Abstract

Is there any influence of supply voltage fluctuation on the shunt active power filter? Few papers have discussed this problem. In this paper, based on the instantaneous power balance of shunt active power filter ac-side and dc-side, a small signal model of dc-link voltage control is derived. According to this small signal model, the influence of supply voltage fluctuation on dc-link voltage of shunt active power filter is analyzed in detail. And the conclusion is that the supply voltage fluctuation has influence on dc-link voltage of shunt active power filter. Then a feedforward control method of the supply voltage and the compensation current is proposed to eliminate the influence in this paper. Finally the experimental results also are given to demonstrate the conclusions
