MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050640 A) filed by Mohan Babu University, Tirupati, Andhra Pradesh, on April 21, for 'single-switch step-up dc-dc converter system for renewable energy power conversion.'
Inventor(s) include Mr. Meesala Anil Kumar; Mr. Ravada Durga Prasad; Mr. Shaik Novmaan; Mr. Mohd Abdul Latheef; Mr. K. Adi Kesava Reddy; and Dr. Nmg Kumar.
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 present invention relates to a single-switch step-up DC-DC converter designed for renewable energy applications. Renewable energy sources such as solar photovoltaic panels and fuel cells typically generate low and variable DC voltages that require voltage step-up conversion before being used in practical applications. The proposed converter integrates boost converter and Luo converter topologies in a cascaded configuration controlled by a single switching device. This design achieves high voltage gain while maintaining a simple circuit structure and efficient power conversion. The converter operates by storing energy in an inductor during the switching ON state and transferring the stored energy to the output during the OFF state. The cascaded converter stages increase the voltage gain while maintaining stable output voltage. A pulse-width modulation control mechanism regulates the switching operation to maintain constant output voltage under varying load and input conditions. Simulation results demonstrate that the converter achieves high efficiency and stable performance while reducing circuit complexity. The proposed system provides an efficient and compact solution for voltage step-up conversion in renewable energy systems, electric vehicle charging systems, and DC microgrid applications."
