Electronic circuits suitable for converting, controlling and conditioning electrical energy in solar applications are required to ensure efficient use of the solar system. This paper proposes a stand-alone system consisting of a Maximum Power Point Tracking (MPPT) algorithm and a fuzzy logic based voltage controller for a photovoltaic application. The fuzzy logic-based intelligent algorithm MPPT controls the DC-DC boost converter to find the best Maximum Power Point (MPP) with speed and

The fuzzy logic-based voltage controller is designed using the T-Standards and the standardization process to improve transient control performance. Voltage Regulation Control with Adaptive Fuzzy Logic for a Stand-alone Photovoltaic System is designed and simulated in the MatLab/Simulink environment. The results show that the fuzzy controller effectively resolves system voltage instability by keeping the DC-DC buck converter voltage constant despite variable weather and load conditions.
