: Power Generation Systems use green energy sources such as Solar Energy Systems (SES), Wind Energy Systems (WES), and Fossil Fuels to address conversion efficiency challenges. To improve efficiency, DC-DC converters like SEPIC, Buck-Boost, and CUK are used, with SEPIC being the most effective in Hybrid Systems, addressing issues in Buck-Boost converters. An MPPT controller maximizes power extraction and Fuzzy Logic enhances MPPT performance by adapting to rapid input changes. The Hybrid System integrates Solar PV and Wind Energy Conversion Systems using Fuzzy Logic-based SEPIC converters to regulate the output and ensure a stable DC supply. The Simulink model developed demonstrates a Fuzzy Logic-based MPPT controller applied to a SEPIC converter connected to a PV and Wind Energy Conversion System. In this model, real-time voltage and current measurements are used to calculate power, and the Fuzzy Controller adjusts the duty cycle to keep the system operating at the Maximum Power Point. The model was tested under different irradiance conditions to verify stable tracking. This paper focuses on designing and analyzing a Fuzzy Logic-based solar-wind hybrid system with Battery backup to support AC and DC Loads, ensuring an Uninterrupted Power Supply. A Wind Energy Source with a PMSG and rectifier can be added to the same DC bus using the same Fuzzy Logic MPPT method. Overall, the Simulink model demonstrated improved power tracking and supported the integration of hybrid PV-Wind systems.
