并联型有源滤波器数字化控制系统的研究

Study on Digital Control System of Shunt Active Power Filter

简要分析了并联型有源滤波器基本结构和工作原理 ,提出了一种计算补偿参考电流的检测控制新方法。在此基础上建立了基于DSP的数字化控制系统 ,并进行了实验研究 ,证明了该控制系统的正确性和可行性。

This paper proposes a novel method measuring compensating reference current after it analyzes briefly the basic structure and operation principle of a shunt active power filter.Then one kind of digital control system based on DSP is set up and experiment studies are carried out.The results verify the feasibility and validity of the proposed control system.
