Abstract

Grid-integrated photovoltaic (PV)-powered electric vehicle (EV) charging stations offer a sustainable solution for reducing grid dependency and fossil fuel consumption in workplace environments. This study proposes a PV-powered EV charging system with an AC bus configuration and grid support to ensure stable and efficient operation. A comparative analysis of four DC-DC converter topologies—Dual Active Bridge (DAB), LLC Resonant, Interleaved Buck-Boost, and Interleaved Buck—is conducted for offboard charging applications. Performance evaluation is carried out using MATLAB/Simulink, considering voltage and current ripple, power density, stress levels, bidirectional capability, and control complexity. Component-level reliability is assessed using MIL-HDBK-217 standards to estimate failure rates under operational conditions. Additionally, a cost-saving analysis based on 2024 NASA POWER solar irradiance data demonstrates the economic viability of PV-based EV charging. The findings serve as a design reference for implementing efficient, reliable, and cost-effective EV charging infrastructure and provide practical guidance for selecting suitable converter topologies in industrial applications.
