Abstract:
Each of a plurality of specified chopper cells which are some of a plurality of chopper cells included in each leg circuit in a power conversion device is configured as a full bridge. A control device controls operations of first and second switching elements of each specified chopper cell based on a circulating current which circulates through each leg circuit. The control device controls operations of third and fourth switching elements of each specified chopper cell based on a voltage of a capacitor of the specified chopper cell.

Claim (Index 1):
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,\n each leg circuit including:\n a plurality of converter cells cascaded to one another and each including an energy storage; and \n at least one inductor connected in series to the plurality of converter cells, \n \n each of a plurality of specified converter cells which are some of the plurality of converter cells included in each leg circuit including:\n a capacitor as the energy storage; \n first and second switching elements connected in parallel to the capacitor and connected in series to each other; and \n third and fourth switching elements connected in parallel to the capacitor and connected in series to each other, \n \n the capacitor being capable of being charged and discharging through a connection node of the first and second switching elements and a connection node of the third and fourth switching elements; and \n a control device which controls operations of the plurality of converter cells included in each leg circuit, the control device controlling operations of the first and second switching elements of each specified converter cell based on a circulating current which circulates through each leg circuit, the control device controlling operations of the third and fourth switching elements of each specified converter cell based on a voltage of the capacitor of each specified converter cell.
