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 4):
The power conversion device according to  claim 1 , wherein the control device calculates a difference between a representative value of capacitor voltages of the plurality of specified converter cells and a command value of the capacitor voltage for each leg circuit, and controls operations of the third and fourth switching elements of each specified converter cell based on a result of multiplication between a value obtained by amplification of the calculated difference and a DC current value from the DC circuit or a polarity of the DC current value.
