Abstract
Efficient and sufficiently accurate analytical models are valuable tools for the design of planar magnetic components. This paper describes a new analytical model of winding capacitances and dielectric losses for planar transformers. It is compared qualitatively with a more simple model valid for wire wound components and validated against measured capacitances of some prototypes. The new model can be used to optimize the design of planar magnetic components. Optimizing the thickness of the insulation layers between the copper layers of a planar winding is shown as an example.
