“…For the simulation study, not only the devices have to be taken into account. A realistic model for EMC must be identified for the passive and the parasitic elements [1,2]. In order to predict compliance to EMC standard, a LISN (Line Impedance Stabilization Network) must be included in the model.…”

Abstract-In this paper, the EMC behaviour of a switching cell is studied in a standardized environment, using both experiments and simulations. The environment model has been validated separately. The EMC emission using SiC JFET and Si MOSFET are compared. With the SiC JFET the simulation study shows a good agreement with the experiment up to 20MHz while with the Si MOSFET the validity domain of the model is less than 500kHz due to the simplistic model included in the SABER library. The experimental study shows that the EMC perturbations measured at the LISN are 10dB larger with the SiC JFET than with the Si MOSFET at a frequency range from 200kHz to 4MHz.

This study analyses electromagnetic interference (EMI) noise sources generated from a new type of flyback converter which is operated from a self-supplied power control integrated circuit (IC). On the basis of analysis, a new analytical mathematical model of common-mode (CM) EMI noise path is presented. This model is easier to construct and allows researchers to better understand the impact of each parameter on CM EMI noise than former models. According to the proposed model, the capacitors from the traces connected to the ground (GND), voltage drain drain (VDD), current sense (CS) and feedback (FB) pins to the ground demonstrate the greatest impact on CM EMI. Two improved layouts are designed to verify the analysis result. The layouts were driven by the newly developed model. Test results show that they correspond with theoretical calculations supporting the analysis and the model that was developed in the course of this work.
