ALEXANDRIA, Va., June 9 -- United States Patent no. 12,651,972, issued on June 9, was assigned to STMicroelectronics International N.V. (Geneva).
"Synchronous rectification adaptive turn-on/turn-off method" was invented by Stefano Manzoni (Milan) and Daniele Cazzaniga (Lissone, Italy).
According to the abstract* released by the U.S. Patent & Trademark Office: "A DC-DC LLC resonant-converter utilizes a synchronous-rectifier stage with first and second branches. In a calibration-cycle, a first elapsed-time from commutation of a drain-to-source voltage of the first branch's transistor, through inversion of the current in the first branch, to a next zero-crossing of that current is measured, and a second elapsed-time is measured the same way ...
