Investigation EMC compliance with aircraft communication system and switch-mode power supplies

Our intention in this paper is to highlight testing for electromagnetic compatibility (EMC) compliance with military airborne communication system and switch-mode power supplies. Power supplies using technology of high-frequency switching provides the interface between an electrical source and electrical appliances. These power electronic sources can product electromagnetic interference to cause subinterval interference to the other electrical devices such as airborne communication system or control system. Briefly, power electronic circuits of power processing that are typically in use in power process of sources are shown. In this paper, practical results of EMC investigation will be shown and discussed.
