Etude des perturbations électromagnétiques rayonnées par des composants magnétiques planaires intégrés : inductances

Abstract : Nowadays, the development of complex electronic systems consists of embedding several components in a single box generates more and more electromagnetic disturbances. The magnetic component such as inductor, is referred as the most disruptive component because of its EM emissions. The presented works in this document concerns the study of EM disturbances in radiated emission of 3 types of inductors: coreless, inductor with one and two layers of magnetic material. This manuscript, presents our scientific contributions that allow to:- Quantify through simulation and measurement, the near field radiated emissions of theses inductors;- Limit these electromagnetic emissions by using magnetic shielding;- Evaluate the influence of some parameters such as: relative permeability µr and the magnetic shielding thickness on the limitation of components emissions.The obtained results in measurement and simulation, present very good correlations.
