本文提出了一种新的控制方法，适用于有源电力滤波器，以减少与三次谐波电流补偿相关的直流电容电压纹波。该方法在补偿电流上叠加负序基波电流，以抵消三次谐波电流引起的有功涟漪。因此，该方法具有消除直流电容电压纹波的能力，在两倍的源频率。10 kW三相二极管整流器的实验结果验证了该方法的有效性。所提出的方法具有良好的抑制性能的直流电容电压涟漪在两倍的源频率。
This paper proposes a new control method suitable for active power filters to reduce the dc capacitor voltage ripples associated with the third-order harmonic current compensation. The proposed method superimposes a negative-sequence fundamental current on the compensating current to cancel out the active power ripple caused by the third-order harmonic current. As a result, the proposed method has the capability to eliminate the dc capacitor voltage ripple at double the source frequency. Experimental results obtained by a 10-kW three-phase diode rectifier verify the validity of the proposed method. The proposed method exhibits a good suppression performance of the dc capacitor voltage ripple at double the source frequency.
