A Unique single phase Active power shunt filter for vehicle energy storage systems employing Parabolic Based PWM Technique

Abstract

This paper describes a new power electronic filter for use in electric vehicles. The filter is designed to mitigate the high-frequency switching noise generated by the power electronics used in electric vehicle energy storage systems. The proposed filter uses a unique parabolic-based pulse width modulation technique to control the switching of the filter, which reduces the high-frequency noise while maintaining the efficiency of the system. The paper provides simulation results to show the effectiveness of the proposed filter in reducing the high-frequency noise and improving the power quality of the system. The research paper highlights the potential of the proposed filter to improve the performance of electric vehicles and other energy storage systems. The results show that, Matlab-Simulink simulation was used to investigate the effectiveness of a suggested SAPF (Shunt Active Power Filter) design in reducing harmonic distortion in a system. The goal of the study was achieved with  a low harmonic percentage, and the simulation results showed that the suggested SAPF design has achieved a harmonic percentage as low as 2.18%.
