PROBLEM TO BE SOLVED: To enable a power conversion system to make power conversion by using a motor and a plurality of DC power sources, without increasing the physical constitution or weight of the motor. SOLUTION: A motor 400 is a three-phase motor provided with u-, v-, and w-phase stator windings in a stator. Each of the stator windings is constituted by connecting two windings in series and both the windings constitute high- voltage windings. Of the two windings constituting the high-voltage windings, the winding nearer to the midpoint of a Y-connection also constitutes a low- voltage winding. A high-voltage inverter 300 is connected between a high-voltage battery 200 and the motor 400, and in particular, the motor 400 side of the inverter 300 is connected to the u-, v-, and w-phase high-voltage windings. A low-voltage inverter 500 is also connected between an low-voltage battery 600 and the motor 400, and particularly, the motor 400 side of the inverter 500 is connected respectively to the u-, v-, and w-phase low-voltage windings. |
