Adaptive perturb and observe (P&O)-fuzzy control maximum power point tracking (MPPT) for photovoltaic (PV) dc-dc converter is proposed in this research. The fuzzy logic methodology and P&O advantages are combined in the proposed method. P&O is noted for its simplicity and widespread use, while fuzzy is known for its speed and simplicity. MPPT's performance should be improved by combining these techniques, especially given the current level of noise. MATLAB-Simulink was used to simulate the algorithms using a Kyocera KD210GH-2PU PV module and a PV boost dc-dc converter.
