—Design of integrated power systems requires prototype less approaches. Accurate simulations are necessary for analysis and verification purposes. Simulation relies on component models and associated parameters. The paper focuses on a step-by-step extraction procedure for the design parameters of a one-dimensional finite-element-method (FEM) model of the(More)
— Volume integral formulations for solving electromagnetic problems in the frequency domain are proposed. Firstly, it is based on a magnetic flux B and current density J facet interpolation for representing the electromagnetic problem through an equivalent circuit. Secondly, magnetic vector potentials A and electric vector potential T are considered thanks(More)
In order to compute electromagnetic problems in presence of thin conductive and magnetic shells, a new integral formulation is proposed. Based on the principle of shell element, the formulation is general and enables the modeling of various problems for any skin-depth, avoiding the air region meshing. The formulation is validated thanks to an axisymmetric(More)
    This paper presents an application of an adapted (R-L-M-C) PEEC method dedicated to the extraction of equivalent circuit of power electronics devices. Two dedicated integral methods with different meshes are used to compute either resistive and inductive elements or capacitive couplings. The adaptive multi-level fast multipole method (AMLFMM) is(More)
    Ce papier porte sur les travaux d'extraction de capacités parasites pour des structures d'électronique de puissance. Celles-ci sont calculées à l'aide de la méthode des moments ou de la méthode rapide multipolaire. Ces méthodes sont utilisées pour modéliser un convertisseur statique et les calculs de capacités sont confrontés à des mesures et à une(More)
— This paper address some problems linked to the physical layout of high current rectifier: paralleling components, magnetic field close to the rectifier and also the validation of the physical layout at reduced current. Even if the impact of cabling stray inductance is well known, some new tools and methodology are today available to design quicker and(More)
