More Information
Summary:A power conversion device according to the present disclosure includes: a DC/DC conversion unit including positive and negative legs composed of semiconductor switching elements connected in series, an output filter having magnetic energy storage elements connected to output ends of the legs and first and second electric energy storage elements connected in series and having a neutral point, first and second current detection units, and a voltage detection unit; and a control unit composed of a single output voltage control unit which outputs a current command value, and first and second current control units which generate gate signals on the basis of the current command value and detection current values, to control ON/OFF operations of the semiconductor switching elements, independently of each other.
