Arrière-plan technologiqueTechnology background

L’article « Single-Stage Isolated Electrolytic Capacitor-Less EV Onboard Charger With Power Decoupling » de Ali Tausif, Hoyoung Jung et Sewan Choi, publié dans « CPSS transactions on power electronics and applications » en mars 2019, décrit une alimentation électrique comportant :

  • deux bornes d’entrée, une borne de masse, une borne intermédiaire, et deux bornes de sortie ;
  • pour chaque borne d’entrée :
    • un convertisseur de tension continu/continu connecté, en entrée, entre la borne d’entrée considérée et la borne de masse et, en sortie, entre la borne intermédiaire et la borne de masse, le convertisseur de tension continu/continu comportant un pont complet amont d’interrupteurs commandables, connecté entre la borne intermédiaire et la borne de masse,
    • un transformateur d’isolation galvanique comportant un primaire connecté au pont complet amont, et un secondaire, et
    • un redresseur aval connecté, en entrée, au secondaire du transformateur et, en sortie, aux bornes de sortie ; et
  • un dispositif de commande des ponts complets amont, dans un mode direct de transfert d’énergie électrique des bornes d’entrée jusqu’aux bornes de sortie.
The article "Single-Stage Isolated Electrolytic Capacitor-Less EV Onboard Charger With Power Decoupling" by Ali Tausif, Hoyoung Jung and Sewan Choi, published in "CPSS transactions on power electronics and applications" in March 2019, describes a power supply comprising:
  • two input terminals, a ground terminal, an intermediate terminal, and two output terminals;
  • for each input terminal:
    • a DC/DC voltage converter connected, at input, between the relevant input terminal and the ground terminal and, at output, between the intermediate terminal and the ground terminal, the DC/DC voltage converter comprising a full bridge upstream of controllable switches, connected between the intermediate terminal and the ground terminal,
    • a galvanic isolation transformer comprising a primary connected to the upstream full bridge, and a secondary, and
    • a downstream rectifier connected, at the input, to the secondary of the transformer and, at the output, to the output terminals; And
  • a control device for the upstream full bridges, in a direct mode of electrical energy transfer from the input terminals to the output terminals.

Plus précisément, les convertisseurs de tension continu/continu sont des convertisseurs élévateurs entrelacés et les redresseurs aval sont des ponts complets de diodes.More specifically, the DC/DC voltage converters are interleaved boost converters and the downstream rectifiers are full diode bridges.

Cette alimentation électrique connue présente plusieurs avantages, mais ne permet pas en revanche de transférer de la puissance électrique dans le sens inverse, depuis les bornes de sortie vers les bornes d’entrée.This known power supply has several advantages, but on the other hand does not make it possible to transfer electrical power in the opposite direction, from the output terminals to the input terminals.

Il peut ainsi être souhaité de garder les avantages de l’alimentation électrique connue, mais en la rendant réversible.It may thus be desired to keep the advantages of the known power supply, but by making it reversible.

Il est donc proposé une alimentation électrique comportant :

  • plusieurs bornes d’entrée, une borne de masse, une borne intermédiaire, et deux bornes de sortie ;
  • pour chaque borne d’entrée :
    • un convertisseur de tension continu/continu connecté, en entrée, entre la borne d’entrée considérée et la borne de masse et, en sortie, entre la borne intermédiaire et la borne de masse, le convertisseur de tension continu/continu comportant un pont complet amont d’interrupteurs commandables, connecté entre la borne intermédiaire et la borne de masse,
    • un transformateur d’isolation galvanique comportant un primaire connecté au pont complet amont, et un secondaire, et
    • un redresseur aval connecté, en entrée, au secondaire du transformateur et, en sortie, aux bornes de sortie ; et
  • un dispositif de commande des ponts complets amont, dans un mode direct de transfert d’énergie électrique des bornes d’entrée jusqu’aux bornes de sortie ;
caractérisée en ce que :
  • le redresseur aval comporte un pont complet aval d’interrupteurs commandables, connecté, en entrée, au secondaire du transformateur et, en sortie, aux bornes de sortie ; et
  • le dispositif de commande est conçu, dans un mode inverse de transfert d’énergie électrique des bornes de sortie jusqu’aux bornes d’entrée, pour :
    • commander chaque pont complet amont selon une commande amont conduisant, à certains moments, à une mise en court-circuit du primaire du transformateur, et
    • pour commander chaque pont complet aval pour déconnecter chaque secondaire des bornes de sortie lorsque le primaire associé est en court-circuit.
A power supply is therefore proposed comprising:
  • several input terminals, a ground terminal, an intermediate terminal, and two output terminals;
  • for each input terminal:
    • a DC/DC voltage converter connected, at input, between the relevant input terminal and the ground terminal and, at output, between the intermediate terminal and the ground terminal, the DC/DC voltage converter comprising a full bridge upstream of controllable switches, connected between the intermediate terminal and the ground terminal,
    • a galvanic isolation transformer comprising a primary connected to the upstream full bridge, and a secondary, and
    • a downstream rectifier connected, at the input, to the secondary of the transformer and, at the output, to the output terminals; And
  • a control device for the upstream full bridges, in a direct mode of electrical energy transfer from the input terminals to the output terminals;
characterized in that:
  • the downstream rectifier comprises a downstream full bridge of controllable switches, connected, at the input, to the secondary of the transformer and, at the output, to the output terminals; And
  • the control device is designed, in an inverse mode of transfer of electrical energy from the output terminals to the input terminals, for:
    • controlling each upstream full bridge according to an upstream command leading, at certain times, to a short-circuiting of the primary of the transformer, and
    • to control each downstream full bridge to disconnect each secondary from the output terminals when the associated primary is shorted.

Grâce à l’invention, l’alimentation électrique est réversible, avec peu de modifications par rapport à l’alimentation électrique connue : remplacement des ponts complets de diodes par des ponts complets d’interrupteurs et ajout d’une commande des interrupteurs des ponts complets amont et aval dans le mode inverse.Thanks to the invention, the power supply is reversible, with few modifications compared to the known power supply: replacement of the complete bridges of diodes by complete bridges of switches and addition of a control of the switches of the complete bridges upstream and downstream in the reverse mode.

En particulier, l’alimentation électrique est une alimentation électrique isolée.In particular, the power supply is an isolated power supply.

De façon optionnelle, le dispositif de commande est conçu, dans le mode inverse, pour commander chaque pont complet amont à une fréquence de découpage et selon un rapport cyclique variant à une basse fréquence, c’est-à-dire au moins cent fois inférieure à la fréquence de découpage.Optionally, the control device is designed, in the inverse mode, to control each upstream full bridge at a chopping frequency and according to a duty cycle varying at a low frequency, that is to say at least a hundred times lower at the switching frequency.

De façon optionnelle également, chaque convertisseur de tension continu/continu présente un gain dépendant du rapport cyclique selon lequel le pont complet amont du convertisseur de tension continu/continu considéré est commandé, et dans laquelle le dispositif de commande est conçu, dans le mode inverse, pour faire varier le rapport cyclique sinusoïdalement à la basse fréquence pour générer, entre la borne d’entrée du convertisseur de tension continu/continu considéré et la borne de masse, une tension sinusoïdale à la basse fréquence avec composante continue, pour être de signe constant.Also optionally, each DC/DC voltage converter has a gain depending on the duty cycle according to which the upstream full bridge of the DC/DC voltage converter considered is controlled, and in which the control device is designed, in the inverse mode , to vary the duty cycle sinusoidally at the low frequency to generate, between the input terminal of the DC/DC voltage converter considered and the ground terminal, a sinusoidal voltage at the low frequency with DC component, to be of sign constant.

De façon optionnelle également, chaque pont complet amont comporte deux bras de commutation connectés entre la borne intermédiaire et la borne de masse et présentant des points milieu respectifs entre lesquels le primaire du transformateur associé est connecté.Also optionally, each upstream full bridge comprises two switching arms connected between the intermediate terminal and the ground terminal and having respective midpoints between which the primary of the associated transformer is connected.

De façon optionnelle également, le dispositif de commande est conçu, dans le mode direct et/ou le mode inverse, pour commuter les deux bras de commutation de chaque pont complet amont selon le rapport cyclique associé, mais avec un déphasage entre les deux bras de commutation.Also optionally, the control device is designed, in the direct mode and/or the inverse mode, to switch the two switching arms of each upstream full bridge according to the associated duty cycle, but with a phase difference between the two switching arms. switching.

De façon optionnelle également, le déphasage est de 180°.Also optionally, the phase shift is 180°.

De façon optionnelle également, le convertisseur continu/continu est un convertisseur élévateur entrelacé comportant deux inductances connectées entre la borne d’entrée et respectivement les deux points milieu des deux bras de commutation.Also optionally, the DC/DC converter is an interlaced boost converter comprising two inductances connected between the input terminal and respectively the two midpoints of the two switching arms.

De façon optionnelle également, chaque convertisseur continu/continu comporte au moins une capacité de stockage pilotable d’énergie électrique.Also optionally, each DC/DC converter comprises at least one controllable electrical energy storage capacity.

De façon optionnelle également, le dispositif de commande est conçu pour piloter le stockage d’énergie de la ou des capacités de stockage en modifiant, pour chaque paire d’entrée consécutives, la somme des rapports cycliques ou bien la somme des carrés des rapports cycliques des deux ponts complets amont associés.Also optionally, the control device is designed to control the energy storage of the storage capacitor(s) by modifying, for each pair of consecutive inputs, the sum of the duty cycles or else the sum of the squares of the duty cycles of the two associated upstream complete bridges.

De façon optionnelle également, les bornes d’entrée sont au nombre d’au moins trois et le dispositif de commande est conçu pour commander les ponts complets amont suivant des rapports cycliques respectifs et pour réguler une tension de sortie entre les bornes de sortie en modifiant, pour chaque paire de bornes d’entrée consécutives en considérant les bornes d’entrée ordonnées de manière cyclique, la différence des rapports cycliques des deux ponts complets amont associés. Ainsi, l’alimentation électrique est adaptée à un réseau polyphasé tout en nécessitant moins de composants que la solution consistant à dupliquer l’alimentation électrique connue pour chaque tension différentielle du réseau électrique.Also optionally, the input terminals are at least three in number and the control device is designed to control the upstream full bridges according to respective duty cycles and to regulate an output voltage between the output terminals by modifying , for each pair of consecutive input terminals considering the input terminals ordered in a cyclic manner, the difference in the duty ratios of the two associated upstream full bridges. Thus, the power supply is suitable for a polyphase network while requiring fewer components than the solution of duplicating the known power supply for each differential voltage of the power network.

De façon optionnelle également, la borne de masse comporte un premier conducteur en boucle et la borne intermédiaire comporte un deuxième conducteur en boucle, l’un des premier et deuxième conducteurs s’étendant à l’intérieur de l’autre.Also optionally, the ground terminal comprises a first loop conductor and the intermediate terminal comprises a second loop conductor, one of the first and second conductors extending inside the other.

De façon optionnelle, la borne de masse est différente d’un neutre du réseau électrique, c’est-à-dire non mise au même potentiel.Optionally, the ground terminal is different from a neutral of the electrical network, i.e. not placed at the same potential.
