Applications of equivalent cable bundle method in frequency domain for emission problems of the computer case cable harness

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.

<div class="section abstract"><div class="htmlview paragraph">The electromagnetic compatibility problem of the permanent magnet synchronous motor (PMSM) has become increasingly prominent with its continuous development to high power and high torque. To solve this problem, this paper adopts a method based on the establishment of body structure and windings of the PMSM to analyze its electromagnetic radiation (EMR). The radiation stimulus source is acquired by establishing the control model of the PMSM drive system under different driving conditions in Simulink and Carsim. The EMR model of the whole vehicle is established in FEKO by creating winding models and importing three-dimensional (3D) mesh models of the vehicle body and PMSM. The field circuit co-simulation and transmission line method are used in this paper. Finally, we can obtain the electric field radiation strength at different detection points under different driving conditions. The simulation results correspond with the EMR theory and electromagnetic shielding theory. It plays a leading role in the EMR analysis of the PMSM drive system in an electric vehicle.</div></div>
