The issues related to power quality are becoming stronger; as the sensitive equipment plays a leading role in the power industry, it will pollute the system and increase the cost due to inbuilt compensation and deficiency of implemented regulations. Now, the cost and efficiency of the system are considered nearly at the identical level. Different active power filters were developed earlier to resolve the power quality issues. Among the series and shunt active power filter (SAPF), SAPF counterbalances the reactive power and brings down the load current harmonics. This paper presents both PI control and hysteresis current control based; three-phase SAPF in a three-wire three-phase system is implemented to even out the reactive power, harmonics and improving the total harmonic distortion for the nonlinear loads to improve power quality. This compensation process is a different approach only to sense the line currents and not the sensing of harmonics or load components of reactive power used in conventional methods. A MATLAB/Simulink environment is used to carry out the simulations. The obtained simulation results are the demonstration of improvement in power quality.
