Abstract
Die Erfindung betrifft eine Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten, bei der die Funktionseinheiten aus einer hochfrequenten Wechselspannung gespeist werden, die für jede der Funktionseinheiten individuell über eine Drossel ausgekoppelt wird. Um mit geringem Aufwand eine Vielzahl von Funktionseinheiten zu speisen, wird vorgeschlagen, die Mehrebenenleiterplatte (3) jeder Drossel (1) parallel zur Ebene ihrer Leiterbahnen (2) zumindest teilweise mit einer flachen Platte (5) eines magnetischen Materials zu bedecken. The invention relates to a power supply device for explosion-proof electronic functional units, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle. In order to feed a large number of functional units with little effort, it is proposed to cover the multi-level printed circuit board (3) of each choke (1) parallel to the plane of its printed conductors (2) at least partially with a flat plate (5) of a magnetic material.
Description
Die Erfindung betrifft eine Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten.The invention relates to a power supply device for explosion-proof electronic functional units.
Derartige Energieversorgungseinrichtung werden in automatisierungstechnischen Anlagen zur Speisung von prozessnahen Komponenten und diesen zugeordneten Kommunikationseinrichtungen eingesetzt.Such energy supply device are used in automation systems for supplying process-related components and associated communication devices.
Aus der
Dieser Anordnung ist mit mehreren Nachteilen behaftet. Durch die Vielzahl der Ausnehmungen und ihre Bestückung mit jeweils zwei Ferritkernhälften ist der Hestellungsaufwand für die Mehrebenenleiterplatte sehr hoch. Weiterhin ist zum Erreichen der erforderlichen Induktivität der Drosseln eine Mehrebenenleiterplatte mit mindestens sechs Metallisierungsebenen erforderlich, während für die restliche Verdrahtung vier Metallisierungsebenen genügen. Schließlich begrenzt die Fläche der Drosseln innerhalb der Mehrebenenleiterplatte die Anzahl der anschaltbaren Funktionseinheiten.This arrangement has several disadvantages. Due to the large number of recesses and their placement with two ferrite core halves of the Hestellungsaufwand for the multi-level PCB is very high. Furthermore, to achieve the required inductance of the chokes, a multilevel printed circuit board having at least six levels of metallization is required, while four levels of metallization are sufficient for the remainder of the wiring. Finally, the area of the limited Restrict the number of connectable functional units within the multilevel PCB.
Aus dem deutschen Gebrauchsmuster
Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile des Standes der Technik zu überwinden und eine wechselspannungsspeisende Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten anzugeben, die mit geringem Aufwand eine Vielzahl von Funktionseinheiten speisen kann.The invention is therefore based on the object to overcome the disadvantages of the prior art and to provide an AC voltage supplying power supply device for explosion-proof electronic functional units that can feed a variety of functional units with little effort.
Erfindungsgemäß wird diese Aufgabe mit den Mitteln des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den rückbezogenen Ansprüchen angegeben.According to the invention this object is achieved by the means of
Die Erfindung geht aus von einer Energieversorgungseinrichtung für explosionsgeschützte elektronische Funktionseinheiten, bei der die Funktionseinheiten aus einer hochfrequenten Wechselspannung gespeist werden, die für jede der Funktionseinheiten individuell über eine Drossel ausgekoppelt wird, welche als Mehrebenenleiterplatte ausgebildet und stehend auf einer Verteilungsleiterplatte angeordnet ist.The invention relates to a power supply device for explosion-proof electronic functional units, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle, which is formed as a multi-level printed circuit board and standing on a distribution board.
Erfindungsgemäß ist die Mehrebenenleiterplatte jeder Drossel parallel zur Ebene ihrer Leiterbahnen zumindest teilweise mit einer flachen Platte eines magnetischen Materials bedeckt.According to the invention, the multi-level printed circuit board of each choke is at least partially covered with a flat plate of a magnetic material parallel to the plane of its interconnects.
Dadurch wird das von jeder Drossel ausgehende magnetische Feld in unmittelbarer Nähe der Drossel derart geformt, dass eine Beeinflussung benachbarter Drosseln weitgehend vermieden wird.As a result, the magnetic field emanating from each throttle is formed in the immediate vicinity of the throttle in such a way that influencing adjacent throttles is largely avoided.
Darüber hinaus bewirkt die Platte magnetischen Materials eine Erhöhung der Induktivität der Drossel bei gleichen mechanischen Parametern.In addition, the plate of magnetic material causes an increase in the inductance of the throttle with the same mechanical parameters.
Vorteilhafterweise kommt die Formung des magnetischen Feldes der Drossel ohne mechanisch aufwändige Ausnehmungen in der Mehrebenenleiterplatte aus.Advantageously, the shaping of the magnetic field of the throttle without mechanically elaborate recesses in the multi-level printed circuit board.
In einer vorteilhaften Weiterbildung der Erfindung besteht jede Drossel aus zwei Wicklungen mit entgegengesetztem Wicklungssinn. Dadurch wird die Formung des magnetischen Feldes der Drossel verstärkt.In an advantageous development of the invention, each throttle consists of two windings with opposite winding sense. This enhances the formation of the magnetic field of the reactor.
Unmittelbar benachbarte Drosseln weisen beidseitig feldformende Platten aus magnetischem Material auf. Dadurch wird die räumliche Ausdehnung des magnetischen Feldes auf den Nahbereich um die jeweilige Drossel begrenzt.Immediately adjacent chokes have on both sides field-forming plates of magnetic material. As a result, the spatial extent of the magnetic field is limited to the near range around the respective throttle.
Vorteilhafterweise können die Drosseln in hoher Packungsdichte auf der Verteilungsleiterplatte bei vernachlässigbarer gegenseitiger Beeinflussung angeordnet werden, so dass eine größere Anzahl Drosseln auf derselben Fläche der Verteilungsleiterplatte untergebracht werden. Dementsprechend mehr Funktionseinheiten sind bei gleichen Dimensionen an die Verteilungsleiterplatte anschaltbar.Advantageously, the chokes can be arranged in high packing density on the distribution board with negligible interference, so that a larger number of chokes are accommodated on the same area of the distribution board. Accordingly, more functional units can be connected to the distribution board with the same dimensions.
Ein weiterer Vorteil dieser Anordung ist die Unempfindlichkeit des Induktivitätswertes gegenüber Bruch oder Teilverlust der Platte. Somit ist mit einfachen Mitteln die für den Explosionschutz erfoderlicher Mindesinduktivität der Drossel gewährleistet.Another advantage of this arrangement is the insensitivity of the inductance value to breakage or partial loss of the plate. Thus, with simple means erfulflicher for explosion protection Mindesinduktivität the throttle is guaranteed.
