A current transformer modeling
Yann Le Floch, Christophe Guérin, Dominique Boudaud, Gérard Meunier, Xavier BrunotteThis paper presents the modeling of a current transformer by various methods with the FLUX3D software. The technique used is based on the finite element method coupled with…
Achieving the holy grail of seamless CAD data import into analysis software
J. Oakley, C.P. Riley, S. Taylor, C.W. TrowbridgeOne of the difficulties in electromagnetic modelling has been the lack of standard CAD data to enable direct import of data into analysis software. Many solid modelling standards…
Application of regularisation method of quasi‐singular integrals to compute eddy current distribution near cracks
Philippe Beltrame, Noel BuraisFor thin cracks, in eddy current testing (ECT), the field‐flaw interaction is equivalent to a current dipole layer on its surface. The dipole density is the solution of an…
Design of photonic band gap optical fibers using finite elements
S. Guenneau, S. Lasquellec, A. Nicolet, F. ZollaIn this paper, we study a new class of optical fibers to be utilized in future optics and optoelectronics. These so‐called photonic band gap (PBG) waveguides can be classified…
Analysis of techniques to compare complex data sets
D.E. Coleby, A.P. DuffyThis paper analyses a number of techniques that can be used to compare complex data sets, such as those arising from electromagnetic simulation and experimentation. The techniques…
3‐D eddy current computation for a transformer tank
Hiroshi Kanayama, Ryuji Shioya, Daisuke Tagami, Satoshi MatsumotoA large scale computation of three‐dimensional eddy current problems is considered; their numbers of degrees of freedom are near one million. A parallel computing using the…
Integration of control loops in coupled field circuit model to study magnetic devices supplied by power electronic converter and their control
G. Manot, Y. Lefèvre, H. Piquet, F. RichardeauIn this paper, we present a method to take into account the feedback control in software developed from coupled field circuit models. The implementation of control loops is done…
Calculation of winding losses using matrix modeling of high frequency transformer
K.W.E. Cheng, K.F. Kwok, S.L. Ho, Y.L. HoCalculation of the winding losses of high frequency transformer based on one‐dimensional field analysis is normally inapplicable for complex winding configurations. This paper…
Eddy currents in thin plates modelled as surface regions
Virgiliu Fireteanu, Bernard Paya, Jacques Nuns, Tiberiu TudoracheThis paper analyses the conditions for which the results of eddy currents computation in thin regions modelled by surface regions are concordant with those obtained using volume…
Field and current flow analysis of the buried feeding line of the innovative electric transport concept STREAM
P. Alotto, F. Delfino, G. Molinari, M. Rossi, V. Siciliano, P.O. VenturaSTREAM is the acronym of a new concept of mass transit system designed and developed by Ansaldo Trasporti S.p.A. to provide an efficient solution to rubber‐tyred transportation…
Developments of an efficient global optimal design technique – a combined approach of MLS and SA algorithm
S.L. Ho, Shiyou Yang, Peihong Ni, H.C. WongA new response surface model (RSM), the moving least squares (MLS) approximation, is proposed for reconstructing the objective/constraint functions for the design optimization of…
Magnetic field around the aluminium electrolysis cells
Augustin Moraru, Aureliu Panaitescu, Ileana Panaitescu, Antoineta SociTwo magnetostatic applications are reported, related to the magnetic field around the aluminium electrolysis cells. The first exhibits the magnetic field created by the current…
3D‐FDTD characterization of an original low‐loss silicon line
Alexandre Richardson, Laurent Cirio, Laurent Martoglio, Odile PiconA numerical and experimental analysis of an original inverted microstrip transmission line on standard Silicon substrate for telecommunication applications is proposed…
