ALEXANDRIA, Va., March 26 -- United States Patent no. 12,261,526, issued on March 25, was assigned to Intel Corp. (Santa Clara, Calif.).
"Computational current sensor" was invented by Harish K. Krishnamurthy (Beaverton, Ore.), Xun Sun (Seattle) and Krishnan Ravichandran (Saratoga, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A computational current sensor, that enhances traditional Kalman filter based current observer techniques, with transient tracking enhancements and an online parasitic parameter identification that enhances overall accuracy during steady state and transient events while guaranteeing convergence. During transient operation (e.g., a voltage droop), a main filter is bypassed with e...
