A power conversion device equipped with: a bridge circuit the multiple arms of which are provided with a respective switch element; a filter provided on the alternating-current side of the bridge circuit and connected to a neutral point; reactors provided between the bridge circuit and the filter; a smoothing circuit provided on the 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-electrode line and a negative-electrode 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-electrode line and the negative-electrode line, and the neutral point is connected between the two snubber capacitors. The switch circuit includes a first switch, provided on the positive-electrode line, and a second switch, provided on the negative-electrode line. |
