Mitigating Radiated Emissions of Power Feeders On-board Electric Aircraft

The implementation of all-electric aircraft (AEA) will face several engineering challenges mainly due to its high power requirements. At its core lies the electric powertrain, consisting of the battery, inverter, and motor. Non-ideal behavior of components, cables, and other structures will act as a propagation path for Electroagnetic Interference (EMI). The analysis of EMI in the design phase is considerably complicated due to structural and geometric design, thus, hard to predict. This paper is a first step towards proposing the attenuation of radiated emissions from power feeders by optimizing the switching behavior of converters. Thus, contributing to the overall attenuation level and reducing the performance requirements of power line filters.
