摘　　要：为克服传统GAPF(generalized active power filter)实时性差、电压等级低、功耗大、只适合在低压小容量范围内应用等缺点,提出一种采用链式拓扑结构的GAPF,提高了装置的等效开关频率、电压等级、实时性和动态性能。详述了链式GAPF的拓扑结构、工作原理、控制方法及调制策略,建立了被控对象的小信号模型,给出了PI参数的整定原则和相间与相内电容电压的平衡方法。仿真与实验结果表明链式GAPF在实现综合补偿的基础上可有效降低输出电压的谐波含量和网侧滤波电抗的容量与功耗,适合在高压大功率领域中应用。In order to overcome the shortcomings of traditional GAPF which has poor real - time perform- ance, low voltage rate, high power consumption and only being suitable in low voltage and small capacity situations, a GAPF based on cascaded multilevel inverter is proposed which has higher equivalent switc- hing frequency and voltage rating, better real-time and dynamic performance. Its topology, operating principle, control method and modulation strategy were discussed in detail. The small signal model of the controlled object was established. The setting principles of proportion integration （PI） parameters and the phase and individual balancing methods of capacitor voltages were presented. Simulation and experimen- tal results show that cascaded GAPF can effectively reduce the harmonic content of output voltage and the capacity and power consumption of system side reactance while realizing comprehensive compensation, and is suitable in high voltage and power scope of application.
