1. A series hybrid mobile refrigeration power supply system comprising:
- an engine coupled to an alternator, the alternator configured to provide an alternating current output;
a rectifier bridge coupled to the output of the alternator, the rectifier bridge configured to convert alternating current to direct current;
a distribution bus coupled to the rectifier bridge to distribute direct current to a plurality of mobile refrigeration system loads; and
a direct current compressor motor electrically coupled to the distribution bus using a contactor as a switching device, the contactor energizes the compressor motor when required by refrigeration cooling demand.
