This paper shows the method of improving the power quality using shunt active power filter. The proposed topic
comprises of PI controller, filter hysteresis current control loop, dc link capacitor. The switching signal generation for filter
is from hysteresis current controller techniques. With the all these element shunt active power filter reduce the total
harmonic distortion. This paper represents the simulation and analysis of the using three phase three wire system active
filter to compensate harmonics .The proposed shunt active filter model uses balanced non-linear load. This paper
successfully lowers the THD within IEEE norms and satisfactorily works to compensate current harmonics. The model is
made in MATLAB / SIMULINK and successfully reduces the harmonic in the source current
