US Patent Issued to RENESAS ELECTRONICS AMERICA on May 26 for "Adaptive zero voltage switching for near field communication" (Swiss Inventor)

ALEXANDRIA, Va., May 26 -- United States Patent no. 12,640,596, issued on May 26, was assigned to RENESAS ELECTRONICS AMERICA INC. (Milpitas, Calif.).

"Adaptive zero voltage switching for near field communication" was invented by Marco Sautto (Zurich).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for operating a wireless power transfer device are described. A circuit can generate a first signal that indicates a voltage at a node between a first high-side (HS) transistor and a first low-side (LS) transistor in a switching converter falling below ground. The circuit can delay a gate-source voltage of a second LS transistor in the switching converter to generate a second signal. The circuit ...
