INDUSTRIAL ELECTROMAGNETIC COMPATIBILITY

The industrial electromagnetic compatibility is based on the study of the effects of electromagnetic fields created by electrical devices and on the design of systems to reduce their impact on themselves, on other devices or on human beings.

Knowledge and understanding.
The aim of the course is to provide basic knowledge on analytical models and technical aspects related to electromagnetic compatibility (EMC): radiated and conducted emissions, crosstalk, electromagnetic shielding, EMC governmental European requirements for commercial products, EMC measurements for verification of compliance, system design for EMC.
In the laboratory, then, the student will acquire the ability to use software for the numerical solution of electromagnetic field problems by simulating simple devices that are sources of electromagnetic disturbances and applying the related solutions to reduce them.

Applying knowledge and understanding.
At the end of the course, the student will have an overview of the problems related to the design of electromagnetically compatible devices and the main solutions that he can apply to solve them.

Making judgments.
The student will be able to critically observe an electromagnetic device from the point of view of its electromagnetic compatibility and to autonomously assess, already in the design phase, the presence of possible sources of electromagnetic disturbances. This capability is enhanced thanks to the possibility of predicting the electromagnetic behavior of the device through the use of numerical simulations.

Communication skills.
The student will acquire the technical language of electromagnetic compatibility. They will also be able to communicate the design choices made for the reduction of electromagnetic disturbances. The oral exam will allow students to refine their technical language and communication skills.

Learning skills.
The student will be able to learn the causes and solutions of industrial electromagnetic compatibility problems by studying the recommended texts and teaching material provided. Furthermore, thanks to the peculiarity and transversality of the topics covered, the student will improve the ability to study the various topics while maintaining an interdisciplinary vision.
