Abstract: - The growing adoption of electric vehicles (EVs) worldwide has brought new challenges in the realm of power management and grid stability. One of the key components in this ecosystem is the EV charger, a device that facilitates energy transfer between the power grid and the EV battery. The increasing adoption of electric vehicles (EVs) necessitates the development of advanced charging systems that are both efficient and compatible withmodern electrical grids. This paper presents the design and implementation of a high efficiency EV charger based on a Single-Ended Primary-Inductor Converter (SEPIC) topology integrated with Power Factor Correction (PFC). The SEPIC converter is chosen for its ability to operate effectively across a wide range of input and output voltages, making it ideal for the dynamic requirements of EV charging. The SEPIC converter is selected for its ability to efficiently manage varying input voltages and provide a stable output, making it ideal for EV charging applications. The SEPIC topology offers the flexibility to both step up and step down the input voltage, ensuring consistent charging regardless of fluctuations in the grid or renewable energy sources. This capability is crucial for maintaining the health and longevity of the EV battery. Through this project we are going to simulate the entire working of the proposed EV charger using MATLAB SIMULINK and also to view the operation of this EV charger. Key Words: EV Charger, SEPIC Converter, SoC, PFC.
