| Abstract |
Thin planar transformers must be modelled at high frequency, but the
parameters of the equivalent circuit are difficult to compute, because we have to take into account their 3D geometry. In this paper, we present a method of computation of the inductive, capacitive and resistive parameters of a type A planar transformer, based on the
3D finite element method with magnetodynamic and electrostatic formulations. The followed approach has been validated by comparison of simulation results with measurements. The model employed has satisfying accuracy up till 15MHz. |
