ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,451,286, issued on Oct. 21, was assigned to Delta Electronics Inc. (Taipei, Taiwan).

"Planar winding structure for power transformer" was invented by Ruxi Wang (Cary, N.C.), Zhiyu Shen (Cary, N.C.), Chi Zhang (Apex, N.C.) and Peter Mantovanelli Barbosa (Cary, N.C.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The present disclosure provides a printed circuit board (PCB) based planar winding structure for a main power transformer and/or an auxiliary power need. The PCB-based planar winding structure can confine electric field through magnetic core potential control and thus create partial discharge (PD) free design for medium voltage (MV) applications. ...
