A power conversion device in which a plurality of semiconductor modules is connected in parallel unifies and reduces surge voltages resulting from parasitic inductances at the time of switching. The device includes first and second capacitors 102,103, and first and second semiconductor modules 108, 109. The positive terminals of the first and second capacitors and positive terminals of the first and second semiconductor modules are connected by positive wiring 201. Negative terminals of the first and second capacitors and negative terminals of the first and second semiconductor modules are connected by negative wiring 202. The first capacitor is connected to first ends of the positive wiring and the negative wiring via the positive terminal and the negative terminal and the second capacitor is connected to second ends of the positive wiring and the negative wiring via the positive terminal and the negative terminal. The first and second semiconductor modules are connected by the positive wiring via the positive terminals and connected by the negative wiring via the negative terminals in areas between the first ends and the second ends of the positive wiring and the negative wiring. The arrangement is particularly suitable for a railway vehicle.
