DOMAINE DE L'INVENTION FIELD OF THE INVENTION
La présente invention concerne un dispositif de charge comprenant un convertisseur AC-DC permettant d'alimenter deux sorties à des tensions différentes, de type réversible. Ce dispositif de charge est particulièrement approprié pour une utilisation en tant que dispositif embarqué dans un véhicule automobile électrique.  The present invention relates to a charging device comprising an AC-DC converter for supplying two outputs at different voltages, reversible type. This charging device is particularly suitable for use as a device embedded in an electric motor vehicle.
ARRIERE-PLAN TECHNIQUE TECHNICAL BACKGROUND
De nombreux engins mobiles utilisent l'énergie électrique et sont équipés de batteries, par exemple des véhicules électriques, des nacelles, des transpalettes... Ces engins comprennent généralement des chargeurs embarqués, c'est-à-dire des chargeurs de batteries électriques qui sont montés directement sur les engins mobiles. Ils peuvent également être utilisés avec un dispositif chargeur de batterie externe.  Many mobile machines use electrical energy and are equipped with batteries, for example electric vehicles, nacelles, pallet trucks ... These machines generally include on-board chargers, that is to say electric battery chargers that are mounted directly on mobile gear. They can also be used with an external battery charger device.
La fonction principale de ces chargeurs est la recharge des batteries à partir de l'électricité disponible sur le réseau de distribution électrique. Ils assurent donc une conversion d'un courant alternatif en courant continu.  The main function of these chargers is the recharging of the batteries from the electricity available on the electrical distribution network. They therefore provide a conversion of an alternating current into direct current.
Pour des raisons d'autonomie et de rendement, la ou les batteries de traction (qui sont utilisées pour alimenter le système de traction, c'est-à-dire la motorisation, des engins ci-dessus) ont des tensions élevées (par exemple 48 V, 60 V, voire 400 V et plus), alors que l'électronique embarquée demande une tension plus faible. La tension nominale la plus répandue est de 12 V : elle correspond aux équipements traditionnellement utilisés dans l'environnement automobile.  For reasons of autonomy and efficiency, the traction battery or batteries (which are used to power the traction system, that is to say the engine, of the above-mentioned machines) have high voltages (for example 48 V, 60 V or 400 V and above), while the onboard electronics require a lower voltage. The most common rated voltage is 12 V, which corresponds to equipment traditionally used in the automotive environment.
Il est donc nécessaire d'ajouter un convertisseur de tension continu- continu (DC-DC), qui abaisse la tension de la batterie de traction à la valeur demandée par les équipements de bord.  It is therefore necessary to add a DC-DC voltage converter, which lowers the voltage of the traction battery to the value demanded by the on-board equipment.
Il est avantageux d'intégrer à la fois ce convertisseur DC-DC et les moyens de charge de la batterie de traction dans un même dispositif de charge, pour effectuer des gains de volume, de poids, de connectique, de fiabilité, et pour faciliter l'intégration de ces équipements dans le véhicule ou autre engin motorisé. It is advantageous to integrate both this DC-DC converter and the charging means of the traction battery in the same charging device, to make gains in volume, weight, connectivity, reliability, and to facilitate the integration of such equipment in the vehicle or other motorized vehicle.
Toutefois, il reste encore souhaitable de réduire l'encombrement et le poids des dispositifs de charge de ce type.  However, it is still desirable to reduce the size and weight of charging devices of this type.

La présente invention permet de surmonter les inconvénients de l'état de la technique. Elle fournit plus particulièrement un dispositif de charge permettant d'alimenter à la fois une batterie de traction à une tension relativement élevée et des équipements du réseau dit « très basse tension », ce dispositif de charge présentant un encombrement et un poids plus réduits que dans l'état de la technique.  The present invention overcomes the disadvantages of the state of the art. It provides more particularly a charging device for supplying both a traction battery at a relatively high voltage and equipment of the so-called "very low voltage" network, this charging device having a smaller footprint and weight than in the state of the art.
L'invention permet également de simplifier la connectique, de disposer d'un système plus fiable, et de faciliter l'intégration du dispositif de charge dans l'appareil motorisé.  The invention also simplifies the connection, to have a more reliable system, and facilitate the integration of the charging device in the motorized device.
Ceci est accompli grâce à la mise au point d'un convertisseur DC-DC (appelé deuxième module de conversion dans le cadre de la demande) permettant d'alimenter à la fois la batterie de traction et les équipements de très basse tension, ledit convertisseur DC-DC étant réversible, c'est-à-dire pouvant être alimenté aussi bien par une source externe que par la batterie de traction, et reposant sur un transformateur unique. This is accomplished through the development of a DC-DC converter (called the second conversion module as part of the application) for supplying both the traction battery and the very low voltage equipment, said DC-DC converter being reversible, that is to say able to be powered both by an external source and by the traction battery, and based on a single transformer.
Ainsi, on évite d'utiliser au moins deux transformateurs, à savoir un pour l'alimentation de la batterie de traction, et un pour l'alimentation des équipements à très basse tension, comme c'est le cas selon l'état de la technique.  Thus, it is avoided to use at least two transformers, namely one for the supply of the traction battery, and one for the supply of the equipment with very low voltage, as it is the case according to the state of the technical.
Le transformateur unique offre une isolation galvanique entre les trois types de courants continus circulant dans le système, ce qui permet de répondre aux exigences normatives en matière de sécurité, en particulier lorsque la tension de la batterie est élevée et doit donc être isolée des équipements de bord.  The single transformer provides galvanic isolation between the three types of DC currents flowing in the system, which meets the safety requirements, especially when the battery voltage is high and must be isolated from the equipment. edge.
Du fait de l'utilisation d'un transformateur unique, celui-ci peut transférer la même puissance électrique vers la batterie principale et à partir de celle-ci. Ainsi, sans augmenter le poids et le volume du dispositif de charge, on dispose d'une puissance importante en mode de roulage pour les équipements de bord. Cela est d'autant plus avantageux que les équipements de bord ont tendance de nos jours à être de plus en plus consommateurs de puissance électrique en mode de roulage, avec par exemple des pointes de consommation à 2 kW pour des équipements de voiture électrique.  Due to the use of a single transformer, it can transfer the same electrical power to and from the main battery. Thus, without increasing the weight and the volume of the load device, there is a significant power in rolling mode for on-board equipment. This is all the more advantageous as on-board equipment tends today to be more and more consumers of electric power in running mode, for example with peak consumption of 2 kW for electric car equipment.

Dans ce mode de fonctionnement, la batterie 5 alimente en courant continu de tension V2 le deuxième module de conversion 4, qui convertit ce courant en courant continu de tension V3 alimentant les équipements 7a, 7b, 7c.  In a second mode of operation, called a driving mode and shown in FIG. 2, the charging device is disconnected from any external power source. In this mode of operation, the battery 5 supplies DC voltage V2 to the second conversion module 4, which converts this current into a DC voltage V3 supplying the equipment 7a, 7b, 7c.
Deux modes de redistribution sont également possibles : le troisième mode de fonctionnement, représenté à la figure 5, et le quatrième mode de fonctionnement (facultatif), représenté à la figure 3.  Two modes of redistribution are also possible: the third mode of operation, represented in FIG. 5, and the fourth mode of operation (optional), represented in FIG.
Dans le quatrième mode de fonctionnement, la batterie 5 alimente en courant continu de tension V2 le deuxième module de conversion 4, qui convertit ce courant en courant continu de tension V1 alimentant le premier module de conversion 3, et le premier module de conversion 3 convertit ce courant continu de tension V1 en courant alternatif de sortie, qui est fourni vers l'extérieur de l'appareil motorisé 6, c'est-à-dire par exemple qui est redistribué vers le réseau électrique, dans le cadre d'une gestion dite « intelligente » de l'énergie électrique, permettant notamment de répondre à des pics de consommation sur le réseau électrique en faisant appel aux batteries des appareils motorisés reliés au dit réseau.  In the fourth mode of operation, the battery 5 supplies DC voltage V2 to the second conversion module 4, which converts this current into a DC voltage V1 supplying the first conversion module 3, and the first conversion module 3 converts this direct current of voltage V1 AC output, which is supplied to the outside of the motorized device 6, that is to say, for example, which is redistributed to the electrical network, as part of a management said "smart" of electrical energy, including responding to peak consumption on the power network by using the batteries of motorized devices connected to said network.
Il faut souligner en outre que, dans le cadre de ce mode de redistribution, il peut également y avoir une alimentation des équipements 7a, 7b, 7c en courant continu de tension V3 par le deuxième module de conversion 4, tout comme dans le mode de roulage.  It should also be emphasized that, in the context of this mode of redistribution, there can also be a supply of the equipment 7a, 7b, 7c in direct current of voltage V3 by the second conversion module 4, just as in the mode of rolling.
En faisant référence à la figure 5, dans le troisième mode de fonctionnement, qui suppose que les équipements 7a, 7b, 7c comprennent une batterie secondaire 7a, celle-ci alimente le deuxième module de conversion 4 en courant continu de tension V3, par exemple pour conversion en courant continu de tension V1 et alimentation du premier module de conversion 3.  Referring to FIG. 5, in the third mode of operation, which assumes that the devices 7a, 7b, 7c comprise a secondary battery 7a, this latter supplies the second conversion module 4 with a DC voltage V3, for example for converting to DC voltage V1 and supplying the first conversion module 3.
Le courant alternatif ainsi produit en sortie du premier module de conversion 3 peut être redistribué vers le réseau électrique, tout comme dans le quatrième mode de fonctionnement. Alternativement, et comme illustré sur la figure, il peut servir à alimenter des équipements supplémentaires 12 branchés sur l'appareil motorisé, de préférence de puissance relativement peu élevée, par exemple des équipements électroniques amovibles, comme un ordinateur portable, un téléphone portable, une tablette numérique ou autre. Avantageusement ces équipements supplémentaires peuvent être connectés par l'intermédiaire de prises conventionnelles, qui sont également adaptées à relier ces équipements supplémentaires au secteur. The alternating current thus produced at the output of the first conversion module 3 can be redistributed towards the electrical network, just as in the fourth mode of operation. Alternatively, and as illustrated in the figure, it can be used to power additional equipment 12 connected to the motorized device, preferably relatively low power, for example removable electronic equipment, such as a laptop, a mobile phone, digital tablet or other. Advantageously these additional equipment can be connected via conventional sockets, which are also adapted to connect these additional equipment to the sector.
Le courant alternatif d'entrée peut être soit monophasé, par exemple avec une tension de 85 à 265 V, soit biphasé, par exemple avec une tension de 200 à 250 V, soit multiphasé et notamment triphasé, par exemple avec une tension de 380 à 420 V.  The AC input current can be either single-phase, for example with a voltage of 85 to 265 V, or two-phase, for example with a voltage of 200 to 250 V, or multiphase and in particular three-phase, for example with a voltage of 380 to 420 V.
Le premier module de conversion 3 comporte en général un circuit correcteur de puissance (PFC), afin de limiter les harmoniques de courant d'entrée. Un tel circuit présente également l'avantage de fonctionner sur une large plage de tensions d'entrée.  The first conversion module 3 generally comprises a power correction circuit (PFC), in order to limit the input current harmonics. Such a circuit also has the advantage of operating over a wide range of input voltages.
La tension V1 du courant continu issu du premier module de conversion 3 et alimentant le deuxième module de conversion 4 (ou éventuellement inversement) vaut en général de 270 à 440 V, de préférence de 290 à 430 V. A titre d'exemple, ce courant peut avoir une tension d'environ 400 V.  The voltage V1 of the direct current coming from the first conversion module 3 and supplying the second conversion module 4 (or possibly vice versa) is generally from 270 to 440 V, preferably from 290 to 430 V. For example, this current can have a voltage of about 400 V.
La tension V2 du courant continu issu du deuxième module de conversion 4 et alimentant la batterie 5 (ou inversement) vaut en général de 20 à 550 V, de préférence de 24 à 500 V. Selon un mode de réalisation, la tension V2 est égale ou pratiquement égale à la tension V1 . Elle peut ainsi être de 400 V environ. Selon un autre mode de réalisation, la tension V2 est inférieure à la tension V1 . Par exemple, la tension V2 peut être de 60 V environ.  The voltage V2 of the direct current coming from the second conversion module 4 and supplying the battery 5 (or vice versa) is generally from 20 to 550 V, preferably from 24 to 500 V. According to one embodiment, the voltage V2 is equal to or substantially equal to the voltage V1. It can thus be about 400 V. According to another embodiment, the voltage V2 is lower than the voltage V1. For example, the voltage V2 may be about 60 V.
Il faut noter que la valeur de la tension V2 peut varier au cours du temps : c'est en principe la batterie 5 (et son niveau de charge) qui impose la valeur de la tension V2.  It should be noted that the value of the voltage V2 can vary over time: it is in principle the battery 5 (and its charge level) that imposes the value of the voltage V2.
La tension V1 peut également varier en fonction de la tension V2, par exemple grâce à une adaptation des conditions de fonctionnement du premier module de conversion 3 à la tension V2 délivrée, selon le niveau de charge de la batterie.  The voltage V1 may also vary depending on the voltage V2, for example by adapting the operating conditions of the first conversion module 3 to the voltage V2 delivered, depending on the charge level of the battery.
La tension V3 du courant continu issu du deuxième module de conversion 4 et alimentant les équipements 7a, 7b, 7c (éventuellement ou inversement) est généralement inférieure à la tension V1 et inférieure à la tension V2. The voltage V3 of the direct current coming from the second conversion module 4 and supplying the equipment 7a, 7b, 7c (possibly or conversely) is generally lower than the voltage V1 and lower than the voltage V2.
Elle vaut typiquement de 5 à 20 V, de préférence de 10 à 15 V, par exemple environ 12 V.  It is typically 5 to 20 V, preferably 10 to 15 V, for example about 12 V.
En faisant référence à la figure 4, on décrit un exemple de deuxième module de conversion 4 réversible selon l'invention.  With reference to FIG. 4, an example of a second reversible conversion module 4 according to the invention is described.
Ainsi, le deuxième module de conversion 4 comprend un premier circuit de de conversion 8, un deuxième circuit de conversion 9 et un troisième circuit de conversion 10.  Thus, the second conversion module 4 comprises a first conversion circuit 8, a second conversion circuit 9 and a third conversion circuit 10.
Ces trois circuits de conversion 8, 9, 10 sont connectés à un transformateur unique 1 1 , c'est-à-dire un transformateur comportant un unique élément magnétique et au moins trois enroulements reliés à chacun des trois circuits de conversion 8, 9, 10.  These three conversion circuits 8, 9, 10 are connected to a single transformer 1 1, that is to say a transformer comprising a single magnetic element and at least three windings connected to each of the three conversion circuits 8, 9, 10.
Le premier circuit de conversion 8 est connecté au premier module de conversion 3 par une de ses extrémités opposée à celle en liaison avec le transformateur 1 1 . Ainsi, ce premier circuit de conversion 8 permet de convertir un courant continu de tension V1 en entrée en un courant alternatif intermédiaire alimentant le transformateur 1 1 , ou éventuellement inversement.  The first conversion circuit 8 is connected to the first conversion module 3 at one of its ends opposite to that in connection with the transformer 1 1. Thus, this first conversion circuit 8 makes it possible to convert a direct voltage current V1 into an intermediate alternating current supplying the transformer 11, or possibly vice versa.
Le deuxième circuit de conversion 9 est connecté à la batterie 5 par une de ses extrémités opposée à celle en liaison avec le transformateur 1 1 . Ainsi, ce deuxième circuit de conversion 9 permet de convertir un courant alternatif intermédiaire issu du transformateur 1 1 en courant continu de tension V2 en sortie alimentant la batterie 5 (en mode de charge), ou inversement (en mode de roulage ou de redistribution).  The second conversion circuit 9 is connected to the battery 5 at one of its ends opposite to that in connection with the transformer 1 1. Thus, this second conversion circuit 9 makes it possible to convert an intermediate AC current from the transformer 1 1 into a direct current of voltage V2 at the output supplying the battery 5 (in charge mode), or vice versa (in rolling or redistribution mode). .
Le troisième circuit de conversion 10 est connecté aux équipements 7a, 7b, 7c par une de ses extrémités opposée à celle en liaison avec le transformateur 1 1 . Ainsi, ce troisième circuit de conversion 10 permet de convertir un courant alternatif intermédiaire issu du transformateur 1 1 en courant continu de tension V3 en sortie alimentant les équipements 7a, 7b, 7c (en mode de charge ou de roulage ou éventuellement de redistribution), ou éventuellement inversement (dans certains modes de réalisation du mode de redistribution).  The third conversion circuit 10 is connected to the equipment 7a, 7b, 7c by one of its ends opposite to that in connection with the transformer 1 1. Thus, this third conversion circuit 10 makes it possible to convert an intermediate AC current originating from the transformer 1 1 into direct current of voltage V3 at the output supplying the equipment 7a, 7b, 7c (in charge or rolling or possibly redistribution mode), or possibly conversely (in some embodiments of the redistribution mode).
Ainsi, de préférence, le premier circuit de conversion 8, le deuxième circuit de conversion 9 et le troisième circuit de conversion 10 sont réversibles ; c'est-à-dire qu'ils peuvent fonctionner en mode « normal » ou en mode « inverse », l'entrée du circuit en mode normal correspondant à la sortie du circuit en mode inverse, et la sortie du circuit en mode normal correspondant à l'entrée du circuit en mode inverse. Thus, preferably, the first conversion circuit 8, the second conversion circuit 9 and the third conversion circuit 10 are reversible; that is, they can operate in "normal" or "reverse" mode, the input of the circuit in normal mode corresponding to the output of the circuit in reverse mode, and the output of the circuit in normal mode corresponding to the input of the circuit in reverse mode.
Les courants alternatifs intermédiaires mentionnés ci-dessus sont des courants alternatifs ayant une fréquence de découpage qui est de préférence relativement élevée.  The intermediate AC currents mentioned above are AC currents having a switching frequency which is preferably relatively high.
Chaque circuit de conversion 8, 9, 10 comporte par exemple un ensemble d'éléments de commutation (notés Q1 , Q2, Q3, Q4 ; Q5, Q6, Q7, Q8 ; et Q9, Q10, Q1 1 , Q12 sur la figure 4). Ces éléments de commutation sont actionnés de manière synchrone soit pour découper un courant continu en courant alternatif, soit pour redresser un courant alternatif en courant continu, selon le sens d'utilisation des circuits.  Each conversion circuit 8, 9, 10 for example comprises a set of switching elements (denoted Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8 and Q9, Q10, Q1 1, Q12 in FIG. ). These switching elements are operated synchronously either to cut a DC current to AC, or to rectify a DC current, according to the direction of use of the circuits.
De préférence, un organe de commande centralisé pourvu d'un programmateur numérique commande les trois circuits de conversion 8, 9, 10, notamment via les éléments de commutation.  Preferably, a centralized control member provided with a digital programmer controls the three conversion circuits 8, 9, 10, in particular via the switching elements.
Cet organe de commande peut notamment comporter des moyens de régulation de la tension V3 indépendamment (de manière décorrélée) de la tension V2. Cela est particulièrement avantageux afin d'éviter que les variations de la tension V2 selon le niveau de charge de la batterie 5 aient une quelconque influence sur l'alimentation électrique du réseau à très basse tension.  This control member may in particular comprise means for regulating the voltage V3 independently (in a decorrelated manner) of the voltage V2. This is particularly advantageous in order to avoid that the variations of the voltage V 2 according to the charge level of the battery 5 have any influence on the power supply of the very low-voltage network.
Lorsque l'un des circuits de conversion n'est pas employé, par exemple le premier circuit de conversion 8 en mode de roulage, il peut être déconnecté par un élément de commutation (relais).  When one of the conversion circuits is not used, for example the first conversion circuit 8 in rolling mode, it can be disconnected by a switching element (relay).
Chaque circuit de conversion 8, 9, 10, et notamment le troisième circuit de conversion 10, peut comprendre des moyens de redressement synchrone, permettant d'augmenter le rendement en commandant activement de manière synchrone les diodes et les composés de type MOSFET.  Each conversion circuit 8, 9, 10, and in particular the third conversion circuit 10, may comprise synchronous rectification means, making it possible to increase the efficiency by actively synchronously controlling the diodes and the MOSFET-type compounds.
