Inventor(s) include R Vijayalakshmi; N Logadharshini; S Abinaya; and V Deepika.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "A solar-based intelligent boost converter system that effectively transforms variable solar energy into several regulated DC voltage levels, including 12 V, 36 V, and 48 V, is the subject of the current invention. The system is made to satisfy the growing need for flexible and sustainable DC power solutions that can run various loads with renewable energy. By cleverly modifying the output voltage in accordance with the needs of the connected device, it overcomes the drawbacks of traditional fixed-voltage converters. Energy efficiency and the adoption of green technologies are encouraged by the innovation, which combines renewable energy conversion with sophisticated electronic control and can be used in LED lighting, DC motors, e-bike batteries, and inverter systems. The main element for increasing and controlling the voltage is a MOSFET switching device, which is driven by a microcontroller-based Pulse Width Modulation (PWM) control mechanism. To maintain steady and accurate output regulation even in the face of varying load or solar input, the system makes use of real-time voltage and current feedback from the INA219 sensor. The microcontroller processes the sensor data and adjusts the PWM duty cycle to maintain the required output voltage. This closed-loop control increases efficiency, reduces losses, and improves overall performance. The system is adaptable for a range of applications because it can be used in both automatic and manual voltage selection modes. The proposed design also integrates Al-based load detection logic, which enables automatic recognition of the connected device and corresponding output voltage adjustment. To ensure safe operation, the system is equipped with over-voltage, over-current, and reverse-polarity protection circuits that protect both the converter and the connected loads from electrical damage. The system's, output and performance parameters such as voltage, current, and power are displayed on an OLED or LCD module for easy monitoring. Compact, cost-effective, and environmentally friendly, this solar-based intelligent boost converter provides a smart, reliable, and sustainable solution for multi-voltage DC power management in renewable energy systems."
