摘要
针对空间矢量最优控制、定频滞环电流控制、单周控制、变结构控制等几种目前在有源电力滤波器(APF)控制中较新、应用较广的方法进行了对比分析,指出了它们各自的优缺点及应用范围提出了基于单位功率因数(UPF)控制和组合变流器相移SPWM两种控制策略。
The novel spare vector modulation, one-cycle control, variable structure control, multi-modular converter with phase-shifted SPWM and so on are analyzed and compared. The advantages and disadvantages of every control and their applied scope are pointed out. The feasibility of the unity power factor control is verified by simulation.
