摘　　要：针对普通电流控制方法的不足 ,提出了一种基于最优瞬时电压矢量的新方法。它通过辨识最优瞬时电压矢量的区域来确定控制开关模型 ,避免了复杂计算和有源滤波器的不必要开关 ,且快速、准确 ,大力改善了有源滤波器的性能。On account of the deficiency of common current control methods, a novel control technique based on optimal instantaneous voltage vector is suggested and analyzed for active power filters (APF). It obtains switching models to control output of APF through identification of the local area of optimal instantaneous voltage vector and avoids complicated calculation and unnecessary switch of the APF. In addition, it has the advantage of high speed and good accuracy. Thus the performances of APF are improved apparently.
