摘　　要：针对传统有源滤波器分频控制实现繁琐的难题,提出一种改进的有源滤波器分频闭环控制策略,与传统的分频控制策略相比,在不影响相位补偿和谐波治理效果的条件下,可以减少同步旋转坐标变换(SRCT)的次数和滤波器的数量。通过仿真实验验证了该理论的正确性,将该控制方法应用于研制的100 A容量的并联型有源滤波器实验装置,获得了良好的治理效果。Aiming at the complicated problem of frequency dividing control in active filter,an improved frequency division closed-loop control strategy for active filter is proposed.Compared with the traditional frequency-division control strategy,the proposed strategy does not affect the phase compensation and harmonic control effect,and can reduce the times of synchronous rotating coordinate transformation(SRCT)and the number of filter at the same time.The correctness of the theory is verified by simulation and experiment,and the control method is applied to the experimental device of 100 A capacity parallel type active filter developed,and good control effect is obtained.
