摘要
This power converter (1) is provided with: unit cells (11-M) having a semiconductor switch, a DC capacitor (C) and a charge/discharge current I/O terminal; a first arm (12-P) and a second arm (12-N) comprising multiple unit cells (11-M) connected to each other in cascade; an arm connecting unit (13) which has a first terminal to which the first arm (12-P) is connected, a second terminal to which the second arm (12-N) is connected, and a third terminal to which a DC power source is connected; and a transformer (14) which has an AC I/O terminal on the primary side and an intermediate terminal on the secondary side winding, and in which the terminal of the first arm (12-P) and the terminal of the second arm (12-N) are connected to the two end terminals on the secondary winding, and the DC power source (Vdc) is connected to the intermediate terminal.
