A redesigned quadratic boost DC-DC converter design with high voltage gain, low component count, less switching stress, and improved overall efficiency is shown in this work. It is specifically made for EV charging. Additionally, a two-stage constant current (CC) charging method is created for an EV charging system that runs on solar power. A thorough quadratic layout with input voltage boosting, steady-state operations, and inductor current conduction states is shown in this study. It also incorporates mathematical analysis that considers non-ideal situations, parameter design criteria, and a comparison of the suggested converter's performance with that of current ones. Initial validation of the converter's performance is done using MATLAB/Simulink simulations at a power level of 3 kW. The suggested topology is then included into an architecture for EV battery charging that is powered by PV. To efficiently extract solar electricity, an MPPT algorithm based on feedforward neural networks is used. A two-stage CC charging technique that dynamically modifies the charging current based on the battery's state of charge (SOC) is used to improve battery health.
