A power converter (1) is equipped with three AC input terminals provided per phase on the three-phase AC input side, a reactor connected to each of the AC input terminals, one AC output terminal provided per phase on the three-phase AC output side, and a cluster constituted by connecting single-phase full bridge converters in cascade, wherein the clusters connected to the AC input terminals provided to different phases are provided so as to be connected to the same AC output terminal. The power converter (1) comprises: a circulating current control unit (11) for controlling the circulating current circulating within the power converter (1) to follow a predetermined circulating current command value; an AC input/output current control unit (12) for controlling the current on the three-phase AC input side to follow an AC input current command value and controlling the current on the three-phase AC output side to follow an AC output current command value; and an effective power control unit (13) for controlling an all DC capacitor voltage average value to follow a predetermined DC capacitor voltage command value, said all DC capacitor voltage average value being obtained by averaging the voltages across all DC capacitors within the power converter (1). |
