摘要

针对经典单周控制有源电力滤波器（APF）存在的问题

提出了单周控制APF的双桥逆变控制策略。新控制策略的采用使其在负半周具有了正半周同样的控制效果

从而解决了经典控制策略的不足。通过Matlab/SimPowerSystem建造的模型

仿真结果显示

双桥逆变APF克服了经典单周控制APF的电流直流分量

有效地抑制了低频次谐波

增大了功率因数并实现了单周控制有源滤波器的全局稳定

同时保持了经典控制滤波器结构简单、响应迅速的特点。

Abstract

Aiming at some problems in one-cycle control of conventional active power filter（APF）

a novel one-cycle controlled APF with double-bridge is proposed.Applying double-bridge structure

APF has the same control effect in the negative half cycle as it in the positive one.Consequently

the disadvantages of conventional APF control strategy are overcome.A model is built based on Matlab/Simulink

and the simulation results reveal that the novel APF suppresses the dc component in ac current

restrains low frequency harmonics effectively

increases power factor

and achieves stability in whole cycle.Moreover

the advantages of conventional APF’s simple structure and rapid response are still held in the one-cycle controlled APF with double-bridge.
