Abstract
In the present invention, when the number of storage batteries (31-33) that are in electrical continuity with a high-voltage power supply line (H1) is changed due to respective switches being switched, an inverter control unit (100) controls an inverter (20) so that a voltage that is inputted to a motor (10) and to the inverter is stepped up or down by the motor and the inverter, and so that the inter-terminal voltage of a first smoothing capacitor (21) is adjusted.
