Abstract
Aspects of the invention are related to a power semiconductor module applied to a multi-level converter circuit with three or more levels of voltage waveform. Aspects of the invention can include a first IGBT to which a diode is reverse parallel connected 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, and the connection points of the emitter of the first IGBT and the emitter of the second IGBT, is an external terminal.
