Abstract

La présente invention concerne un circuit convertisseur (50) pour le transfert d'énergie électrique, en particulier destiné à une utilisation dans le réseau d'alimentation de bord (38, 42) d'un véhicule automobile, doté d'une unité de transfert électromagnétique (60), qui présente trois organes de transfert électromagnétiques (62, 64, 66) qui peuvent être couplés électromagnétiquement les uns aux autres pour le transfert d'énergie électromagnétique. Le premier organe de transfert électromagnétique (62) est raccordé à un premier circuit convertisseur bidirectionnel, qui présente une première paire (80) de bornes de tension pour y raccorder une source de tension alternative (54). Le deuxième organe de transfert électromagnétique (64) est relié à un circuit convertisseur redresseur dont la sortie est raccordée à un accumulateur d'énergie électrique (88). Le troisième organe de transfert électromagnétique (66) est raccordé à un deuxième circuit convertisseur bidirectionnel, qui présente une deuxième paire (96) de bornes de tension pour le raccordement d'une source de tension continue (98). Le circuit est également doté d'une unité de commande (100), qui est raccordée au premier circuit convertisseur bidirectionnel, au deuxième circuit convertisseur bidirectionnel et au circuit convertisseur redresseur pour régler l'échange d'énergie électrique entre la source de tension alternative (54), la source de tension continue (98) et/ou l'accumulateur électrique (88).
