  • Abstract:
  • The rapid growth of electric vehicles (EVs) has increased the demand for efficient and high-speed charging infrastructure. This paper presents the design and simulation of a DC fast charging system for EV applications using MATLAB/Simulink. The proposed system converts three-phase AC grid power into a regulated DC output suitable for fast battery charging. The architecture includes an AC grid source, filtering unit, unity power factor (UPF) front-end converter, DC bus, isolated DC-DC converter, and EV battery pack. The front-end converter ensures stable DC voltage output of approximately 800 V while maintaining power quality and reducing harmonic distortion. The DC-DC converter, equipped with a high-frequency transformer and rectifier, provides electrical isolation and controlled charging current to the battery. The system also incorporates measurement and control units for monitoring voltage, current, and state of charge (SOC). Simulation results demonstrate stable DC bus voltage, efficient energy conversion, and smooth battery charging characteristics. The proposed model achieves improved efficiency, reduced losses, and enhanced system reliability. This work contributes to the development of advanced EV charging infrastructure and supports the transition toward sustainable transportation systems.
