ALEXANDRIA, Va., May 19 -- United States Patent no. 12,633,829, issued on May 19, was assigned to The Regents of the University of California (Oakland, Calif.).

"Hybrid adaptive control for the DC-DC boost converter" was invented by Ryan S. Johnson (Santa Cruz, Calif.), Berk Altin (Santa Cruz, Calif.) and Ricardo G. Sanfelice (Santa Cruz, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A hybrid active controller for practically asymptotically stabilizing the DC-DC boost converter under parameter uncertainty. The controller uses an estimation algorithm that identifies the input voltage and output load of the converter in finite time. Using these estimates, the control algorithm "unites" global and local...
