N2 - Enabling All-Electric Aircraft (AEA) operations result in considerable EMC compliance challenges. Considering its architecture, secondary distribution systems will eventually interact with equipment not regulated by the DO-160 standard. Portable electronic devices (PEDs) introduced By passengers could result in compatibility issues. In this paper, two approaches were compared when assessing EMI on a parallel multi-load circuit. The conducted emissions of four different power supplies representing PEDs were individually measured, then combined resulting in an equivalent full-load assessment. The same loads were simultaneously measured, representing the in situ test. The differences in EMI levels are presented, depicting inherent harmonic components from each approach. The results are discussed, showing reduction in EMI levels between approaches, which can enable filter design optimization on a component level.
