This report concerns the determination of the parameters R and L of wound materials at high frequencies with the 3D finite element method. The work are focus on the power transformers.The work carried out consisted in developing a method allowing to free oneself from the eddy currents calculation by finite elements. That led to the concept of magnetic permeability complex. By the use of a magnetic scalar potential formulation and the complex permeability was possible to set up a method of determination of the caracteristic parameters of a power transformer. Parameters in matric formwhich will be used for simulations electrical supply network.Cette thèse concerne la détermination des paramètres R et L de matériels bobinés à hautes fréquences...
