A matrix converter includes: a power conversion unit that includes a plurality of bidirectional switches; and a control unit configured to control the plurality of bidirectional switches. The control unit includes: a first commutation control unit configured to perform a commutation control with a first commutation method; a second commutation control unit configured to perform a commutation control with a second commutation method different from the first commutation method; and a selection unit configured to select a commutation control unit that is configured to execute a commutation control from the first commutation control unit and the second commutation control unit based on any one of a phase of an output electric current) from the power conversion unit and a phase of an input voltage to the power conversion unit.
