—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)
The subject of this paper is related to EMC filter integration. Due to stray interactions between filter components and PCB tracks, or between the components themselves, the transfer function of the filter can be modified. The work will first study these stray interactions and the possible electromagnetic modelling using PEEC method. Then, we aim proposing(More)
The emergence of new composite materials in the aeronautical domain requires a paradigm shift in the electrical system design, especially concerning the current return path. The composite fuselage cannot comply with the required functionalities, as the aluminium skin does, due to its heating and conductive natural limitations. The aim of this paper is to(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 a full partial equivalent electrical circuit (PEEC) model of an electromagnetic compatibility (EMC) filter, including the discrete components as well as the interconnection models. Therefore, the complete behavior of the filter is taken into account, including all magnetic stray elements (inductance and couplings). This model is(More)
The transfer function of an EMC (Electo-Magnetic Compatibility) filter can be strongly disturbed in high frequency (HF) due to all the magnetic and electrostatic imperfections. Some of them are specific to the discrete component geometry, and the others comes from stray couplings between every element of the system (as tracks well as components themselves).(More)
This paper presents a solution to reduce common mode current generation in the low frequency range (from switching frequency up to few MHz). It is based on an active solution, which only uses the components that are present in power modules. The principle is simply to generate a common mode current, opposite to the one generated from the power module.(More)
