MOTOR-DRIVING APPARATUS CAPABLE OF CHARGING VEHICLE BATTERY

摘要

An object of the invention is to provide a motor-driving apparatus capable of charging a vehicle battery easily by using plurality types of grid voltages. The motor-driving circuit having a DC/DC converter capable of charging a vehicle battery consisting of two sub batteries selects either one of parallel connection and series connection of the two sub batteries. Further, the motor-driving circuit has at least one multi-phase power converter having a plurality of legs connected in parallel. The multi-phase power converter constitutes a half bridge of a full-bridge rectifier for rectifying an alternative voltage supplied by an outer battery charger.
