Saber simulation and experimental study on single-phase power factor correction circuit

In order to solve the problem of serious harmonic pollution and power factor decline caused by uncontrolled rectification of the power electronic devices, an active power factor correction method based on UC3854 chip is proposed. The simulation model on the Saber software simulation platform is set up. Simulation results show that the power factor reaches more than 0.99. The system hardware circuit is constructed and the experimental results are basically the same as those of the simulation. Moreover the rationality and superiority of the circuit are verified.
