ABSTRACT
In Chapter 2, shunt active filter (SHAF) control strategies were discussed. It is concluded that under unbalanced and nonsinusoidal conditions, the PI controller is unable to mitigate the harmonics completely and THD is close to 5%. But, according to IEEE 519-1992, THD must be less than 5%. So to mitigate the harmonics perfectly, one has to choose the perfect controller.
