The design of single-phase variable frequency power supply with APFC

Around the above problem, the new power supply is designed. In the design, L6562 is used to control the APFC circuit, and EG8010 is used to control full-bridge inverter circuit. According to the design requirements, firstly, the parameter calculation and the device selection are completed. Then, Saber software is used to simulate the active power factor correction circuit and the inverter circuit. At the same time, the parameters of input power factor and output load regulation rate are calculated to validate the rationality of the calculated devices and the feasibility of the design circuit. At last, the hardware circuit is built and tested. In a word, the designed power supply is available and efficiency, because it can not only achieve the function of changing frequency, but also have the result of power factor correction.
