三电平四桥臂有源滤波器主电路参数设计

The Design of Main Circuit Parameters of Three-Level Four Bridge Active Filter

大功率开关器件及线路元件价格昂贵,选取合适的参数可使滤波器既能满足控制性能的要求,又可使滤波器经济价格合理。因此,针对三电平四桥臂有源滤波器主电路,根据滤波器的容量设计选取功率开关器件、直流侧储能电容和进线电抗器参数,给出了一种参数选取方法。

Due to the high cost of high-power switch devices and circuit elements,proper parameters are selected to make the filter meet the control performance requirements and make the design price of the filter economical and reasonable.Aiming at the three-level four-leg active power filter main circuit,this paper designs and selects the parameters of power switching device,DCside energy storage capacitor and inlet inductor according to the capacity of the filter.
