Abstract
A refrigerated cargo vehicle has a refrigerated enclosure and a refrigeration system that delivers a refrigerated air flow to the enclosure. The refrigeration system includes a compressor that has a voltage rating higher than the electric potential output of an alternator driven by an engine of the refrigerated cargo vehicle. A DC-to-DC power converter is disposed electrically between the alternator and the compressor so that the power converter receives electric current from the alternator at a first electric potential and outputs a second electric current to the compressor at a second electric potential higher than the first electric potential.
