MUMBAI, India, April 20 -- Intellectual Property India has published a patent application (202514091561 A) filed by Power Integrations, Inc., San Jose, U.S.A., on Sept. 24, 2025, for 'a high side on-time control circuit and method for an asymmetrical half-bridge power converter.'
Inventor(s) include Sheng Liu; Arthur B. Odell; Roland Sylvere Saint-Pierre, Jr.; Sundaresan Sundararaj; Qing Wang; and Yueming Wang.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The circuits and methods of the present disclosure control the active off-time (high side switch on-time) to ensure the magnetization energy release and resonant capacitor energy release in an asymmetrical half-bridge (AHB) converter finish at the same time and all the stored energy is delivered to the output in each switching cycle. Multiple, parallel, techniques to control the high side switch on-time are illustrated. One is to track the volt-seconds applied during the storage cycle and allow the active release off-time to be limited to the same volt-seconds. A second option is to provide a high side switch on-time that is proportional to the on-time of the low side switch in that switching cycle. A third option is to provide a maximum high side switch on-time that can be programmed to ensure the high side on-time is equal to or smaller than half of the resonant period."
