Etude des perturbations dans les convertisseurs de l'électronique de puissance

Abstract : The goal of our thesis is the characterization of the electromagnetic environment of the power electronics converters. In this intention, by using analytical formalisms for the calculation of the electromagnetic field, we propose to model the electromagnetic radiation of the power electronics devices in frequency domain and also directly in time domain. After an analysis by direct resolution of the Maxwell's equations by FDTD, we extended our work to a simplified approach and more accessible to the engineer of research. This approach consists in two steps. In a first step, we start with the calculation of the currents and voltages distribution. In the second phase, we treat the analytical calculation of the emitted electromagnetic field. In order to complete our work, we have also been interested to the reduction of the electromagnetic emission of the power converters. For these problems, we propose to reduce the radiated magnetic field by introducing passive conducting loops within the device.
