With the growing global emphasis on decarbonization and sustainable energy alternatives, solar-driven hydrogen production has emerged as a promising solution for clean fuel generation. This study proposes a simulation-based design of a green hydrogen production system powered by photovoltaic energy. The architecture integrates SunPower SPR-215-WHT-U solar modules, a DC-DC boost converter, a full-bridge LLC resonant converter, and a Proton Exchange Membrane (PEM) electrolyzer. The boost converter enhances the PV voltage with reduced ripple, while the LLC resonant converter—operating at 65 kHz—enables soft-switching for improved efficiency...........

Keywords- Boost Converter, Full-Bridge LLC Resonant Converter, Green Hydrogen, MATLAB/Simulink, Maximum Power Point Tracking (MPPT), PEM Electrolyzer, Photovoltaic (PV).

The transition to electric mobility demands onboard chargers that are not only compact and efficient but also compliant with power quality standards. Nonlinearities introduced during AC–DC conversion often result in distorted input currents and reduced power factor, posing challenges to grid stability and charger performance. Addressing these concerns through simulation, a two-stage converter structure is modeled using MATLAB/Simulink, integrating a Boost Power Factor Correction (PFC) stage followed by an interleaved Single-Ended Primary Inductor Converter (SEPIC)............
