ABSTRACT:
A distributed staged power system for use in electric and hybrid electric vehicles, and the like. The system comprises a plurality of parallel DC-to-DC power modules that are controlled by way of input and output control signal interfaces using a smart controller. The distributed staged power system provides higher efficiency because of smart staging of the power modules. The distributed staged power system enables or disables each of the modules as determined by a smart controller to provide the highest possible conversion efficiency.
