Design and development of reconfigurable bidirectional isolated DC-DC converter for wide voltage range electric vehicle charging application

Abstract The escalating global adoption of electric vehicles (EVs) demands high-performance, flexible charging infrastructure capable of operating across wide battery voltage ranges. Conventional fixed-topology EV chargers exhibit significant efficiency degradation when operating outside their optimized voltage window. This paper presents the design and simulation of a reconfigurable bidirectional isolated DC-DC converter integrated with a three-phase Voltage Source Converter (VSC) front-end for EV charging applications spanning 200 V to 800 V. The DC-DC stage employs a dynamically reconfigurable LLC resonant topology capable of operating in Dual Active Bridge (DAB), Full-Bridge LLC (FB-LLC), and Half-Bridge LLC (HB-LLC) modes, selected adaptively based on runtime conditions. Zero Voltage Switching (ZVS) is maintained across the full voltage range through combined frequency and phase-shift modulation. The AC-DC stage uses Synchronous Reference Frame (SRF) control to achieve near-unity power factor and DC bus regulation at 800 V. MATLAB/Simulink simulation validates the proposed system, demonstrating efficiency exceeding 95%, input current THD below 3%, and robust performance under load transitions and mode-switching events. The reconfigurable architecture outperforms fixed-topology converters in flexibility and efficiency across dynamic EV charging conditions.
