Abstract

The authors provide a method of evaluating two equivalent lumped capacitances by taking into account the physical effects of the stray capacitances in two coupled inductors. The lumped capacitance values are determined by means of a procedure based on the fitting eigenvalues of two equivalent circuits. The definitions and mathematical theory underlying the method are presented. The measurement system used and the parameter identification problem are discussed. The actual response of the two coupled inductors is compared with the response of the identified model
