摘要: A controlling/driving apparatus for an electrically-driven compressor of air conditioner mounted in automobile. The comprises a DC-AC converting invertor 4 DC voltage into pseudo AC (e.g. pulse train positive and negative pulses), detector 7, width changing unit 8 the each accordance with detected by detector. Thus, enables safe efficient operation improved electric insulation durability when large fluctuations power source occur.
