摘要
Abstract
The power factor correction circuit usually adopts double loop PI control,which has the problems of poor dynamic response performance of output voltage and large distortion of input current.Aiming at such problems,a power factor correction circuit with current loop duty cycle compensation and voltage loop fuzzy control is designed.Aiming at the problem of current distortion,a PFC circuit with duty cycle compensation is designed.In order to further improve the stability of the output voltage and reduce overshoot,the outer loop is controlled by fuzzy PI control.Finally,the simulation model is built by Matlab/Simulink.The simulation results show that the total harmonic distortion rate of the input current of the improved PFC circuit is reduced,and the output voltage overshoot is reduced,which improves the power supply quality of the power grid and reduces the harmonic pollution.关键词
