Provided is an inexpensive and small-size power conversion device in which a high-cost and large-scale reactor such as a buffer reactor can be eliminated. The power conversion device has: a plurality of switching elements (21u, 21x) for performing conversion between DC and AC by switching; a unit (C) including the switching elements (21u, 21x) and a capacitor (30); and unit arms (10P, 10N) each including at least one unit (C). The primary side of a transformer (40) is connected between the pair of unit arms (10P, 10N) so that short-circuit current is suppressed by a leakage inductance component. |
