High Voltage Air Conditioning Compressor Drive
In conventional vehicles the air conditioning compressor is powered through a belt system by the internal combustion engine. But in HEV and EV vehicles the internal combustion engine cannot be relied upon to be always available to provide power to auxiliary loads, while the car air conditioning system is expected to operate at all times. Therefore in these vehicles the air conditioning compressor is driven by an inverter from the high voltage battery. This motor drive also allows the power consumption of the compressor to be optimized, improving overall fuel efficiency.
