摘要： A power conversion device (1, 1A, 1B), which limits a zero-phase current without using a reactor, includes clusters (12uv, 12vw, and 12wu) in each of which six unit cells (121) are connected in series; and a transformer (11) that has legs (113uv, 113vw, 113wu) on each of which a primary winding (111uv, 111vw, 111wu) and a secondary winding (112uv, 112vw, 112wu) are wound for magnetic coupling. The both ends of the secondary winding (112uv, 112vw, 112wu) are connected to the both ends of the cluster (12uv, 12vw, 12wu).
