MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202611061823 A) filed by Delhi Technological University on May 15, 2026, for System And Method For Preventing Hotspot Formation And Improving Power Extraction Efficiency In Photovoltaic Arrays.
Inventors include Yadav, Vinod Kumar; Singh, Santosh Kumar; and Ghosh, Swatilekha.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present disclosure relates to system (100) for preventing hotspot formation in photovoltaic array configurations includes a plurality of photovoltaic modules (102) configured to generate electrical power and interconnected in at least one of a series, series- parallel, or total cross-tied configuration; an active bypass switch (104) electrically connected in parallel across at least one group of photovoltaic cells within each photovoltaic module (102) to provide an alternate current path for preventing reverse biasing and thermal stress; a voltage sensing unit (110) operatively connected across each photovoltaic module (102) and the array to continuously measure instantaneous module voltages and array voltage for real-time monitoring; a maximum power point tracking controller (108) electrically coupled to the array to determine a maximum power point and compute an average module voltage; a comparator unit (112) configured to detect mismatch conditions; a processor (116) configured to generate a control signal; a gate driver circuit (106); and an optocoupler (114) enabling isolated activation of the bypass switch.
