1D/2D transformer electric model for simulation in power converters

This paper describes two complete electric models that characterize transformer windings. The models have the geometric information of the magnetic component and give accurate results for high frequency simulations. Both models are derived from Maxwell equations and the expressions to calculate the electric parameters directly from the geometry are shown. The models are suitable to be included in any simulation programs having very short generation time. This fact avoids the use of complex finite element analysis (FEA) tools.<>
