Abstract

A three-level converter includes a switch circuit including first to fourth switch groups with n switches. A boot diode connected to a drive circuit to drive a switch on a lowest voltage side of a second switch group includes a cathode to which an anode of another boot diode of the second switch group is connected. A boot diode connected to a drive circuit to drive a switch element on a lowest voltage side of a third switch group includes a cathode to which an anode of another boot diode of the third switch group is connected. A boot diode connected to a drive circuit to drive a switch on a lowest voltage side of a fourth switch group includes a cathode to which an anode of another boot diode of the fourth switch group is connected.
