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 23):
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, each leg circuit including a plurality of converter cells each including an energy storage; and a control device which controls an operation of at least one of the plurality of converter cells, the control device generating a voltage command value for controlling the at least one converter cell by linearly combining a value based on a difference between a circulating current which circulates through the leg circuit and a circulating current command value with a voltage command value of a remaining converter cell of the plurality of converter cells.
