Abstract:
1. A power converting apparatus comprising: a power converter that includes a plurality of unidirectional switches which connect input phases and output phases, and that includes a plurality of switch groups each being provided for one of the input phases, and a plurality of inductors coupled to one another such that current flowing in a winding of a first inductor of the plurality of inductors moves to a second winding in a second inductor of the plurality of inductors with the magnitude of the current maintained, each of the inductors of the plurality of inductors being connected between one of the input phases and a corresponding one of the switch groups; and a controller that includes a first signal generator which generates switch drive signals for AC-to-DC conversion, a second signal generator which generates switch drive signals for DC-to-AC conversion, and a drive signal generator which generates, in accordance with the switch drive signals for AC-to-DC conversion and the switch drive signals for DC-to-AC conversion, switch drive signals for controlling on and off of the plurality of unidirectional switches, the first signal generator and the second signal generator operating in synchronization with each other.
