A power conversion device includes: a bridge circuit in which a switch element is provided in each of plural arms; a filter that is provided on an alternating current side of the bridge circuit, and connected to a neutral point; a reactor provided between the bridge circuit and the filter; a smoothing circuit provided on a direct current side of the bridge circuit; a snubber circuit provided between the bridge circuit and the smoothing circuit; and a switch circuit provided between the smoothing circuit and the snubber circuit. The smoothing circuit includes two smoothing capacitors connected in series between a positive line and a negative line, and the neutral point is connected between the two smoothing capacitors. The snubber circuit includes two snubber capacitors connected in series between the positive line and the negative line, and the neutral point is connected between the two snubber capacitors. The switch circuit includes a first switch provided on the positive line and a second switch provided on the negative line. |
