1. A matrix converter, comprising:

  • a power converter including a plurality of bidirectional switches provided between respective phases of an AC power source and respective phases of a load;

    a selector configured to select one commutation pattern from a plurality of commutation patterns based on a state of a phase voltage of the AC power source and a state of a phase current of the load;

    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;

    a determinator configured to determine a power loss generated by the commutation control in the bidirectional switches; and

    a condition changer configured to change the commutation patterns which become a selection target of the selector or a selection condition of the commutation patterns which become the selection target of the selector, based on the power loss determined by the determinator.
