The 'Equivalent Cable Bundle Method': an Efficient Multiconductor Reduction Technique to Model Industrial Cable Networks

Application of the "Equivalent Cable Bundle Method" for Modeling Crosstalk of Complex Cable Bundles Within Uniform Structure With Arbitrary Cross-Section

“…In this section, compared with previous papers [1][2][3][4][5][6][7][8][9], the differences and also the challenging points of the proposed method are the grouping of conductors and the building of the cross-section geometry of the reduced cable bundle model, which are detailed in the following paragraph. As far as the EM crosstalk is concerned, the approximate assumptions including a) all conductors are PEC and the surrounded medium is lossless, b) only transverse electromagnetic (TEM) mode is considered.…”

“…Up to now, the establishment of the reduced cable bundle cross-section geometry only can be implemented either above an infinite PEC ground plane [2][3][4][5], inside a cylindrical cavity [6] or in the vicinity of a 60 degree corner [8] through the analytical formulas. However, no analytical formulas are available for direct reconstruction of the reduced cable bundle cross-section geometry model within arbitrary complex structures as Fig.…”

“…It was first developed for calculating the common-mode current induced at the extremity of simplified point-to-point cable structures excited by various incident electromagnetic (EM) fields [1], and also has been successfully extended for emissions [2,3] and crosstalk [4] problems of complex cable bundles over a large frequency range with some reasonable modifications. Moreover, it was modified in [5] for modeling EM field coupling to the twisted-pair cables based on the assumption that the differential signal lines play a leading role in the equivalence procedure.…”

Multiconductor Reduction Method for Modeling Crosstalk of Complex Cable Bundles in the Vicinity of a 60 Degree Corner

“…Meanwhile, in order to make the problem simpler, we only consider real loads at the two terminals of the cable bundle, which are listed in Table 1. The common-mode characteristic impedance Z mc which can be determined by modal analysis [8] equals 90 Ω. According to the grouping process in Section 2, the conductors of the cable bundle can be sorted into four groups as follows.…”

“…emissions [7,8] and crosstalk [9,10] of complex cable bundles over a large frequency range with some specific adjustments. It has also been adapted to predict the crosstalk of a cable bundle in the cylindrical cavity which is considered as the ground return [11].…”
