Abstract

L'invention concerne un dispositif (100) servant à charger un accumulateur d'énergie électrique (B) à partir d'une source de tension alternative triphasée (W1, W2, W3) dont chaque phase contient : - un circuit abaisseur de tension (TS1...TS3) comprenant un commutateur (STS1...STS3) ; - une diode (FLD) connectée en parallèle sur le circuit abaisseur de tension (TS1...TS3) ; - un circuit mutateur (U), connecté au circuit abaisseur de tension (TS1...TS3), comprenant au moins un premier demi-pont (H1) avec deux commutateurs (S1, S2) connectés en série, une inductance (L4) étant connectée entre un point de liaison des deux commutateurs (S1, S2) du premier demi-pont (H1) et le circuit abaisseur de tension (TS1...TS3). Un circuit redresseur (D11...D33) du circuit abaisseur de tension (TS1...TS3) définit un sens du courant dans l'inductance (L4). En fonction des tensions de la source de tension alternative (W1, W2, W3) et d'un courant circulant dans l'inductance (L4), un circuit de commande (10) active les commutateurs (STS1...STS3) du circuit abaisseur de tension (TS1...TS3) et au moins un deuxième commutateur (S2) du premier demi-pont (H1) du circuit mutateur (U) afin de générer un courant prélevé de la source de tension alternative (W1, W2, W3) pour charger l'accumulateur d'énergie électrique (B) de telle façon que chaque phase de la source de tension alternative (W1, W2, W3) délivre un courant pratiquement sinusoïdal, le courant et la tension correspondante de la source de tension alternative (W1, W2, W3) étant pratiquement en phase dans chacune des phases.
