摘要：

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