摘　　要：介绍了并联型有源电力滤波器(APF)的基本原理,双重化的主电路结构和SPWM多重化原理,以及APF的谐波提取及其控制策略。为了提高有源电力滤波器的容量及其谐波补偿效果,采用了载波移相双重化技术,在不提高逆变桥的开关频率与保持主电路拓扑结构的前提下获得高的等效开关频率,还可减少系统输出的高次谐波含量。实验结果表明:基于DSP的双重化有源电力滤波器具有很好的补偿效果。This paper introduced the fundamental of the shunt active power filter （APF）,the main circuit topology of the dual power filter,the principle of multiple-SPWM,the harmonic extraction of APF and its relevant controlling strategy.To enhance the capacity of the active power filter as well as the harmonic compensation effects,this paper utilizes the dual technology of carrier wave shifting,and this measure can obtain increased equivalent switch frequency without the alteration in main circuit topology and augmentation in the switch frequency of the inverter bridge,which also can curtail the ultra-harmonics of the system output.The experimental results denoted that the dual APF based on the DSP controller can generate significantly compensatory effect.
