Abstract

A conventional isolated full-bridge (FB) DC–DC converter for electric vehicle (EV) battery charger is implemented and experimentally validated using a real-time digital control platform based on the dSPACE DS1104 controller presented in this paper. The proposed charger is designed to deliver a regulated output of 56 V at 15 A for charging a 48 V lithium-ion battery pack. This work focuses on practical power-stage design with appropriate semiconductor device selection, high-frequency transformer design, output filter design considering switching stress mitigation. To address electromagnetic interference (EMI) in full-bridge converters due to high dv/dt and di/dt switching transitions, a passive mitigation approach with an input capacitor and RC snubber network is presented. This method reduces voltage overshoot and switching stress without increasing control or circuit complexity. A PI-based voltage control strategy is implemented on the dSPACE DS1104 platform for real-time PWM generation, closed-loop regulation and direct observation of converter dynamics during operation. The proposed system is validated through simulation and experimental testing results demonstrating stable output regulation, reduced switching stress and improved EMI behaviour. The results highlight the suitability of dSPACE-based real-time control for rapid prototyping and experimental investigation of power stages for isolated EV charger. The study provides practical implementation insights and a systematic design reference for researchers and engineers working on real-time EV battery charger development.

Keywords: Full-Bridge DC–DC Converter, dSPACEDS1104, electromagnetic interference, electric vehicle (EV) charger, real-time digital control.
