Abstract
First to third-phase converters convert first to third-phase AC voltages into DC voltages, respectively. First to third DC positive buses and first to third DC negative buses are electrically connected to the first to third-phase converters. Fourth to sixth-phase inverters convert the DC voltages into fourth to sixth-phase AC voltages. The first to third-phase converters include diode rectifiers. First to third fuses are connected between an AC power supply and the first to third-phase converters, respectively. Fourth to sixth fuses are inserted into the first to third DC positive buses, respectively. Seventh to ninth fuses are inserted into the first to third DC negative buses, respectively.
