MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641048376 A) filed by Dr. T. Papinaidu; G. Sekhar; D. Vidya Sagar; A. Chiranjeevi; and G. Surendra Naidu, Vizianagaram, Andhra Pradesh, on April 16, for 'grid-connected pv system with hybrid fuzzy-neural mppt under partial shading.'
Inventor(s) include Dr. T. Papinaidu; G. Sekhar; D. Vidya Sagar; A. Chiranjeevi; and G. Surendra Naidu.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The system (100) includes a a photovoltaic array (102), a voltage and current sensing unit (104), a hybrid fuzzy-neural MPPT controller (106), a DC-DC converter (108), a grid synchronization unit (110), a DC-AC inverter (112), and a grid interface unit (114). The photovoltaic array (102) generates electrical energy based on solar irradiance and environmental conditions. The voltage and current sensing unit (104) continuously measures the output parameters of the photovoltaic array (102). The hybrid fuzzy-neural MPPT controller (106) determines the optimal operating point under partial shading conditions. The DC-DC converter (108) regulates voltage levels. The grid synchronization unit (110) ensures compatibility with grid parameters. The DC-AC inverter (112) converts DC to AC power. The grid interface unit (114) supplies power to the grid. The invention enhances maximum power extraction efficiency under partial shading. The invention facilitates stable and reliable grid-connected PV operation."
