Abstract
An auxiliary system provide auxiliary power and air conditioning for a vehicle while a main engine of the vehicle is not operating. An auxiliary alternator is mounted to and driven directly by the drive shaft of an auxiliary engine. The auxiliary alternator has permanent magnets and three sets of windings, including two sets of windings for generating AC voltage via inverters, and a second set of windings for generating DC voltage for directly recharging a battery of the vehicle via a regulator. An air conditioner compressor also is driven by the auxiliary engine for compressing refrigerant. A condenser is in fluid communication with the compressor for condensing the refrigerant, an evaporator is in fluid communication with the refrigerant condensed by the condenser, and an electric blower moves air through the evaporator into the interior of the vehicle.
