A Non-Isolated Power Factor Correction Bridgeless High Gain Sepic Employing CPSO-PI Controller for Induction Motor Applications

Induction Motors (IMs) are widely employed in different industrial applications owing to their robustness and dependability. However, their operation often poses challenges in terms of Power Factor Correction (PFC) and voltage regulation, leading to inefficient energy utilization and harmonic distortions. Traditional PFC methods and voltage regulation techniques may not adequately address these issues. To overcome these issues, this paper develops a novel approach leveraging a non-isolated Bridgeless High Gain Single-Ended Primary Inductance Converter (SEPIC) with Chaotic Particle Swarm Optimization (CPSO) based Proportional Integral (PI) controller approach for IM applications. The proposed converter configuration aims to enhance power conversion efficiency and improve power factor with reduced Total Harmonic Distortion (THD). Furthermore, a control strategy termed a PI controller is employed to optimize the converter control performance, and the CPSO algorithm is introduced to optimally tune the PI parameters to achieve the desired settling time and rapid convergence speed performance, thereby enhancing the overall Efficiency and performance of IM. Furthermore, the developed topology is validated by utilizing MATLAB/Simulink, and the developed converter and control technique are compared with the other recent approaches to prove the greatness of the proposed system. The investigational outcomes prove that the proposed converter has reduced THD (1.98%), and the control technique performed better in terms of settling time and convergence speed. The developed work demonstrates its applicability and superiority for IM applications in terms of power quality enhancement and energy efficiency with a better PFC system.
