Abstract: A matrix converter includes: a power conversion unit provided between an AC power supply and a rotational machine; and a controller for performing power conversion control therebetween by controlling the power conversion unit. The power conversion unit includes multiple bidirectional switches each of which has at least one first directional switching element and at least one second directional switching element. Further, the controller includes a first drive control unit performing the power conversion by simultaneously turning on both of the first directional switching element and the second directional switching element, and a second drive control unit performing the power conversion by turning on one of the first directional switching element and the second directional switching element.
