Investigation EMC compliance with Aircraft Communication System and switch-mode power supplies

o In this paper, investigation EMC compliance with Aircraft Communication System is discussed. o Switch-mode of power supplies can produce electromagnetic interferences, because signal of communication system can interfere with high-harmonics of power switching. o The interferences can be floating, what is unpleasant effect in cases for of VSCF power systems. o Testing EMC procedures and provides a comprehensive review of power electronic effects. o The proposed test-arrangement of the two-signal tests have been experimentally verified and shown in this paper
