有源电力滤波器APF的前景如何？ 通常说APF价格很贵在1000元/A左右，近期浏览相关网页看到清华姜老师开发的APF价格很低为380元/Ahttp：/江…
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 。

是不是所有的发电系统和配电系统都需要有源电力滤波器和无功发生器 谐波的危害1.使旋转电机和变压器过热、振动和噪声，降低变压器额定容量，缩短电机使用寿命2。.
有源电力滤波器APF单位主要应用行业有哪些？
有源滤波器和无源滤波器各自的优缺点 有源 滤波自身就是 谐波源。其依靠 电力电子装置，在检测到系统谐波的同时产生一组和系统幅值相等，相位相反的谐波向量，这样可以抵消掉系统谐波，使其成为正弦波形。。
请大家推荐一个有源电力滤波器厂家？ 国外品牌：ABB、施耐德、GE 平心而论，有源滤波器，如果资金不紧的话，建议选用老品牌。国外的，ABB、施耐德、GE（美国通用）。（排名不分先后）。西门子（暂时还没有听说。
