摘　　要：本论文提出三相并联型有源滤波器的两种新的控制方法 ,即正弦波化控制和瞬时无功功率的控制方法。它们是基于预测瞬时电流的PWM控制。利用这种控制方法 ,既不需要瞬时功率信息 ,也不需要坐标变换 ,能够实现电流的正弦波化并能有效地消除由负载产生的瞬时无功分量 ,通过这种控制能有效地简化控制电路。In this paper, we propose and discuss two new control methods for three phase shunt APFs : the sinusoidal line current control method and the instantaneous reactive power compensation control method. They are based on a predictive instantaneous current PWM control. Neither instantaneous power information nor coordinate transformation is necessary for the control. The APF with this control scheme can eliminate effectively the instantaneous reactive component . Thereby the controller is simplified effectively.
