Full-wave modeling of bulk current injection probe coupling to multi-conductor cable bundles

Abstract

A model was developed to represent a bulk current injection (BCI) probe used for EMC testing. This model physically represents the BCI probe which allows one to model the coupling to multiple wires simultaneously. This model has many useful applications in designing products that comply with BCI test standards and to gain insight on BCI testing principles. The effect of changing individual wire termination impedances and differential bulk current injection will both be presented using this model.
