Abstract

In this paper, SPICE behavioral modeling of injection probes for bulk current injection (BCI) is addressed. The implementation procedure is based on preliminary experimental characterization of the frequency response of the probe core via measurement of the probe input impedance. Two alternative solutions are proposed for the inclusion of frequency-dependent core-related effects. The first solution directly embeds measurement data of the effective permeability spectra of the ferrite core in a SPICE behavioral module; an alternative solution employs a Lorentzian model. Models accuracy and effectiveness are assessed by comparing SPICE predictions of a simplified BCI setup with experimental measurements. 1.
