Zusammenfassung:	A three-level I-type inverter includes first to fourth switching devices between first and second potentials, first to fourth diodes, and fifth and sixth diodes. The first to fourth diodes are respectively connected to the first to fourth switching devices in anti-parallel. Between a connection node of the first and second switching devices and a connection node of the third and fourth switching devices, the fifth and sixth diodes are connected in series and in anti-parallel with series connection of the second and third switching devices. A connection node of the fifth and sixth diodes is connected to an input node having intermediate potential. A connection node of the second and third switching devices is connected to an output node. The second switching device and diode are formed of a first reverse conducting IGBT. The third switching device and diode are formed of a second reverse conducting IGBT.
