High gain high power DC-DC converter for photovoltaic application

This paper introduces a novel high gain DC-DC converter topology which can be used for photovoltaic (PV) applications. The proposed DC-DC converter consists of 3 interleaved boost converters and 2 voltage multiplier cells (VMC). The operating principle, characteristic waveforms, design details along with the simulation results prove the validity of the design and its superiority over existing converter topologies in terms of its ability to provide high voltage gain at higher power level and low device stress. The proposed topology is able to produce a voltage gain of 10 and deliver 3kW output power at 88% efficiency.
