In this paper we proposes a synthesis of different mathematical models of power electronic converters based on Thevenin/Norton equivalent circuits. Those models, composed by impedances and harmonic noise sources, are helpful to predict the conducted ElectroMagnetic Interferences (EMI) generated by converters connected to the electrical network. Moreover, the extracted impedances are determining for...

Power by wire concept is a novel trend in modern electrical systems. Hence, system networks have become more and more sophisticated, and their modeling is no longer an easy task. In this paper, we propose an analytical analysis of a global EMC of a modern electrical network. Explicitly, we develop an analytical model to evaluate differential mode impedance at different sites of a complex network....
Common mode and differential mode impedances are crucial for EMC networks modeling and filter design in particular. In this paper, we propose an original analytical model of common mode and differential mode input impedances of a DC-DC converter, including major parasitical elements. This model has been synthesized using basic laws of electrical circuits. The analysis of the converter circuit is achieved...
This paper proposes to investigate the Differential Mode (DM) input impedance of a DC-DC converter. This parameter is crucial for network analysis, in a wide frequency range, from very low frequency for network stability analysis up to several tens of MHz for EMC studies. Analytical approach based on signal processing theory is developed, validated by PSPICE simulations and experimental measurements...
