摘要: 有源电力滤波器的谐波检测需要优良的低通滤波器或带通滤波器。在比较了非递归数字滤波器与小波滤波器的关系之后,在利用快速傅里叶变换快速小波变换思想方法基础上,系统地给出了针对特定问题的适合于有源电力滤波器控制系统数字滤波器的设计思想和方法,最后给出了计算实例。

Abstract: Active power filter (APF) control system needs excellent lowpass or bandpass digital filter. By comparing the traditional digital filter with wavelet filter, and after analyzing the fast fourier transform fast wavelet transformation, we systematically give a series of thoughts and the methods of design digital filter specially for active power filter control system. Detailed calculation example is given also.
