Abstract

An auxiliary winding circuit board includes one or more auxiliary conductive windings. The auxiliary winding circuit board is positioned at an axial end of a bobbin, and a core leg extends through an opening in the auxiliary winding circuit board. A main conductive winding is positioned on the bobbin. The auxiliary winding disposed on the auxiliary printed circuit board has enhanced voltage-isolation from the main winding positioned on the bobbin, allowing both a high-voltage main winding and a low-voltage auxiliary winding to be located on one magnetic component. The magnetic component is configured for mounting on a printed circuit board for an electronic device such as a power supply. A modular magnetic component apparatus includes a bobbin with main winding assembly and multiple auxiliary winding circuit boards that may be interchangeably mounted between the bobbin and core for desired applications.
