Description:
The use of a fixed forward power as obtained during the calibration phase in a bulk current injection test, without monitoring the current, may cause damage on the equipment under test (EUT) with low impedances. In this paper, an accurate EUT model has been designed based on impedance investigation. This model can be used to predict the conducted susceptibility of a generic EUT. The model is first based on black-box approach; then, an interaction model is added to provide flexibility of several geometric parameters, which can be changed from one setup to another. This methodology leads to the combined approach, which shows a satisfactory agreement between simulations and measurements. According to the developed equations, the impedance matrix of the described model can be readily switched to modal one. Afterward, asymmetric dummy EUTs were investigated and the analytical equations used to predict differential mode due to common-mode voltage injection were validated.
