This paper present the uses of new technologically advancement controlled technique “Shunt Active Power Filter (SAPF) in three phase four wire system” for improving the power quality of network. The industry has many of non-linear loads that are the sources of harmonics in the system that creates the power quality problems. Three phase Four wire Shunt Active Power Filter is used to solve this power quality issues. In the Shunt Active Power Filter a new control algorithm is proposed for 3-phase 4-leg system based on Instantaneous real-power theory, also known as p-q theory suppress harmonic currents, compensate reactive power and neutral line current and balance load currents under unbalanced non-linear load condition. The Active Power Filter is composed from 4-leg voltage source inverter with a common DC-link capacitor and hysteresis-band current controller. The simulation results on MATLAB/Simulink tool are present.
