要約(英語): A single-stage reconfigurable isolated DC/DC converter(1) is proposed for use in hybrid and electric vehicles (EVs and HEVs) to supply a 12V automotive network from the HV battery. The purpose of the proposed topology is to increase the converter efficiency at the higher voltage range of the HV battery. A zero voltage transition (ZVT) phase shift (PS) full bridge (FB) converter is the basis for the reconfigurable topology, which is adapted to operate as a push-pull converter. The ZVT PS FB configuration covers the upper range of input voltages, in which an increased converter efficiency has more effect. It is furthermore reconfigured into the less efficient, hard-switching, push-pull configuration to cover the lower, less significant voltage range. The reconfiguration voltage is chosen to maximize the average efficiency according to the histogram of the HV-battery voltage during a typical driving cycle. Experimental validation of the proposed converter and its efficiency improvement are also presented.
