Abstract

The design of high reliability, high efficiency, high power factor and low cost is the development trend of the current switching power supply. Traditional switching power supply, input current of rectifier filter circuit, which contains a large number of harmonics, will cause the power utilization efficiency decreased, low power factor and so on. In this paper, flyback topology with capacitor-less is used. The flyback switching converter controlled by ARM is designed for power factor correction, and its working principle is analyzed in detail. It can reduce the impact of high input ripple voltage caused by capacitor-less on the output voltage ripple and achieve constant current source, and to obtain high power factor by using program algorithm. Matlab/Simulink is used to verify the design, and the simulation results show that the scheme is feasible.
