US Patent Issued to Qorvo US on Nov. 25 for "Calibrated zero inductor current detection in direct current (DC) to DC converters" (Dutch Inventors)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,108, issued on Nov. 25, was assigned to Qorvo US Inc. (Greensboro, N.C.).

"Calibrated zero inductor current detection in direct current (DC) to DC converters" was invented by Vikram Chaturvedi (Utrecht, Netherlands) and Salvatore Pirruccio (Woudenberg, Netherlands).

According to the abstract* released by the U.S. Patent & Trademark Office: "Power efficiency can be optimized in a direct current (DC)-DC converter in discontinuous conduction mode (DCM) if a transition from a state of decreasing inductor current to a state of zero inductor current occurs as close as possible to the decreasing inductor current reaching zero. The timing of a zero current indication is affected by a vol...
