Abstract :
A novel voltage sag compensator with double-layer capacitor is presented. The discharge characteristics of the double-layer capacitors and the maximum load capacity of the system are investigated on the basis of the equivalent circuit including capacitors and a voltage booster. Furthermore, main circuit design of the system is explained. Finally, simulation results show the validity of the design and the ability of the compensator.
