摘　　要：针对有源滤波器对谐波及无功电流检测的要求，提出了一种新的谐波和无功电流的检测方法，并给出了硬件电路框图；实验结果表明，该检测方法具有电路结构简单、调试方便等特点，将之用于有源滤波器（ＡＰＦ）可同时补偿谐波和无功电流。This paper presents a new detecting approach of harmonic and reactive currents for Active PowerFilter (APF) in order to meet the demand of APF, and gives the block diagram of the detecting circuit. Theresults of experiments show that the approach has many advantages, such as simpler circuit, more convenientadjustment and so on. The approach can be used in an APF to eliminate harmonics and compensate reactive powersimultaneously.
