Abstract:

This paper presents the design and simulation of a Single-Ended Primary Inductor Converter (SEPIC) converter for EV battery charging applications. The SEPIC converter is a type of DC-DC converter designed to provide a steady output voltage while accommodating a wide range of input voltages. Known for its high efficiency and reliability, the SEPIC converter can regulate the output voltage to be either higher or lower than the input voltage. DC-DC converters are particularly appealing to researchers due to their low output voltage ripple and high efficiency, making them ideal for applications requiring low noise and high power density. Continuous advancements in DC-DC converter performance and reliability are essential to meet modern technology's growing demands. The SEPIC converter, sharing similarities with the buck-boost converter by incorporating both buck and boost functions, offers advantages such as having input and output voltages with the same polarity, high efficiency, and capacitor isolation between the output and the input sides. The simulation of the SEPIC converter in both open-loop and closed-loop configurations is carried out using MATLAB software and presented in this paper.
