Abstract: With the depletion of fossil fuels and the aggravation of environmental pollution, solar energy, as an inexhaustible
clean energy, is favored by human beings. Photovoltaic power generation is one of its typical applications. As we all know, solar
energy is easily affected by weather, light, temperature, season and geographical location, which leads to the instability of power
generated by photovoltaic panels. In order to solve the problem of instability of photovoltaic power generation, it is needed to add
photovoltaic inverter in photovoltaic power generation system. In this paper, a photovoltaic inverter with interleaved flyback was
designed. The circuit topology can be divided into DC/DC converter and DC/AC inverter. The inverter circuit has the advantages
of simple structure, safety and stability, good electrical performance and low cost. The system simulation and prototype test verify
the scientificity of the design.
