Synchronous PI decoupling 방법을 사용한 DVR 인버터 최적 제어 기법 = Synchronous PI decoupling control method for DVR Inverter System

다국어 초록 (Multilingual Abstract)

A new control strategy for driving the dynamic voltage restorer (DVR) is proposed. It is based on the synchronous PI decoupling control strategy which features fast response and low steady state error. Therefore, the proposed control strategy takes the faster action against voltage sag and guarantees more enough compensation for the sagged supply voltages. In addition, since the currents flowing through the ripple filter inductor are used as the supplementary control variables, it is possible to protect the switching power device against the surge current in the proposed control strategy. The simulation results and experimental results are shown to validate the effectiveness of the proposed control strategy.
