Abstract: In one general aspect, a converter circuit includes a magnetic core and a coil assembly. The coil assembly includes a primary winding assembly, a secondary winding assembly, and an auxiliary winding assembly. The primary winding assembly includes a conductive medium arranged in at least one primary winding layer. The secondary winding assembly includes a conductive medium arranged in at least one secondary winding layer. The auxiliary winding assembly includes a conductive medium arranged in at least one auxiliary winding layer. The at least one auxiliary winding layer includes an auxiliary winding layer disposed adjacent to a layer of the at least one primary winding layer and adjacent to a layer of the at least one secondary winding layer.
