MUMBAI, India, June 16 -- Intellectual Property India has published a patent application (202611055288 A) filed by Indian Institute Of Technology, New Delhi, on April 30, for 'dc-dc isolated power transfer system and method using dual three-phase voltage source inverter.'

Inventor(s) include Avanish Tripathi; Rabindra Mohanty; and Dev Kumar.

The application for the patent was published on June 5, under issue no. 23/2026.

According to the abstract released by the Intellectual Property India: "The present invention discloses a DC-DC isolated power transfer system (100) and a method (400) of transferring power between DC sources. The system (100) employs dual three-phase voltage source inverters (VSIs) interconnected through a transformer stage (116). A first VSI (106) operates in a grid-forming mode to generate a controlled three-phase AC voltage from a first DC source, while a second VSI (124) operates in a grid-following mode synchronized to the generated AC voltage to supply a second DC source. The transformer stage (116) includes plurality of single-phase high-frequency transformers establishes a three-phase AC link and provides galvanic isolation, with inherent leakage impedance enabling high-frequency filtering. The system (100) also has a three-phase filter network (110) to attenuate switching harmonics. The system (100) operates within linear modulation regions of the VSIs and transformers, reducing DC-link capacitor requirements and thermal stress."
