Research on Active Power Filter Based on DSP

提出有源滤波器的原理并实现了一种基于数字信号处理器(Digital Signal Processor,简称DSP)的有源电力滤波器装置,给出了主电路及信号检测电路的组成,该电路可满足DSP及其控制算法对电路结构及信号的要求。通过实验证明系统具有良好的跟踪补偿特性,使谐波得到了抑制,保证电网波形接近正弦波,较好地达到了设计要求。

The principle and realization of the active power filter based on DSP are introduced. At the same time, the main circuit and signals detection circuit are also provided. The experimental shows that the system has good dynamic compensation characteristics and has reached the design goals. Also, the harmonic in power system is restrained and the power waves are close to the sine wave.
