MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061869 A) filed by Mahendra Engineering College, Mallasamudram, Tamil Nadu, on May 15, for 'hybrid modulation framework for fault-tolerant electric boat propulsion systems driven by adaptive reinforcement learning.'
Inventor(s) include Mr. P. C. Sivakumar; Mr. M. Gokulakannan; Mr. S. Gokulnath; Mr. P. Jana; and Mr. K. Kathirvelan.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a hybrid modulation framework for fault-tolerant electric boat propulsion systems driven by adaptive reinforcement learning. The proposed system integrates multiple modulation techniques with intelligent reinforcement learning-based control for enhancing propulsion efficiency, reliability, and fault tolerance in marine applications. The framework includes a battery system, DC-DC converter, hybrid inverter, propulsion motor, sensor network, fault detection module, and adaptive modulation controller. The reinforcement learning algorithm continuously optimizes inverter switching patterns according to propulsion demand, battery condition, harmonic distortion, and fault status. The system dynamically switches between modulation techniques such as SPWM, SVPWM, and DPWM to maintain stable propulsion performance under varying operating conditions. The proposed invention significantly reduces switching losses, improves energy efficiency, enhances fault recovery capability, and ensures uninterrupted operation of electric boat propulsion systems."
