ELECTRICAL VEHICLE CHARGING WITH INTRELEAVED CONVERTER

Abstract: The rapid growth of electric vehicles (EVs) has increased the demand for efficient and reliable charging systems. Conventional chargers often suffer from high current ripple, poor power quality, and thermal stress. To overcome these challenges, this work proposes an EV charging system using an Interleaved DC–DC Converter. Multiple converter phases operate with phase-shifted control signals to share load current, reducing current ripple, switching losses, and thermal stress. The system includes a front-end AC–DC rectifier with power factor correction followed by the interleaved converter for regulated battery charging. Simulation results show improved efficiency, lower total harmonic distortion (THD), and better dynamic performance compared to conventional converters.
