Abstract
At the time of charging a power storage device from a commercial power supply, electric power from the commercial power supply is applied to a neutral point of each of first and second motor generators. A rotation preventing control unit () determines one phase to be subjected to switching control in the first inverter, based on a rotation angle (θ) of the first motor generator. Further, rotation preventing control unit () calculates torque generated in the first motor generator, generates a torque control value for canceling out the torque, and outputs the value to a phase voltage operating unit () for motor control.
