A Method of Measaring Compensating Reference Currentfor Active Power Filter's Control Loops

提出了一种电力有源滤波器控制回路补偿参考电流的检测方法。该方法所用乘法器少，电路实现简单，适用于单相、三相有源滤波器补偿参考电流的检测。仿真和实验结果证明了这种检测方法的有效性。

A method of measuring compensating reference current for active power filter's controllcops is presented. The method uses less multipliers and is easy to achived. It can be used in single-phase or three-phase active power filtrs'control circiuts for detecting compensating reference cur-rent. Simulation and experimental results demonstrate the validity of the proposed method.
