EMC studies on systems with hybrid filter circuits for modern aircraft applications

[摘要] In this contribution, a new approach for EMC-filter design is presented. Dueto the increasing electrification of modern aircraft, as a result of the MoreElectric Aircraft concept, new strategies and approaches are required tofulfill the strict EMC aircraft standards (DO-160/ED-14 – Sec. 20).Consequently the weight and volume of the used filter components can bereduced. A promising approach could be a combination of passive and activefilters. For the same attenuation effect, so-called hybrid filters achieveeither savings in weight and volume, or can obtain an additional filteringeffect with minimal weight increase of an existing system. In this paper, theunderlying theory is explained in detail, carried out in a simulation tooland the gained insight is demonstrated with a sample measurement.
