To break the power limit of APF(Active Power Filter) caused by the smaller capability of switching devices,the three-phase three-wire three-level APF based on vector mode one-cycle control is presented.
为克服由于开关器件容量小而导致有源电力滤波器(APF)功率受到限制的问题,提出了一种基于矢量模式单周控制的三相三线制三电平APF,APF主电路采用二极管箝位型三电平拓扑结构,控制策略采用0°~360°区间矢量模式单周控制,以减小APF开关应力和损耗,实现用低耐压开关器件提高APF功率等级。

A three-phase three-wire active power filter(APF),controlled by one cycle controller is devised.
设计了一种单周控制的三相三线制有源电力滤波器,该滤波器工作时无需检测三相负载电流和三相输入电压,无需进行繁琐的参考电流、无功电流和谐波电流计算;只需检测两相电源电流和直流侧电容电压,通过简单计算就可直接求出每个开关周期内各开关的占空比。
