摘要: The invention relates to an electrical subsystem power a vehicle refrigeration system. includes AC drive electrically coupled high voltage DC bus. provides 'refrigeration compressor power' responsive cooling demand. also 'low bus'. low bus powers plurality of components including fans. A microcontroller sets the and frequency. method preventing system stall step limiting such that does not droop causing stall. Also, for powering in 'V/f' operating information compressor, commands frequency compressor.
