Interleaved resonant power converters for renewable energy systems

This paper develops an interleaved resonant power converters for renewable energy systems such like photovoltaic (PV), energy storage system discharging and fuel cell. The renewable application requirements are high voltage gain, reduce input current ripple and overall converter size and high efficiency. The active power switches and energy blocking diode operated at zero voltage switching (ZVS) and zero current switching (ZCS) which can boost overall efficiency of interleave converter. The principle operation of the proposed interleave resonant power converter is expressed by detailed mathematical analysis. Performance of the proposed interleave resonant power converter is validated through simulation results in MATLAB.
