Solar energy is green pollution-free clean energy and has important application value in the field of photovoltaic power generation. Photovoltaic inverter UPS system that adopted two built-in high-frequency transformer models had been achieved a 12 VDC to 220 VAC power conversion through pre-DC / DC high frequency boost and post-DC / AC power frequency inverter model. This design pattern had some advantages such as simple circuit, stable performance, high energy conversion efficiency, etc.
