MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202431099967 A) filed by Indian Institute Of Engineering Science And Technology, Howrah, West Bengal, on Dec. 17, 2024, for 'a test-bench for in-process performance determination of high-frequency inductors having different core and winding geometries.'
Inventor(s) include Dr. Mainak Sengupta; and Mr. Gourab Banerjee.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a test-bench system for in-process performance evaluation of high-frequency inductors. The system comprises a voltage source-based DC bus derived from a rectifier, a plurality of interleaved half-bridge circuits with hard-switching and freewheeling devices, and non-coupled branch inductors connected to a test inductor. The arrangement enables real-time estimation of inductor parameters, including inductance, AC and DC resistance, parasitic capacitance, flux linkage, and core losses, without interrupting converter operation. The estimation is based on ?L-iL characteristics, RAC/RDC variation with frequency, impedance at multiple frequencies, and B-H characteristics, incorporating effects of switching frequency, temperature, and magnetic saturation. The system accommodates inductors of various core geometries, materials, and winding configurations, offering an efficient, scalable, and accurate platform for inductor characterization in high-frequency power electronic applications."
