Abstract
In some aspects of the invention, a power semiconductor module is applied to a multi-level converter circuit with three or more levels of voltage waveform. A first IGBT, a diode whose cathode is connected to the emitter of the first IGBT, and a second IGBT having reverse blocking voltage whose emitter is connected to the emitter of the first IGBT, are housed in one package, and each of the collector of the first IGBT, the collector of the second IGBT, the connection point of the emitter of the first IGBT and the emitter of the second IGBT, and the anode of the diode, is an external terminal.
