Abstract[English]
A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a first decoupling capacitor configured to be connected to a positive connection of the battery and a negative connection of the battery; and a first power module including: a first upper phase switch configured to control a first upper phase flow of current between the positive connection of the battery and a first phase connection of the motor, and a first lower phase switch configured to control a first lower phase flow of current between a negative connection of the battery and the first phase connection of the motor.[French]
La présente divulgation concerne un système qui comprend : un onduleur configuré pour convertir une puissance CC d'une batterie en puissance CA pour entraîner un moteur, l'onduleur comprenant : un premier condensateur de découplage configuré pour être connecté à une connexion positive de la batterie et une connexion négative de la batterie ; et un premier module de puissance comprenant : un premier commutateur de phase supérieure configuré pour commander un premier flux de phase supérieure de courant entre la connexion positive de la batterie et une première connexion de phase du moteur, et un premier commutateur de phase inférieure configuré pour commander un premier flux de phase inférieure de courant entre une connexion négative de la batterie et la première connexion de phase du moteur.
