Abstract

The coexistence of electronic power and control systems in the same box presents a serious threat to the proper functioning of electronic systems integrated into automobiles, aeronautics and space. Thus, managing the electromagnetic compatibility of these systems constitutes a challenge, particularly given electromagnetic phenomena. This paper describes a simulation study and application of the partial element equivalent circuit method to model the prediction of radiated emissions from the onboard electronic cable system. In this article, we first explain the use of the partial cell equivalent circuit modeling method, then describe its mathematical formulation and introduce the different electromagnetic phenomena it considers in connection with wiring, then propose radiation calculations electromagnetic as a function of the geometry of the discrete cells taking into account the increase in frequency. The goal is to get as close to the structure as possible. To balance the accuracy and speed of the proposed method, we replaced the partial capacities with the equivalent capacities so as to considerably minimize the number of capacities, the complexity of the system and the computational time requirement. This option adapts the partial element equivalent circuit method to the study of larger structures such as cable structures and provides an efficient and rapid way to simulate electromagnetic radiation. To achieve this objective, we have associated the physical laws of electromagnetic wave propagation with the method of modeling equivalent circuits using partial elements because it is easy to manipulate flat surfaces and cables. 2D simulations based on the proposed models were developed as well as the verification of the consistency of the different models, by comparing the fractal dimensions of the program results with those of the figures obtained experimentally.
