Equivalent Circuit of AC Magnetic Fields

Abstract
An effective equivalent circuit method suitable for high-frequency usage is explained in this chapter. This equivalent circuit is based on the ladder network originally proposed by Wilhelm Cauer (1900–1945) in the field of network synthesis. This method enables significant reduction of computations and also enables coupled analysis of magnetic field and electric circuit. Models for the magnetic sheet and magnetic wire with cylindrical shape are presented. Moreover, the universal method for modeling of arbitral eddy-current fields is introduced.
