US Patent Issued to STMicroelectronics on Sept. 15 for "Detecting transformer saturation in switched-mode power supplies" (Italian Inventor)

ALEXANDRIA, Va., Sept. 15 -- United States Patent no. 12,738,852, issued on Sept. 15, was assigned to STMicroelectronics S.r.l. (Agrate Brianza, Italy).

"Detecting transformer saturation in switched-mode power supplies" was invented by Fabio Cacciotto (Catania, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "According to an embodiment, a flyback converter includes a transformer, a power switch coupled to the primary winding of the transformer, and a controller. The controller comprises a voltage-dependent current source, a reference capacitor, comparators, and logic circuitry. The controller estimates the primary inductance of the transformer based on the voltage across the reference capacitor, detects ...
