Abstract:
First pulse width modulation control is a control of generating a first pulse width modulation signal for a plurality of switching elements by comparison of modulated waves of voltage commands in phases based on a torque command for a motor with a carrier voltage, and performing switching of the plurality of switching elements. Second pulse width modulation control is a control of generating a second pulse width modulation signal for the plurality of switching elements based on a modulation factor of a voltage and a voltage phase based on the torque command and the number of pulses per unit period of an electrical angle of the motor, and performing switching of the plurality of switching elements. An electronic control unit is configured to switch the plurality of switching elements between the first pulse width modulation control and the second pulse width modulation control at irregular time intervals.

Claim (Index 4):
The drive device according to  claim 1 , wherein\n the first pulse width modulation control is synchronous pulse width modulation control, and the electronic control unit is configured to:\n switch the plurality of switching elements from the first pulse width modulation control to the second pulse width modulation control at a time of a zero-crossing of one of the modulated waves of the voltage commands of the phases that are used to generate the first pulse width modulation signal for the plurality of switching elements; and \n switch the plurality of switching elements from the second pulse width modulation control to the first pulse width modulation control at a time of a zero-crossing time of one of modulated waves of virtual voltage commands of the phases corresponding to the second pulse width modulation signal for the plurality of switching elements.
