Objective: This study presents the unified power quality conditioner (UPQC) which is based on eight switch converter for dropping the total harmonic distortion. Alleviation of power quality is accomplished by power fed to the DC link of the converter and regulates the power using intelligent controller. Methods: The function of UPQC is determined by how fast and precisely compensation signals are estimated. The UPQC has presented for reducing the coupling problem by the presence of switching leg. In the distributed system needs to explain the approaches for standard supply voltage droop and voltage swell. Findings: The harmonics is reduced and produces the dynamic response in eight switch converter using genetic algorithm (GA). Application/ improvements: In the distribution system eight switch converter based UPQC has generated the steady state and dynamic process of control in nonlinear load and/or utility voltage conditions is implemented in MATLAB Simulink.
