MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641047982 A) filed by Mohan Babu University, Tirupati, Andhra Pradesh, on April 15, for 'a new fault tolerant multilevel inverter for electric vehicle applications.'
Inventor(s) include Dr. Busireddy Hemanth Kumar; Mr. C. Chaithanya; Mr. K Munisai; Mr. P Joel; Mr. N Dheemanth Reddy; and Mr. T. Sai Krishna Reddy.
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 discloses a fault-tolerant multilevel inverter (FTMLI) topology designed for electric vehicle applications and other critical power systems. The proposed five-level inverter operates using a reduced number of unidirectional and bidirectional switches, offering compactness and improved reliability. It incorporates redundant conduction paths and dual switching strategies to detect and mitigate open-circuit faults in power switches. Upon detecting a fault, the inverter autonomously reconfigures its operation to maintain essential voltage levels without requiring additional hardware such as auxiliary legs or external modules. The inverter ensures continuous, efficient operation under single or selected multiple switch faults, significantly enhancing system robustness and performance."
