An estimation section estimates a time period required for a norm of a difference vector between a current flowing to a motor/generator and a command current to attain a threshold level r in each switching mode provisionally set by a mode setting section. A mode determination section determines the switching mode of the longest required time period to be a final switching mode. A drive section controls an inverter to operate in the switching mode determined by the mode switching section.
