Abstract(s)

The study of Electromagnetic Compatibility (EMC) has, since 1990 [1] [2] presented greater evolution. However, due to costs of measuring equipment for measuring the Electromagnetic Interference (EMI) generated and propagated from equipment under test (EUT), a number of educational institutions cannot ou have difficult in teaching the phenomena associated to EMI generation, propagation and mitigation. Therefore, in last years, teachers of the EMC subject in Electronic Engineering and Technology in Electronic Systems courses of the Department of Electronics of the Federal Institute of Santa Catarina have developed experiments that allow the study of EMC/EMI using simulator software packages and usual bench equipment as oscilloscopes and signal generators. This work intend to present practical experiments that enable to the undergraduate students the observation of concepts and techniques associated to EMC and EMI, without concerns with a controlled environment, neither with the precision at the measuring of the induced voltage levels. The aim is to present the qualitative aspect and compare the results for certain situations.
