摘　　要：有源电力滤波器可动态补偿电网中的谐波和无功分量。在分析整流桥直流侧并联型有源电力滤波器的基础上,提出了三相整流桥直流侧串联型有源电力滤器的基本拓扑结构,建立了基于双环控制的数学模型,并从理论上证明了基本结构和控制模型的正确性。对补偿前后三相电源电流进行了仿真研究,结果表明补偿后各相总谐波畸变率大大降低,电源电流为与电源电压同频同相的正弦波,很好地证明了该新型有源电力滤波器良好的补偿效果。The harmonic and reactive components of power network can be compensated dynamieally by active power filter （APF）. On the analysis of DC side shut APF with rectifier bridge, the basic topology of three-phase DC side series active power filter was proposed, and the mathematical model based on the dual-loop control was presented too. The correctness of the basic structure and control model was proved in theory. Simulation and analysis of the three-phase supply currents with compensation or not were proposed. The results show that the total harmonic distortion of every phase is greatly reduced with compensation and the supply currents are sine waves with supply voltages on the same frequency and same phase. The theory and simulation result prove that the novel APF can compensate effect.
