Abstract
This paper proposes a new interleaved current-fed resonant converter with significantly reduced high current side output filter. The proposed interleaved converter has theoretically zero output filter capacitance, low-input current ripple, ZCS turn-on and turn-off for all switches and diodes, and zero di/dt at turn-off of diodes when operated at load independent points. A two-stage power conversion technique is applied to the interleaved converter for high efficiency under wide voltage range operation. A 2-kW prototype of the proposed low-voltage dc/dc converter for EV and HEV applications is built and tested to verify the validity of the proposed operation.
