Popis: 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.
