Abstract

L'invention concerne un système (100), comprenant au moins un module accumulateur d'énergie électrique (30 ; 35) conçu de sorte qu'il puisse être chargé ou déchargé, le ou les modules accumulateurs d'énergie électrique (30 ; 35) étant connectables ou connectés à une charge (40), et un système convertisseur de puissance (50) étant connectable ou connecté à une source d'énergie (60) qui transmet une puissance en CA ayant une pluralité de phases. Le système convertisseur de puissance (50) est conçu pour charger à plusieurs reprises le module ou au moins un des modules accumulateurs d'énergie électrique (30 ; 35). Le ou les modules accumulateurs d'énergie électrique (30 ; 35) sont connectables ou connectés à la charge (40) de sorte que, lorsque le ou les modules accumulateurs d'énergie électrique (30 ; 35) sont déchargés, une impulsion électrique est créée pour être reçue par la charge (40) lorsque le ou les modules accumulateurs d'énergie électrique (30 ; 35) sont connectés à la charge (40). En chargeant et en déchargeant à plusieurs reprises le ou les modules accumulateurs d'énergie électrique (30 ; 35), une pluralité d'impulsions électriques successives sont créées pour être reçues par la charge (40) lorsque le ou les modules accumulateurs d'énergie électrique (30 ; 35) sont connectés à la charge (40). Le système convertisseur de puissance (50) comprend un redresseur d'entrée (70) servant à recevoir la puissance en CA transmise par la source d'énergie, le redresseur d'entrée (70) étant un redresseur multiphasé comprenant une pluralité de branches de phase (71, 72, 73), les branches de phase (71, 72, 73) étant connectables ou connectées à des conducteurs respectifs d'une pluralité de conducteurs de phase de la source d'énergie (60) portant la pluralité de phases de la puissance en CA transmise par la source d'énergie (60), chaque branche de phase (71, 72, 73) comprenant au moins une première unité commutatrice (76 ; 76, 77) commutable de manière commandée entre au moins un état conducteur et un état non-conducteur. Au moins un module de commande (80) est conçu pour mettre en œuvre une correction de facteur de puissance active en commandant la synchronisation de commutation de la première ou des premières unités commutatrices de chaque branche de phase de sorte que la forme d'onde du courant absorbé de la source d'énergie (60) par le redresseur d'entrée correspond, ou est proche de correspondre, à la forme d'onde de la tension en CA de la source d'énergie (60).
