Novel PCB Integrated Magnetic Component Design for Reduced AC Power Losses

Inductor design for medium-to-high frequency operation requires special attention to winding ac losses (skin and proximity effect). Integrating novel winding design geometries into the PCB has the potential to provide significant design flexibility to mitigate skin and proximity effect induced winding power losses. This paper will describe three methods to mitigate winding conductor ac losses that are applicable to both core-less and cored magnetic components.
