基于矢量谐振调节器的有源电力滤波器网侧电流检测控制方法研究

Research on Source Current Detection Type APF Control Scheme Based on Vector Resonant Regulator

基于矢量谐振调节器,提出一种全新的并联型有源电力滤波器(PAPF)网侧电流检测控制方案,该方案无需谐波分离算法,并将PAPF等效控制为串联在非线性负载与电源间的带阻滤波器,控制精度更高,且具有良好的暂态响应性能,从而以更灵活、合理的方式实现网侧谐波电流的滤除。

Based on the vector resonant regulator,this paper proposes a novel PAPF closed-loop scheme with source current detection. The novel scheme does not need the harmonics extraction algorithm and treats the PAPF as an equivalent band stop filter between the nonlinear load and the power source,which could realize better harmonics filtering performance in a reasonable way.
