ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,456,912, issued on Oct. 28, was assigned to Da Feng Weng (Sunnyvale, Calif.).
"Forward DC-DC ZVS converter and control scheme" was invented by Da Feng Weng (Sunnyvale, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "The proposed solution allows a forward DC-DC converter's isolated transformer to resonant reset and the forward DC-DC converter to operate in ZVS condition regardless of whether the output inductor current is in DCM or CCM. To compare with a regular forward DC-DC converter, the output isolated transformer has an extra reset winding Nt in addition to the regular primary and secondary windings Np and Ns. Based on the rule of the magnetic...
