三相有源电力滤波器直流电容电压波动的动态控制与分析

This paper proposes a new control method of three-phase active power filters for reducing the dc capacitor voltage fluctuations in transient load change. The proposed control method introduces a new k-step compensator, which maintains the mean active power flowing into the dc capacitor at zero every 1/(k-1) ac line period. Therefore, the compensator can suppress the transient voltage fluctuations ...
