A power conversion device according to embodiments includes a plurality of switch groups, a plurality of inductors, and a snubber circuit. The switch groups are respectively provided for input phases and each of the switch groups has a plurality of one-way switches that connects the corresponding input phase and output phases. The plurality of inductors are respectively connected between the input phases and the switch groups, and are coupled to one another so that current flowing through the one-way switch of one switch group moves to and continues to flow through the turned-on one-way switch of the other switch group when the one-way switch of the one switch group is turned off. The snubber circuit clamps a voltage based on the maximum voltage occurring on the plurality of inductors to a predetermined value. |
