Research the Radiated Electromagnetic Interference from Power Converters under Operating Conditions

Noise immunity issues are always a potential problem for the reliable functioning of control and automation systems. Modern electronic devices generally meet the requirements for electromagnetic interference when considered separately. But usually they are part of the control system in a complex technical facility. Then undefined ways and mechanisms of interaction of interferences from various systems may arise. The article proposes a technique and means for research radiated electromagnetic interference from power converters under operating conditions. As an example, the application of the created tools for a switching power supply is considered. The conclusions are presented on the basis of the analysis of the obtained results.
