摘要：

为了提高电网的电能质量,使用有源电力滤波器（APF）对谐波电流进行补偿是常用方法之一。非线性负载不控整流产生的畸变电流具有很高的变化率。双极性调制的单相全桥拓扑采用传统单周控制方法时,由于APF的补偿电流无法及时变化,导致了电网电流在电流突变时刻存在畸变。本文提出了一种采用负载电流微分补偿的方法,改善了负载电流突变时刻的补偿效果。分析了补偿原理并提出了实现方法,利用Matlab/Simulink进行仿真,并证明了该方案能够明显降低电网电流畸变。

Abstract:

To improving the electric power quality, active power filter (APF) is commonly used. The distorted current, which is produced by non-linear load, has a steep change due to uncontrolled current rectification. Implementing classical one-cycle-control scheme, The dual-polarity modulated Single-phase full-bridge is hardly to gain enough current to compensate the distortion current of non-linear load. The load current derivative compensation scheme is proposed to improve the performance of APF. Theatrical analysis and implement schematic are presented. Using Matlab/Simulink, the result of simulation shows that the total harmonic will greatly reduced.

Key words: Active power filter, single-phase full-bridge converter, one cycle control, load current derivative compensation
