All-electric aircraft present a new electromagnetic environment in which electromagnetic interference filtering is playing an important role. Together with a maximum take-off weight, the critical need exists for the optimized filtering solutions. A conventional conducted emission test provides insufficient information for the filter design and implementation since it evaluates only normal mode interference and only the total noise that is present in the system can be measured. This paper presents the measurement procedure using multichannel time-domain measurements to evaluate differential and common mode interference that propagate towards both sides of the system in the powertrain of all-electric aircraft. By implementing the described technique, the optimal volume, weight, and placement of filters can be found.

“…However, to obtain the data that will show an actual IL for the specific application the exact terminating impedances, which vary greatly depending on the application, have to be known. For example, in [6] it has been discussed that to achieve a more optimal way in selecting and applying an EMI filter, all the noise sources (e.g. power converters) have to be standardized and classified, after which the optimal filter for each category can be developed.…”

“…power converters) have to be standardized and classified, after which the optimal filter for each category can be developed. As emphasized in [6], this may result in an infinite number of different filters, which will increase the costs, and the development-, testing-, and manufacturing time. Hence, a trade-off between the accuracy of the filter performance for each application and the efficiency of the testing has to be found.…”

Electromagnetic interference filters are being characterized in terms of their insertion loss. CISPR 17 provides measurement procedures for assessing normal, common, and differential mode insertion loss. Respectively, this requires three different setups to fully characterize the filter. This paper shows an alternative to the CISPR 17 setup resulting in a time-efficient measurement approach that allows the evaluation of all modes of insertion loss of the filter in a single measurement setup. Furthermore, it is extended to an approximate worst-case measurement, as in CISPR 17. Complimentary, the suggested setup is used to perform insertion loss measurements of a filter including line impedance stabilization networks, to assess the more realistic performance of the filter in the conducted emission test.
