Design and Analysis of High Gain Boost Converter Using Improved Seeking Optimization Algorithm for Electric Vehicles

Abstract

This paper seeks to demonstrate a way to optimize a high-gain DC-DC boost converter designed for use in electric vehicle (EV) applications by utilizing the Improved Seeking Optimization Algorithm (ISOA), which is a new method of optimization. The proposed boost converter is designed to have a non-isolated, non-coupled inductor configuration so that it can be built into a high-gain boost converter operating with a low duty cycle, allowing for reduced voltage stress on the power switches. The recommended boost converter design uses only two power switches and one PWM control signal thereby making the system compact, lightweight and inexpensive. The ISOA optimization method is also applied to the design parameters of the boost converter: duty cycle, switching frequency and passive component selection for maximum performance improvement. The optimized boost converter incurs minimal power losses and the output voltage remains constant given that the load varies. The effectiveness of the suggested strategy is proved by performance of the optimized boost converter that can be verified with the help of MATLAB/Simulink simulations. Therefore, the suggested boost converter is applicable to the effective functioning in the present-day EV electric systems.
