“…Other approaches with different order of integration have been developed and compared to solve the matrix system (5). In a 0-order Galerkin approach, double integrals are used to compute the coefficient of (6) and the second member of the matrix linear system (6) is multiplied by the element surfaces.…”

EMC Modeling of an Industrial Variable Speed Drive With an Adapted PEEC Method

This paper presents an adapted partial element equivalent circuit (PEEC)-based methodology applied to the modeling of interconnections of power electronics devices. Although this method is already well known, the originality of this work is its use to model a device presenting an industrial complexity. To make possible this modeling, two adapted integral methods, based on two different meshings, are presented. They are dedicated respectively to the computation of parasitic inductances and capacitances and lead to an equivalent circuit of the system. From a time-domain simulation of this circuit, current and voltage sources can be extracted and used to compute the radiated near magnetic field. This approach has been applied to model a real industrial static converter via system couplings, a variable speed drive. Good agreements have been obtained between simulated and measured results on conducted and emitted electromagnetic analysis.Index Terms-Electromagnetic compatibility, fast multipole method, parasitic capacitances, parasitic elements, partial element equivalent circuit (PEEC), power electronics, power interconnections.

“…If elements are not parallel an analytical/numerical integration technique is used (an analytical expression for the first integral is used, the second one being computed thanks to an adaptive gauss point integration ensuring a good accuracy). All values of L i and M ij can then be organized in a dense and square matrix [L-M] whose size is equal to the number of mesh elements (Aimé et al, 2007). The evaluation of the electrical equivalent circuit of the meshed structure has been implemented into the dedicated software InCa3D® which offers a robust and fast solver combined to a user friendly and efficient graphical interface.…”

“…The surface scan is 16 cm x 28 cm to cover all the ASD surface and the near field probe height is settled on 3 cm, in order to be the nearest as possible the components over all the speed drive surface [2], [8]. The H z component of the magnetic field was measured and the obtained mappings are given in Fig.…”

In this paper, the behavior in radiated mode of an EMI filter used in speed drives is analyzed. It was identified as one of the main sources of magnetic near field radiation. On one hand, the EMI filter is located upstream from the speed drive and is the victim of the other radiation sources of the speed drive. On the other hand, these sources excite its parasitic elements and create new resonance frequencies. By analyzing input impedance and transfer function and magnetic field measurements, we tried to link the resonance frequencies of the amplitude spectra of the radiated magnetic field and the one of the electric characteristics.
