Claim:
1. A three-level power converting apparatus comprising: a power conversion circuit for one phase that selects potential of any one of an upper-side direct-current terminal, an intermediate potential terminal, and a lower-side direct-current terminal and outputs the potential to an alternating-current terminal; the power conversion circuit includes: when outputting the potential of the intermediate potential terminal to the alternating-current terminal, the three-level power converting apparatus controls the MOSFETs of the second, third, fifth and sixth switching elements to be turned on simultaneously, and an electric current is simultaneously fed to the MOSFET, the body diode of the MOSFET and the diode element included in the fifth switching element and to the MOSFET, the body diode of the MOSFET and the diode element included in the sixth switching element.
