Harmonic Elimination Using Hybrid Filter

Abstract: This paper presents a Harmonic elimination using series active shunt passive filter based hybrid filter. Filter operation is based on PLL logic which comprised with PI controller and mathematical operation on voltage signals. The proposed approach is comprised of PLL based series active filter with shunt passive filter. Here passive filter design is done based particular frequency calculations. The series active filter switching gives better steady state operating conditions. The hybrid filter system is used for many simulation of different loads which reveals that it effectively compensate reactive power as well voltage and current harmonics.
