| 摘 要： | 无变压器并联混合型有源电力滤波器是一种新颖的有源滤波器拓扑结构.阐述系统主电路组成,给出无源部分的设计原则,提出将带有校正环节的复合控制和直流侧电容电压控制引入控制环路以获得指令电流的控制策略,继而通过三角载波控制实现实际输出电流对指令电流的跟踪.在Matlab环境下建立系统模型并进行仿真.仿真结果表明,应用该控制策略的滤波器可以有效地对负载谐波进行补偿,从而证明该控制策略的可行性.

| Abstract: | Transformerless shunt hybrid active power filter(TLS-HAPF) is a novel topology of APF.This paper gives the principle of PF and APF design in TLS-HAPF,proposes a kind of composite control mode which is composed of load current detecting control mode and source current detecting control mode,and introduces capacitor voltage control into the control circuit,at the end use a triangular waveform of 10 kHz to produce PWM.A model of TLS-HAPF is established and simulation has come out in Matlab,the result shows this topology improved the power quality effectively. |
