Identification des perturbations CEM conduites dans les convertisseurs statiques par la méthode du filtre de Wiener

TL;DRAbstract

This thesis uses rather conventional signal processing techniques (wiener filter) in order to reconstruct conducted ElectroMagnetic Interferences (EMI), originate by a power electronics converter. This work allows a better understanding of the origin of the disturbances of such complex systems, and may allow a better design of these converters, concerning particularly control laws, and switching modes. The proposed method has been developed and validated on a simple boost structure. It has then been applied to a voltage inverter, using PWM, PDM and finally using resonance
