一种带前馈的双闭环APFC控制方法
A double closed loop APFC control with feed-forward
摘要
Abstract
In order to improve the steady state performance,dynamic response and power factor of traditional power factor correction (PFC) digital control method and reduce the harmonic distortion of input current,a double closed loop active power factor correction (APFC) control method with feed-forward is proposed.Firstly,the small signal model of Boost PFC control system is built and the system transfer function is deduced,and then the parameters of the main device with Boost topology is estimated.By means of the feed-forward,the system can quickly respond to the change in input voltage.Furthermore,the use of voltage loop and current loop can achieve input current and output voltage regulation.Simulink modeling shows that this method can effectively control the output voltage in case of input voltage largely fluctuating,improve the system dynamic response ability and input power factor,and reduce the input current harmonic distortion.关键词
