The growing trend of electric cars (EVs) can be attributed to their low greenhouse gas emission and decreased reliance on fossil fuels. But the procedure of charging the batteries is where the main obstruction in the EV transportation system is found. Key elements of the EV charging framework include resolving power factor correction (PFC) concerns and optimising the DC converter stages. Different power electronic converter designs, including the Single-Ended Primary-Inductor Converter (SEPIC), Cuk, Zeta, Luo, and Buck-Boost converter, are used in different charging systems. For battery charging applications, the SEPIC converter design is the most popular among them. The three biggest obstacles to be addressed are reducing voltage stress, increasing conduction efficiency, and decreasing converter size. This research project suggests a redesigned two-switch isolated ac to DC SEPIC converter to improve Power Quality (PQ) in automobile charging stations. The recommended setup seeks to reduce power losses, increase converter efficiency, and lessen voltage stress. MATLAB Simulink is used to evaluate the converter’s performance. Several test scenarios are run with input supply voltages varying between 70 and 230 V AC.
