Abstract:
A power conversion device includes a plurality of leg circuits and a control device. The plurality of leg circuits correspond to respective phases of an AC circuit and connected in parallel between common first and second DC terminals. Each leg circuit includes a plurality of chopper cells each including an energy storage and cascaded to one another and at least one inductance connected in series to the plurality of chopper cells. The control device controls an operation of only at least one chopper cell included in each leg circuit based on a circulating current which circulates through the leg circuits.

Claim (Index 17):
A power conversion device which converts power between a DC circuit and an AC circuit, the power conversion device comprising:\n a plurality of leg circuits which correspond to respective phases of the AC circuit and are connected in parallel between common first and second DC terminals, each leg circuit including:\n a plurality of converter cells of a half bridge type each including an energy storage and cascaded to one another; and \n at least one inductance connected in series to the plurality of converter cells; and \n a control device which controls operations of the plurality of converter cells of each leg circuit, the control device configured to:\n control at least one converter cell included in a leg circuit to control a circulating current which flows through the leg circuit; and \n control another converter cell included in the leg circuit not to control the circulating current which flows through the leg circuit and to control a current other than the circulating current which flows through the leg circuit.
