Investigation of Conducted Noise Impact on Conducted Susceptibility Testing for a Wireless Power Transfer System with Bifurcation Phenomena
This paper presents the modeling of bifurcation phenomena in a wireless power transfer (WPT) system along with its application in the testing of conducted susceptibility (CS). The presented model represents an analytic transfer function based on the equivalent circuit models of strongly coupled coils, and its validation was performed using a simple WPT system designed and fabricated as equipment under test (EUT). Additionally, experimental verification of effectiveness of the presented model was performed via transfer-function measurement. The presented model was applied to estimate the impact of conducted noise on measurement-based CS testing of WPT systems demonstrating bifurcation phenomena. Results obtained in this investigation demonstrate that the impact of conducted noise with bifurcation phenomena can be successfully estimated using the presented model.
