ABSTRACT:
Distributed staged power systems and control methods for use in supplying power to a load of electric and hybrid electric vehicles. The systems comprise a plurality of parallel DC-to-DC power modules whose output power is controlled in accordance with the various control methods. The distributed staged power systems provide higher efficiency because of smart staging of the power modules. The control methods enable or disable selected power modules as determined to provide the highest possible power conversion efficiency.
