Improvement in Efficiency of the Phase-shift Current-doubler-rectification ZVS Full-bridge DC-DC Converter

In this paper, topology exchange, together with mode exchange, is proposed to significantly improve the efficiency of the phase-shift current-doubler-rectification ZVS full-bridge Dc-Dc converter at light loads. In order to attain this purpose, a field programmable gate arrays (FPGA)-based control strategy is applied to this converter. The experimental results show that the efficiency up to 11% is upgraded at standby, as compared with the converter without the proposed method.
