摘　　要：针对改进型DC侧APF具有负载输出电压可调、控制和驱动简单、储能电容容量小等优点,依据单相改进型拓扑,提出一种三相改进型DC侧APF拓扑模型,对三相整流类负载进行谐波治理具有技术优势。与三相PFC相比,该拓扑仅处理部分功率,主电路结构简单;与交流侧APF相比,简化了电路结构,减少了功率开关数量。仿真结果证明了该拓扑的正确性和可靠性。As the improved DC side active power filter（APF） is characterized by adjustable load output voltage,simple control and drive,small storage capacitance etc.,this paper proposes an improved three-phase DC side APF topology model based on an improved single-phase topology,which has great technical advantages of harmonic elimination for three-phase rectifier load.Compared with the three-phase power factor correction（PFC）,the proposed topology only processes part of power and the main circuit structure is simple;compared with the AC side APF,the circuit structure is simplified and the amount of the power switches is reduced.The simulation results show that this topology has high accuracy and reliability.
