Abstract

Cette invention concerne un dispositif de machine électrique rotative, comprenant : un enroulement de champ magnétique ; des enroulements de moteur triphasé couplés en étoile ; un onduleur possédant une pluralité d'éléments de commutation et effectuant une conversion de puissance sur la sortie de puissance provenant d'une batterie pour fournir la puissance convertie aux enroulements de moteur ; et une unité de commande configurée pour commander l'onduleur. L'unité de commande commande l'onduleur de manière à fournir du CC à l'enroulement de champ magnétique à l'aide des éléments de commutation, tandis que tous les éléments de commutation de la phase supérieure de l'onduleur effectuent la même opération et tous les éléments de commutation de la phase inférieure effectuent la même opération.
