. With regard to a good performance characteristic, it is particularly advantageous if webs of soft magnetic material are arranged in the grooves or channels between the two conductors or conductor sections accommodated therein so that the conductor sections do not rest directly against one another. Such webs can be an integral part of one of the two core disks. However, they can also be separate parts, which are inserted between the two conductor sections. The same applies, moreover, also in the development explained above, in which both core disks are adjacent to the parting surface radially extending, completely overlapping each other grooves
aufweisen, welche gemeinsam den jeweiligen Kanal begrenzen . Die Höhe der vorstehend beschriebenen Stege ist zweckmäßigerweise geringer als die entsprechende Erstreckung der Nut bzw. des Kanals, sodass zwischen dem Steg und mindestens einer der beiden Kernscheiben ein Luftspalt verbleibt. Dies kommt der Leistungscharakteristik insbesondere bei dynamischen Vorgängen zugute. have, which together limit the respective channel. The height of the webs described above is expediently less than the corresponding extension of the groove or of the channel, so that an air gap remains between the web and at least one of the two core disks. This benefits the performance characteristics, especially in dynamic processes.
Zur Bereitstellung der weiter oben erläuterten Zonen erhöhter effektiver Spaltdicke zwischen den beiden zur Weichmagnet-Kernstruktur zusammengefügten Kernscheiben sind an mindestens einer der beiden Kernscheiben angrenzend an die Trennfläche, bevorzugt zentrumsnah benachbart zu der Achse Vertiefungen ausgeführt. Die räumliche Erstreckung jener Vertiefungen definiert dabei jeweils jene Zone, innerhalb derer in dem von den jeweils zugeordneten Leiter umschlossenen Bereich die effektive Spaltdicke gegenüber den verbleibenden Zonen des betreffenden Bereiches erhöht ist. In order to provide the zones of increased effective gap thickness explained above between the two core disks joined together to form the soft magnetic core structure, recesses are provided on at least one of the two core disks adjacent to the parting surface, preferably close to the center adjacent to the axis. The spatial extension of those recesses defines in each case that zone within which the effective gap thickness is increased in the region enclosed by the respective associated conductor with respect to the remaining zones of the relevant region.
Eine wiederum andere bevorzugte Weiterbildung der vorliegenden Erfindung zeichnet sich dadurch aus, dass mindestens eine der Kernscheiben einen zentralen Durchbruch aufweist, in welchen die Kanäle münden. In dem betreffenden Durchbruch sind jeweils die beiden Abschnitte eines jeden Leiters, welche mit zugeordneten Abschnitten der beiden benachbarten Leiter parallel zueinander in gemeinsamen Kanälen verlaufen, über einen gebogenen Verbindungsabschnitt miteinander verbunden. Der zentrale Durchbruch wirkt sich dabei nicht nur, indem er das Einlegen vorgefertigter Leiter in die Kernscheibe (n) erleichtert, günstig aus im Hinblick auf eine einfache, kostengünstige Herstellung des erfindungsgemäßen Mehrphasen- Induktivitätenmoduls ; vielmehr ist er auch von Vorteil im Hinblick auf eine günstige Leistungscharakteristik des Induktivitätenmoduls. Yet another preferred development of the present invention is characterized in that at least one of the core disks has a central opening in which the channels open. In the respective breakthrough, the two sections of each conductor, which run with associated sections of the two adjacent conductors parallel to each other in common channels, are connected to each other via a curved connecting portion. The central breakthrough does not just affect this by placing prefabricated ladder in the Core disc (s) facilitates, favorable from in view of a simple, inexpensive production of the multiphase inductance module according to the invention; rather, it is also advantageous with regard to a favorable performance characteristic of the inductance module.
Gemäß einer wiederum anderen bevorzugten Weiterbildung der vorliegenden Erfindung umschlingen die Leiter eine jeweils zwischen zwei benachbarten Kanälen verbleibende Erhebung der betreffenden Kernscheibe nur zu weniger als 360°, d.h. es liegt besonders bevorzugt jeweils nur eine unvollständige Umschlingung der betreffenden Erhebung durch den jeweils zugeordneten Leiter vor. Insbesondere haben sich trotz ihres vergleichsweise According to yet another preferred development of the present invention, the conductors wrap around each of two adjacent channels remaining elevation of the relevant core disk only to less than 360 °, i. It is particularly preferred in each case only an incomplete wrap the respective survey by the respective associated conductor before. In particular, despite their comparatively
einfachen Aufbaus erfindungsgemäße Induktivitätenmodule als besonders leistungsfähig erwiesen, bei denen jeder der Leiter eine zugeordnete Erhebung der betreffenden Kernscheibe nur zu etwa zwei Drittel umschlingt. Diese Weiterbildung der Erfindung kommt somit mit vergleichsweise kurzen Leitern aus, was sich in entsprechend geringen Verlusten wie auch entsprechend geringen simple construction inductance modules according to the invention proved to be particularly efficient, in which each of the conductors wraps around an associated survey of the relevant core disk only about two-thirds. This development of the invention thus comes with relatively short conductors, resulting in correspondingly low losses as well as correspondingly low
Herstellungskosten niederschlägt, wobei diese Bauweise auch einer einfachen, kostengünstigen Fertigung entgegen kommt, weil vorgefertigte Leiter besonders einfach in die entsprechenden Nuten der Kernscheibe (n) eingelegt werden können. Reduces manufacturing costs, this design is also a simple, inexpensive production counter, because prefabricated ladder can be particularly easily inserted into the corresponding grooves of the core disc (s).
Besonders bevorzugt weisen die Leiter jeweils radial außen mindestens einen individuellen Anschluss auf, an dem sie kontaktiert werden. Je nach der spezifischen Verwendung des Mehrphasen-Induktivitätenmoduls können die Leiter radial außen auch zwei individuell kontak- tierbare Anschlüsse aufweisen. Gemäß einer anderen bevorzugten Weiterbildung sind die Leiter mit jeweils einem ihrer Enden mit einem gemeinsamen Anschluss kontaktiert. In dem zuletzt genannten Fall ist es besonders günstig, wenn der gemeinsame Anschluss einen um die Achse herum angeordneten Anschlussring umfasst, an welchen jeder der Leiter mit jeweils einem seiner Enden kontaktiert ist. Particularly preferably, the conductors each have at least one individual connection radially outward, at which they are contacted. Depending on the specific Using the multiphase inductance module, the conductors can also have two individually contactable connections radially on the outside. According to another preferred development, the conductors are each contacted with one of their ends to a common terminal. In the latter case, it is particularly favorable if the common connection comprises a connecting ring arranged around the axis, to which each of the conductors is in each case contacted by one of its ends.
Eine wiederum andere bevorzugte Weiterbildung der Erfindung zeichnet sich dadurch aus, dass die beiden Kernscheiben im Bereich der Trennfläche miteinander verklebt sind. Eine solche Form des dauerhaften Zusammenfügens der beiden Kernscheiben führt bei geringen Herstellungskosten zu einem langlebigen, dauerhaft zuverlässigen Induktivitätenmodul. Im Hinblick auf die Leistungscharakteristik, insbesondere bei dynamischen Vorgängen, ist es dabei besonders günstig, wenn - zur Bereitstellung einer Mindestspaltdicke zwischen den beiden Kernscheiben - in den Klebstoff Partikel eingebettet sind. Yet another preferred development of the invention is characterized in that the two core disks are glued together in the region of the separating surface. Such a form of permanent assembly of the two core disks results in low production costs to a long-lasting, permanently reliable inductance module. With regard to the performance characteristics, in particular in dynamic processes, it is particularly advantageous if - to provide a minimum gap thickness between the two core disks - are embedded in the adhesive particles.
Als Material für die Weichmagnet-Kernstruktur kommt insbesondere gesintertes Ferrit in Betracht. Indessen lässt sich die vorliegende Erfindung ersichtlich auch unter Verwendung anderer weichmagnetischer Materialen umsetzen . Obgleich vorstehend die vorliegende Erfindung erläutert wurde anhand von Mehrphasen-Induktivitätenmodulen, bei denen die Weichmagnet-Kernstruktur aus zwei zusammengefügten Kernscheiben besteht, so ist darauf hinzuweisen, dass dies nicht zwingend ist. Vielmehr lässt sich die vorliegende Erfindung auch bei komplexer aufgebauten Induktivitätenmodulen anwenden, insbesondere bei solchen, bei denen die Kernstruktur drei geschichtete, bevorzugt in zwei zueinander parallelen Trennebenen zusammengefügte Kernscheiben umfasst. Bei einer solchen Ausgestaltung können insbesondere die beiden äußeren Kernscheiben identisch ausgeführt und spiegelbildlich zueinander angeordnet sein und zwischen sich eine Zwischenscheibe aufnehmen. Kanäle, in welchen Abschnitte der Leiter aufgenommen sind, die sich parallel erstrecken zu Abschnitten der jeweils benachbarten Leiter, können dabei - je nach den angestrebten Eigenschaften des Induktivitätenmoduls - im Bereich einer der beiden Trennflächen vorgesehen sein oder aber im Bereich beider Trennflächen. As a material for the soft magnetic core structure is in particular sintered ferrite into consideration. However, the present invention can also be realized using other soft magnetic materials. Although the present invention has been explained above with reference to multiphase inductance modules in which the soft magnetic core structure consists of two joined core disks, it should be noted that this is not mandatory. On the contrary, the present invention can also be applied to more complex inductance modules, in particular those in which the core structure comprises three layered core disks, which are preferably joined together in two mutually parallel parting planes. In such a configuration, in particular the two outer core disks can be made identical and arranged in mirror image to each other and record between them an intermediate disc. Channels, in which sections of the conductors are accommodated, which extend parallel to sections of the respectively adjacent conductors, can be provided in the region of one of the two separating surfaces or, depending on the desired properties of the inductance module, or in the area of both separating surfaces.
Im Folgenden wird die vorliegende Erfindung anhand von vier in der Zeichnung veranschaulichten bevorzugten Ausführungsbeispielen näher erläutert. Dabei zeigt Fig. 1 in perspektivischer Ansicht eine erste Aus- führungsform eines nach der vorliegenden Erfindung ausgeführten Mehrphasen- Induktivitätenmoduls , In the following, the present invention is explained in more detail with reference to four preferred embodiments illustrated in the drawing. 1 is a perspective view of a first embodiment of a multiphase inductance module according to the present invention;

Das in den Fig. 1 bis 5 veranschaulichte, zur Verwendung im Rahmen eines Gleichstrom-Spannungswandlers bestimmte und geeignete Mehrphasen- Induktivitätenmodul 1 umfasst eine Weichmagnet-Kernstruktur 2 und sechs Leiter 3. Die Kernstruktur ist dabei aus zwei Kernscheiben, nämlich einer unteren Kernscheibe 4 und einer oberen Kernscheibe 5 zusammengefügt. Die Begriffe "obere Kernscheibe" und "untere Kernscheibe" dienen dabei vorliegend allein der Unterscheidung für die Zwecke der nachstehenden Erläuterung; denn technisch-strukturell sind beide Kernscheiben, wie im folgenden näher erkennbar wird, identisch. Zur Bildung der Kernstruktur 2 sind die beiden Kernscheiben 4 und 5, spiegelbildlich zueinander angeordnet, im Bereich einer ebenen gemeinsamen Trennfläche 6 miteinander verklebt. The multi-phase inductance module 1, which is illustrated in FIGS. 1 to 5 and is intended for use as part of a DC voltage converter, comprises a soft-magnetic core structure 2 and six conductors 3. The core structure is composed of two core disks, namely a lower core disk 4 and an upper core disc 5 joined together. The terms "upper core disk" and "lower core disk" are used here in the present case, only the distinction for the purposes of the following explanation; technically and structurally, both core disks are identical, as will be seen in more detail below. To form the core structure 2, the two core disks 4 and 5, arranged in mirror image to each other, glued together in the region of a flat common separation surface 6.
Längs der Trennfläche 6 erstrecken sich sechs im Wesentlichen radial zu einer Achse 7 der Kernstruktur 2 ausgerichtet Kanäle 8, welche durch die beiden Kernscheiben 4 und 5 begrenzt sind. Jeder der Kanäle 8, die sich radial außen zur äußeren Umfangsfläche 9 der Kernstruktur 2 und radial innen zu einem darin angeordneten zentralen Durchbruch 10 hin öffnen, ist dabei definiert durch jeweils zwei in den beiden Kernscheiben 4 und 5 angeordnete, angrenzend an die Trennfläche 6 ausgeführte Nuten, d.h. eine in der unteren Kernscheibe 4 angeordnete Nut 11 und eine in der oberen Kernscheibe 5 angeordnete Nut 12. Bei jedem der Kanäle 8 überlappen die beiden betreffenden Nuten 11 und 12 einander teilweise. Hierzu sind Nuten 11 und 12 an der jeweiligen Kernscheibe 4 bzw. 5 nicht exakt radial ausgerichtet, sondern vielmehr und um ein gegenüber ihrer halben Breite B geringeres Maß relativ zu einem zugeordneten Radius R versetzt. Along the dividing surface 6 extend six substantially aligned radially to an axis 7 of the core structure 2 channels 8, which are bounded by the two core disks 4 and 5. Each of the channels 8, which open radially outward to the outer circumferential surface 9 of the core structure 2 and radially inwardly toward a central aperture 10 disposed therein, is defined by two each in the two core disks 4 and 5, adjacent to the separation surface 6 executed Grooves, ie a groove 11 disposed in the lower core disk 4 and a groove 12 disposed in the upper core disk 5. In each of the channels 8, the two respective grooves 11 and 12 partially overlap each other. For this purpose, grooves 11 and 12 are not exactly aligned radially on the respective core disk 4 or 5, but rather are offset relative to an associated radius R by a smaller amount relative to their half width B.
Die sechs in die Kernstruktur 2 eingelegten Leiter 3 sind untereinander identisch ausgeführt und gleichförmig um die Achse 7 herum angeordnet. Jeder Leiter 3 weist zwei gerade Abschnitte 13 auf, die einen Winkel von etwa 60° miteinander einschließen und über einen Verbindungsbogen 14 miteinander verbunden sind. Endsei- tig laufen die Leiter 3 in jeweils zwei Anschlussabschnitte 15 aus, die sich durch entsprechende Kröpfung und Biegung der Leiter 3 im Wesentlichen parallel zur Achse 7 erstrecken. Die sechs Leiter 3 sind dergestalt in die Kanäle 8 der Kernstruktur 2 eingelegt, dass in jedem Kanal 8 zueinander parallel gerade Abschnitte 13 zweier einander benachbarter Leiter 3 verlaufen. Die Verbindungsbogen 14 verlaufen dabei in dem zentralen Durchbruch 10 der Kernstruktur 2. The six inserted into the core structure 2 conductors 3 are identical to each other and arranged uniformly about the axis 7 around. Each conductor 3 has two straight sections 13, which enclose an angle of about 60 ° with each other and are connected to each other via a connecting sheet 14. On the end side, the conductors 3 terminate in respectively two connection sections 15, which extend essentially parallel to the axis 7 by corresponding bending and bending of the conductors 3. The six conductors 3 are inserted into the channels 8 of the core structure 2 in such a way that straight sections 13 of two mutually adjacent conductors 3 run parallel to one another in each channel 8. The connecting sheets 14 extend in the central opening 10 of the core structure 2.
Durch die Nuten 11 und 12 sind an der jeweiligen Kernscheibe 4 bzw. 5 sechs Erhebungen 16 definiert, nämlich als die jeweils zwischen zwei einander benachbarten Nuten 11 bzw. 12 bestehenden und durch diese begrenzten Bereiche B. Wie Fig. 2 veranschaulicht umschlingt jeder Leiter 3 eine solche jeweils zwischen zwei benachbarten Kanälen 11 bzw. 12 verbleibende Erhebung 16 nur zu weniger als 360°. Radial außen, benachbart zu der äußeren Umfangsfläche 9 der Kernstruktur besteht zwischen den beiden Anschlussabschnitten 15 ein Abstand X, auf dem die jeweilige Erhebung 16 nicht von dem zugeordneten Leiter 3 umschlungen ist. Im Bereich der Kröpfung und Biegung der Leiter 3 bestehen sich in Umfangsrichtung erstreckende Übergangsabschnitte 17, durch welche sich die beiden Schenkel jedes Leiters 3 einander zwischen den äußeren Enden der beiden geraden Abschnitte 13 und den beiden Anschlussabschnitten 15 auf den verbleibenden Abstand X annähern. By means of the grooves 11 and 12, six elevations 16 are defined on the respective core disk 4 or 5, namely as the areas B respectively existing between two adjacent grooves 11 and 12 and bounded by these. As illustrated in FIG. 2, each conductor 3 wraps around such each remaining between two adjacent channels 11 and 12 survey 16 only less than 360 °. Radially outside, adjacent to the outer peripheral surface 9 of the core structure, there is a distance X between the two connection sections 15, on which the respective elevation 16 is not looped around by the associated conductor 3. In the region of the bend and bend of the conductor 3 are circumferentially extending transition portions 17, through which the two legs of each conductor 3 between the outer ends of the two straight portions 13 and approximate the two connection sections 15 to the remaining distance X.
Wie dies insbesondere der Fig. 2 entnehmbar ist, sind an der unteren Kernscheibe 4 - das Gleiche gilt auch für die obere Kernscheibe 5 - angrenzend an die Trennfläche 6 Vertiefungen V ausgeführt, und zwar zentrumsnah benachbart zu der Achse 7. Auf diese Weise besteht - bei der aus den beiden Kernscheiben 4 und 5 zusammengefügten Kernstruktur 2 - im Bereich der Trennfläche 6 jeweils in dem von einem Leiter 3 umschlossenen Bereich B (radial innen) eine Zone ZI mit gegenüber der As can be seen in particular from FIG. 2, depressions V are formed on the lower core disk 4-the same also applies to the upper core disk 5-adjacent to the separating surface 6, and close to the center adjacent to the axis 7. In this way, in the case of the core structure 2 joined together from the two core disks 4 and 5 - in the area of the separating surface 6 in each case in the area B (radially inward) enclosed by a conductor 3, a zone ZI with respect to FIG
verbleibenden Zone Z2 des betreffenden Bereiches B erhöhter effektiver Spaltdicke zwischen den beiden Kernscheiben. Der Einfluss der Ausführung der Kanäle 8 durch teilweise Überlappung der beiden jeweiligen Nuten 11 und 12 auf das sich bei (entgegengesetzter) Durchströmung der beiden Leiter 3 ergebende Magnetfeld ist durch die beiden Feldlinien F symbolisiert. remaining zone Z2 of the relevant area B increased effective gap thickness between the two core disks. The influence of the execution of the channels 8 by partial overlapping of the two respective grooves 11 and 12 on the (opposite) flow through the two conductors 3 resulting magnetic field is symbolized by the two field lines F.
Die Figuren 6 und 7 veranschaulichen zwei die Ausführung der Kanäle betreffende Abwandlungen des vorstehend erläuterten Mehrphasen- Induktivitätenmoduls nach den Fig. 1 bis 5. Nach Fig. 6 sind, zur Bildung der Kanäle 8.1, nur in der unteren Kernscheibe 4.1 - angrenzend an die zwischen dieser und der oberen Kernscheibe 5.1 bestehende Trennfläche 6.1 - Nuten 11.1 ausgeführt. Die obere Kernscheibe 5.1 ist demgegenüber im Bereich der Trennfläche 6.1 plan. Wiederum sind aber in jedem Kanal 8.1 zueinander parallel erstreckende gerade Abschnitte 13.1 zweier einander benachbarter Leiter 3.1 aufgenommen, wobei in den Nuten 11.1 bzw. den Kanälen 8.1 zwischen den beiden jeweils darin aufgenommenen Figures 6 and 7 illustrate two variations of the execution of the channels of the above-discussed multi-phase inductance module according to FIGS. 1 to 5. According to Fig. 6, to form the channels 8.1, only in the lower core disk 4.1 - adjacent to the between this and the upper core disc 5.1 existing separation surface 6.1 - grooves 11.1 executed. By contrast, the upper core disk 5.1 is flat in the area of the separating surface 6.1. Again, however, in each channel 8.1 are mutually parallel extending straight sections 13.1 of two adjacent conductors 3.1 recorded, wherein in the grooves 11.1 and the channels 8.1 between the two each received therein
Leiterabschnitten 13.1 Stege 18 aus weichmagnetischem Material angeordnet sind. Die (parallel zur Achse 7 bestimmte) Höhe h der Stege 18 ist dabei geringer als die lichte Höhe H der Kanäle 8.1, so dass zwischen dem Steg 18 und der oberen Kernscheibe 5.1 ein axialer Spalt 19 verbleibt. Conductor sections 13.1 webs 18 are arranged made of soft magnetic material. The (height determined parallel to the axis 7) h of the webs 18 is less than the clear height H of the channels 8.1, so that between the web 18 and the upper core disk 5.1 an axial gap 19 remains.
Nach Fig. 7 sind, zur Bildung der Kanäle 8.2, sowohl in der unteren Kernscheibe 4.2 als auch in der oberen Kernscheibe 5.2 - angrenzend an die zwischen diesen bestehende Trennfläche 6.2 - Nuten 11.2 bzw. 12.2 ausgeführt. Die jeweils einen Kanal 8.2 definierenden Nuten 11.2 und 12.2 sind von gleicher Breite, erstrecken sich radial und überlappen einander vollständig. In den Nuten 11.2 der unteren Kernscheibe 4.2 sind jeweils zwischen den beiden darin aufgenommenen Leiterabschnitten 13.2 an die untere Kernscheibe 4.2 angeformte Stege 20 aus weichmagnetischem Material angeordnet. Die (parallel zur Achse 7 bestimmte) Höhe der Stege 19 ist dabei wiederum geringer als die lichte Höhe der Kanäle 8.2, so dass zwischen dem Steg 20 und der oberen Kernscheibe 5.2 ein axialer Spalt 21 verbleibt. According to FIG. 7, in order to form the channels 8.2, both in the lower core disk 4.2 and in the upper core disk 5.2, grooves 11.2 and 12.2 are formed adjacent to the separating surface 6.2 therebetween. Each of a channel 8.2 defining grooves 11.2 and 12.2 are of equal width, extend radially and overlap each other completely. In the grooves 11.2 of the lower core disk 4.2 are each formed between the two therein recorded conductor sections 13.2 to the lower core disk 4.2 molded webs 20 of soft magnetic material. The (parallel to the axis 7 certain) height of the webs 19 is again less than the clear height of the channels 8.2, so that between the web 20 and the upper core disk 5.2 an axial gap 21 remains.
Während bei dem in den Fig. 1 bis 5 veranschaulichten, vorstehend erläuterten Mehrphasen- Induktivitätenmodul jeder Leiter 3 zwei - durch die Anschlussabschnitte 15 gebildete - individuelle Anschlüsse 22 aufweist, sind bei dem in den Fig. 8 und 9 gezeigten Mehrphasen- Induktivitätenmodul die Leiter 3.3 mit jeweils einem ihrer beiden Enden mit einem gemeinsamen Anschluss 23 kontaktiert. Dieser umfasst einen um die Achse 7.3 herum angeordneten Anschlussring 24 und eine daran angeordnete Anschlussfahne 25. Der Anschlussring 24 ist etwa auf Höhe der oberen Kernscheibe 5.3 angeordnet. Die mit ihm verbundenen Enden 26 der Leiter 3.3 sind demgemäß, abweichend von dem Ausführungsbeispiel nach den Fig. 1 bis 5, nach oben gebogen, d.h. in die zu den individuellen Anschlüssen 22.3 entgegengesetzte Richtung. Die Anschlussfahne 25 ist parallel zur Achse 7.3 nach unten gerichtet, d.h. in die gleiche Richtung wie die individuellen Anschlüsse 22.3. While in the case of the multi-phase inductance module illustrated in FIGS. 1 to 5, each conductor 3 has two individual terminals 22 formed by the terminal sections 15 in the multiphase inductance module shown in FIGS. 8 and 9, the conductors 3.3 are in each case in contact with one of their two ends with a common connection 23. This comprises a connection ring 24 arranged around the axis 7.3 and a connection lug 25 arranged thereon. The connection ring 24 is arranged approximately at the height of the upper core disk 5.3. The associated with him ends 26 of the conductors 3.3 are accordingly, deviating from the embodiment of FIGS. 1 to 5, bent upwards, ie in the direction opposite to the individual terminals 22.3 direction. The terminal lug 25 is directed parallel to the axis 7.3 downwards, ie in the same direction as the individual ports 22.3.
