大容量有源电力滤波器实现方法的研究

Study on the Implementation of Large Volume Active Power Filter

在了解当前国内外大功率有源电力滤波器发展现状的基础上 ,对实现大功率有源电力滤波器的方法进行了讨论。提出了一种以不带变压器的四重化PWM变流器为主电路的大容量有源电力滤波器的实现方法 ,给出了系统结构拓扑 ,分析了系统的控制原理。实验表明 ,该系统可以有效地解决大容量有源电力滤波器在容量和开关频率之间的矛盾。

The methods to achieve a large volume active power filter are discussed based on the status at home and abroad.The main circuit consisted of 4 multiplex using for an active power filter is introduced,and the circuit configuration and control method are given.The experiment results verify that the contradiction between frequency and volume is solved by use this method.
