摘　　要：针对单相并联电压型有源电力滤波器(APF),提出了一种改进的无差拍电流控制方法。在采样过程中,以前一周期的采样值为参考值,利用自适应谱线增强器(ALE)预测下两个采样周期APF的补偿误差,使实际输出的补偿电流准确跟踪参考值,从而达到实际输出电流和参考电流误差为零的目标。通过DSP实验证明了改进的无差拍电流控制方法的可行性和有效性。Aiming at the single phase shunt voltage active power filter（APF）,this paper raised an improved deadbeat current control method.In the process of sampling,the former sampling value was taken as reference and the compensation errors of APF for next two sampling cycles were predicated by using adaptive line enhancer,which made actual output compensation currents tail after reference value correctly,thus to reach the goal of zero error between actual output current and reference current.DSP experiments prove the feasibility and validity of the improved deadbeat current control method.
