US Patent Issued to Tula eTechnology on May 13 for "Boosted rotor supply circuit and method for improving pulsed electric machine efficiency" (California Inventors)

ALEXANDRIA, Va., June 12 -- United States Patent no. 12,301,151, issued on May 13, was assigned to Tula eTechnology Inc. (San Jose, Calif.).

"Boosted rotor supply circuit and method for improving pulsed electric machine efficiency" was invented by John W. Parsels (San Jose, Calif.) and Babak Mazda (Los Altos, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A boost circuit and method is described for supplying a boost voltage to a rotor of the electric machine, just as the electric machine is pulsed on, the boost voltage aids the rotor in quickly overcoming its start-up inductance, rapidly turn on the rotor. As a result, much faster transition times are realized each time the electric machine transition...
