[PROBLEMS] To obtain a controller capable of enhancing generation torque of an AC motor. [MEANS FOR SOLVING PROBLEMS] A controller for driving an AC motor through an inverter based on two or more power supplies including an energy storage element comprises a first inverter for converting a DC electricity supplied from the outside to an AC electricity, a power supply for storing the DC electricity, a second inverter for converting the DC electricity supplied from the power supply to an AC electricity, and an adder for adding AC voltages on the output side of the first and second inverters.
L~invention concerne un module de commande permettant d~améliorer le couple généré par un moteur à courant alternatif. Le module de commande selon l~invention excite le moteur à courant alternatif via un onduleur en fonction d~au moins deux alimentations, notamment d~un élément de stockage d~énergie. Il comprend un premier onduleur servant à convertir un courant continu fourni de l~extérieur en un courant alternatif, une alimentation servant à stocker le courant continu, un deuxième onduleur servant à convertir le courant continu fourni par l~alimentation en un courant alternatif, et un additionneur servant à ajouter les tensions alternatives à la sortie des premier et deuxième onduleurs.
