Abstract
A matrix converter according to an embodiment includes a control unit generates a highest phase-to-phase voltage among load side phase-to-phase voltages by controlling bidirectional switches that connect phases with respect to the highest phase-to-phase voltage and phases with respect to a highest phase-to-phase voltage among AC-source side phase-to-phase voltages. Moreover, the control unit generates a middle phase-to-phase voltage among the load side phase-to-phase voltages by controlling bidirectional switches that connect phases with respect to the middle phase-to-phase voltage and phases with respect to a middle phase-to-phase voltage among the AC-source side phase-to-phase voltages.
