A Generalized Multiple-Scattering Method for Modeling a Cable Harness With Ground Connections to a Nearby Metal Surface

Introduction. In this paper, the equivalent cable harness method is generalized for predicting the electromagnetic emissions problems of twisted-wire pairs. The novelty of the proposed work consists in modeling of a multiconductor cable, in a simplified cable harness composed of a reduced number of equivalent conductors, each one is representing the behavior of one group of conductors of the initial cable. Purpose. This work is focused on the development and implementation of simplified simulations to study electromagnetic couplings on multiconductor cable. Methods. This method requires a four step procedure which is summarized as follows. Two different cases, of one end grounded and two ends grounded configurations can be analyzed. Results. The results had shown that the model complexity and computation time are significantly reduced, without, however, reducing the accuracy of the calculations.

“…On the other hand, it is known that the twisted wire pair (TWP) cables can reduce the external coupling due to its special structure, and they are widely used in many communication systems 1–4 to reduce external or internal electromagnetic interferences (EMI). More recently, numerous susceptibility studies have been conducted on TWP cable systems exposed to different electromagnetic plane wave excitations, 5–10 and further, these studies are generalized to be applicable to multi‐twisted structures 11–13 . It has been found that the twisting structure of the cable provides significant benefits in reducing external EMI.…”

In this article, deep neural network (DNN) and chain parameter methods are used to analyze the crosstalk coupling of a star‐quad and a twisted bundle of twisted wire pairs (TBTWP) cables for different excitations, respectively. A DNN is used to extract the per‐unit‐length (p.u.l) resistance, inductance, capacitance, and conductance (RLCG) parameters at any position for the star‐quad and TBTWP cables. The induced common mode (CM) and differential mode (DM) currents due to crosstalk are calculated by combining the obtained RLCG parameters with the chain parameter method. The obtained results show good agreement with that of FEKO software. Moreover, it is found that the star‐quad cable can reduce the external coupling more effectively than that of the TBTWP cable. Finally, measurements are performed to further validate the accuracy of our proposed algorithm.

“…With the increasing frequency and integration of current power equipment, the problem of crosstalk between transmission lines cannot be ignored [1], [2]. Crosstalk is an unintentional coupling phenomenon, which means that the electromagnetic field generated by the voltage and current on the excitation line will affect the adjacent transmission lines and generate induced signals at their endpoints [3].…”

“…In [8], a new non-uniform TWP modeling method is proposed to simulate the change of the center position of the TWP. G. Spadacini et al proposed a prediction model of low-frequency nonuniform TWP crosstalk under plane wave excitation [1][2]. The equivalent cable bundle method (ECBM) is used with some modifications to predict crosstalk within a bundle of TWP [11].…”

In this paper, a new algorithm for predicting per unit length (p.u.l) parasitic parameters of transmission line is proposed. In the twisted-wire pair (TWP), different rotation degrees correspond to different parasitic parameters, which brings difficulties to the solution of telegraph equation. At present, the mainstream method is to divide TWP and use the cascade theory to solve each segment as a parallel transmission line. Therefore, we propose to use the beetle swarm optimization (BSO) algorithm to optimize the weights of the back propagation neural network, use a certain sample to train the network. This algorithm is used to predict the p.u.l parameters of uniform and non-uniform TWP, and the finite-difference time-domain (FDTD) method is used to solve telegraph equation. Among them, the crosstalk value of the uniform TWP is compared with the simulation value in the CST to verify the effectiveness of the proposed algorithm; the non-uniform TWP performs 500 random generation calculations to give the maximum envelope value of the crosstalk.INDEX TERMS Beetle swarm optimization (BSO), crosstalk prediction, finite-difference time-domain (FDTD), multiconductor transmission lines (MTL).
