摘要
为解决大容量有源电力滤波器(APF)容量与开关频率间的矛盾,给出一种新型双频控制大功率电流型APF。该拓扑由一个低频大功率电流型变流器(主变流器)和一个高频小功率电流型变流器(副变流器)并联组合而成。其工作原理是将负载谐波电流分解为大幅值低频段谐波和小幅值高频段谐波,分别由主、副变流器进行补偿控制。仿真和实验表明该新型APF具有控制简单、开关损耗低、输出谐波含量小等优点。
In order to solve the contradiction between the volume and switch frequency in active power filter（APF）, a novel high power current source APF based on dual frequency control technology is presented and analyzed.The topology consists of two inverter,a low frequency high power current source inverter（master inverter） and a high fre- quency low power current source inverter（slave inverter） in parellel.The load harmonic current is decomposed into a low frequency but large amplitude and a high frequency but small amplitude harmonic curve, they are controlled by master and slave inverter.Simulation and experimental results show that the new APF has many advantages,such as low output distortion, low switching loss and simple control.
