Claim:
1. A matrix converter, comprising: a power convertor that includes: a command generator configured to generate a control command for a PWM control on the plurality of switching elements; and a commutation controller configured to perform a commutation control on the plurality of bidirectional switches by controlling the plurality of switching elements with a commutation pattern having a plurality of steps in a case where the control command changes, wherein in a case where the control command changes during execution of the commutation control, the commutation controller executes a handover step for handover to a next commutation control and then executes the next commutation control from a step in a course of the next commutation control, and wherein the commutation pattern including the handover step is a different course of commutation control as compared to a course of commutation control executed by the commutation controller in a case where the control command does not change during execution of the commutation control.
