ABSTRACT

Aiming at the problem of large number of photovoltaic modules and low output voltage in photovoltaic power generation system, a multi-input high-gain DC-DC converter is proposed. The converter has multiple input-single outputs, and has the advantages of low stress of the switching device, simple control, high output voltage gain, and the number of input ports are not limited by the switching tube duty ratio. Finally, an experimental prototype with a rated power of 100W was built to verify the feasibility of the theory.
