Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/235257
Kind Code:
A1
Abstract:
First to third phase converters (2R, 2S, 2T) convert first to third phase AC voltages to DC voltages, respectively. First to third DC positive bus lines (PL1, PL2, PL3) and first to third DC negative bus lines (NL1, NL2, NL3) are electrically connected to the first to third phase converters (2R, 2S, 2T). Fourth to sixth inverters (3U, 3V, 3W) convert the DC voltages to fourth to sixth phase AC voltages. The first to third phase converters (2R, 2S, 2T) include diode rectifiers. First to third fuses (FR, FS, FT) are respectively connected between an AC power supply and the first to third phase converters (2R, 2S, 2T). Fourth to sixth fuses (FP1, FP2, FP3) are inserted in the first to third DC positive bus lines (PL1, PL2, PL3), respectively. Seventh to ninth fuses (FN1, FN2, FN3) are inserted in the first to third DC negative bus lines (NL1, NL2, NL3), respectively.
