Process model to estimate an inductance for a direct dc converter

This paper describes the analysis of inductances, carrying a triangular cur rent. Such inductances are used in the field of power electronics for buck- and boost-converters. Since the layout of such a coil requires either labo rious numerical simulations or comprehensive practical experiences, a reduc ed process model is derived in this case which allows estimations with suff icient exactness and a sufficient variety of parameters. Based on the elect romagnetic field distribution in the inductance the given geometry is reduc ed gradually in a way that the field distribution changes only insignifican tly, however, calculation is becoming easier. The resulting reduced process model allows calculation of the electric field parameters by means of an a nalytical relation, which makes it easier to examine the dissipation power of different variants. Finally, the process model is used for optimization.
