Inventor(s) include Sarvesh Atul Birla; Rajendra Sawant; Reena Sonkusare; Varun Adhiya; and Mangesh Dalvi.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "This invention introduces an advanced flux vector modulation technique specifically designed for single-phase voltage source inverters equipped with LC output filters. Unlike conventional approaches, this method achieves stable inverter operation without requiring additional passive components or active damping controllers, thereby simplifying system architecture and enhancing efficiency. The modulation strategy is grounded in a robust theoretical framework, detailing the mathematical principles and control dynamics underlying flux vector modulation. A synchronously rotating reference frame proportional-integral (PI) controller is utilized for precise output voltage regulation, effectively mitigating resonance associated with LC filters. The implementation process of the modulation technique is detailed, including integration steps for real-world applications, making it adaptable for diverse operational conditions. Experimental validation conducted in a laboratory setting confirms the method's efficacy in damping LC filter resonance, maintaining stable inverter operation across varying load conditions, and achieving low total harmonic distortion. This innovation is particularly relevant for improving the dynamic performance, reliability, and efficiency of small-scale distributed generation systems. By enhancing stability and operational efficiency, this invention supports seamless integration into electrical grids, further advancing the reliability and adoption of renewable energy sources in modern power systems."
