Abstract

A series hybrid power supply system for a trailer box refrigeration system is disclosed. The trailer box refrigeration system may use either a DC or an ac motor to power the compressor. The power system alternator produces power to power refrigeration system loads.

Claims

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.

2. The system according to claim 1 wherein the engine is a gasoline engine.

3. The system according to claim 1 wherein the engine a diesel engine.

4. The system according to claim 1 wherein the alternator outputs single phase ac.

5. The system according to claim 1 wherein the alternator outputs polyphase ac.

6. An electric transport refrigeration system used to cool a trailer box 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 the alternating current to direct current;

a distribution bus coupled to the rectifier bridge to distribute direct current to a plurality of electric transport refrigeration system loads;

an inverter coupled to the direct current bus, the inverter configured to invert the direct current to alternating current; and

an alternating current compressor motor electrically coupled to the inverter using a contactor as a switching device, the contactor energizes the compressor motor when required by refrigeration cooling demand.

7. The system according to claim 6 wherein the engine is a gasoline engine.

8. The system according to claim 6 wherein the engine a diesel engine.

9. The system according to claim 6 wherein the alternator outputs single phase ac.

10. The system according to claim 6 wherein the alternator outputs polyphase ac.
