Abstract

L'invention concerne une topologie d'onduleur bidirectionnel située entre un réseau électrique à courant alternatif et une batterie rechargeable à courant continu qui met en œuvre la charge et la décharge entre la batterie rechargeable à courant continu et le réseau électrique à courant alternatif. La topologie comprend un circuit de convertisseur continu-continu bidirectionnel, un circuit d'onduleur bidirectionnel, un circuit de filtrage et de protection de courant continu du côté haute tension, un condensateur de filtrage de courant continu du côté haute tension, un circuit de détection et un circuit d'attaque et de commande. Le circuit de convertisseur continu-continu bidirectionnel fonctionne comme suit : lorsque la batterie rechargeable à courant continu est en décharge, l'onde de tension du côté haute tension est une demi-onde positive variant de manière sinusoïdale, ce qui permet à la partie d'onduleur de ne devoir fonctionner que dans un état de fréquence de puissance qui n'est pas dans un état de modulation d'impulsions haute fréquence, et ce qui réduit considérablement la consommation de commutation du circuit en pont CC/CA. Pendant ce temps, un transformateur de puissance haute fréquence doté d'une efficacité élevée est adopté pour mettre en œuvre la conversion de la partie CC/CC, ce qui développe la fonction de survoltage, de fonçage et d'isolation électrique et ce qui augmente considérablement le rendement de conversion dans son ensemble.
