EMI circuit modeling of a power train on composite ground plane

The aeronautics world is in continuous evolution. Actually, the tendency is to substitute the hydro mechanical actuators with electrical ones. However, this means introducing more power electronics and in doing so, the systems become more and more vulnerable to electromagnetic noise emitted. Moreover, the introduction of composite material based structures modifies ElectroMagnetic Interference (EMI) behavior in airplanes. The aim of this study is to be able to predict, via modeling, for frequencies ranging from 10 kHz to some MHz, the propagation pathways and the amount of common mode (CM) and differential mode (DM) current. Thus, the model developed as well as the optimization methods can benefit the aeronautical industry during preliminary phases of development of different equipments.
