A first pair including a highest-outer-side switching element and a switching element that operates as a neutral clamp diode on a higher potential side, a second pair including a lowest-outer-side switching element and a switching element that operates as a neutral clamp diode on a lower potential side, and a third pair including a higher-inner-side switching element and a lower-inner-side switching element are respectively configured from power modules that are two-element-inclusive power modules, a power conversion circuit portion being configured from the first pair, the second pair, and the third pair. |
