有源电力滤波器的基本原理是怎样的？能通俗些最好。 有源滤波器本质上相当于一个变频器（也可称变流器），其作用是产生与谐波幅值相当，相位相反的电压信号（并联型有源滤波器），与电网谐波进行叠加，叠加后谐波被大幅度抑制。
有源电力滤波器由哪些主要部件构成？ 德殷有源滤波器主要由接触器、断路器、继电器、电流传感器、限流电阻、LRC高频滤波电路、IGBT、IGBT电桥、驱动器、浪涌缓冲器、熔丝、风机、电抗器等等。
英语翻译 APF is a new dynamic harmonic and reactive current compensation device，with the traditional passive LC power filter compared with a fast response，the compensation effect，dynamic compensation and other advantages.Active power filter for power quality improvement is a developing trend in the future，which Shunt Active Power Filter dominant position.In China for research and development of active power filter is still in experimental stage，so this article on the most basic of shunt active power filter hardware circuit for a systematic theoretical and experimental research.This article describes the basic principles of APF and development in the world.Text to PM15RSH120 inverter chip-centric analysis of the shunt voltage active power filter works，DC power supply，harmonic current detection circuit，PWM driver circuit and other issues，and the shunt active power filter the design.Summarizes the current several mainstream harmonic detection circuit，the final selection is based on LA50-P 。
