D. Moon, J. Park and S. Choi, "New Interleaved Current Fed Resonant Converter with Significantly Reduced High Current Output Filter for EV and HEV application", IEEE International Power Electronics Conference.
Abstract : This paper proposes a new interleaved
current-fed resonant converter with significantly reduced
high current output filter which is suitable for EV and HEV
applications. The proposed interleaved converter has
theoretically zero output filter capacitance, low input
current ripple, ZCS turn on and 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 for wide input and output voltage range
operation of EV and HEV. A 2kW prototype of the
proposed converter has been built and tested to verify the
validity of the proposed operation.
