有源电力滤波器是一种新型的谐波及无功电流动态补偿装置,与传统的无源LC电力滤波器相比,具有响应速度快、补偿效果好、动态补偿等优点.有源电力滤波器对于电能质量的改善是未来的一个发展趋势,其中并联型有源电力滤波器的研究占主导的地位.而在我国对有源电力滤波器的研究开发还处在试验阶段,因此本文对最基础的并联型有源电力滤波器硬件电路进行了较为系统的理论和试验研究.本文介绍了有源电力滤波器的基本原理和国内外发展现状.
文中以PM15RSH120逆变芯片为中心分析了并联电压型有源电力滤波器的工作原理、直流稳压电源电源、谐波电流检测电路、PWM驱动电路等问题,并对并联型有源电力滤波器进行了设计.总结了当前几种主流谐波检测的电路,最终选择基于LA50-P电流传感器作为并联型APF的电流检测元件,详细分析了其基本原理并设计了电流信号调理电路.同时由于DSP输出的电流无法驱动APF,故设计了以75451芯片为中心的驱动电路,同时设计了相互隔离的直流稳压电源完成了有源电力滤波器的硬件系统的设计、调试.

答案

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 more 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 shunt APF current sensor as a current sensing element,a detailed analysis of its basic principle and designed the current signal conditioning circuitry.While the DSP output current can not drive APF,it was designed with 75,451 chips as the center of the drive circuit,while the design of isolated DC power supply completed APF hardware system design and commissioning.
