一种谐波优化的APFC电路分析
Analysis of a Harmonic Optimization APFC Circuit
摘要
Abstract
In order to solve the problem that the traditional average current control strategy can make the APFC circuit side current contain a large number of low-order harmonic components,result in large input current distortion and the system power factor reduced significantly,a third harmonic compensation strategy was proposed.Based on the mechanism of harmonic generation in the circuit,the working principle of APFC circuit was expounded.To get the best suppression of harmonic effects,the size of the injection harmonic currents was adjusted.Finally,Matlab/Simulink was used to simulate the system and the hardware platform was built. The results show that this strategy can effectively eliminate harmonics,and further improve the power factor of grid side,it has promoted value.关键词
