摘要
A matrix converter includes a selector, a commutation controller, a determinator, and a condition changer. The selector selects one commutation pattern from plurality of commutation patterns based on a state of a phase voltage of a AC power source and a state of a phase current of a load. The commutation controller performs commutation control by controlling bidirectional switches pursuant to the commutation pattern selected by the selector to switch a connection state of the AC power source and the load. The determinator determines a power loss generated by the commutation control in the bidirectional switches. The condition changer changes 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.
