The rapid penetration of electric vehicles (EVs) and renewable energy sources poses significant challenges to grid stability and energy management. Solar-powered bidirectional EV charging systems with grid support capability have emerged as a promising solution to enhance system flexibility and reliability. This paper presents the design and control of a solar-powered bidirectional EV charging circuit operating in Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) modes using a Fuzzy Logic Controller (FLC). The proposed system intelligently manages power flow between the photovoltaic (PV) source, EV battery, and utility grid under varying solar irradiance, load demand, and grid conditions. The fuzzy controller eliminates the need for an accurate mathematical model and ensures smooth mode transition, reduced current stress, and improved power quality. MATLAB/Simulinkbased simulation results demonstrate effective charging/discharging control, stable DC-link voltage regulation, and enhanced grid support during peak demand and voltage fluctuations. The proposed control strategy offers a robust and adaptive solution for smart grid–integrated EV charging infrastructures
