A matrix converter includes a power converter and a commutator. The power converter includes a plurality of bidirectional switches provided between respective phases of an AC power source and respective phases of a load. The commutator is configured to perform commutation control by which input phases connected to output phases are switched using the bidirectional switches. The commutator includes a selector configured to select one commutation pattern from a plurality of commutation patterns based on at least one of a state of phase voltages of the AC power source and a state of phase currents of the load, and a commutation controller configured to perform commutation control by controlling the bidirectional switches pursuant to the commutation pattern selected by the selector to switch a connection state of the AC power source and the load.
