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。
电力有源滤波器传统的交流直流指的是什么呢？ 电力有源滤波器传统的交流直流(ACDC)变换器在投运时，将向电网注入大量的谐波电流，引起谐波损耗和干扰，同时还出现装置网侧功率因数恶化的现象，即所谓“电力公害”，例如。
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 。
