Abstract: This article conducts a comparison study of the different feasible approaches that are available for implementation of the first-order approximation of a nonlinear eddy current field using the Cauer ladder network (CLN) method. The study comprises a comparison of the different definitions used for the reluctivity, the circuit equations, and the various saturation indexes used in the different approximations. A nonlinear laminated iron core is selected as an appropriate numerical example. Comparisons are carried out with sinusoidal and pulse excitations at high frequencies.
