Learning Outcomes
The anlaysis and design of electric and electronic devices and equipment in a manner that makes them immune, as possible, to electromagnetic interference (EMI) while at the same time prevents the equipment to produce signals capable to interfere to other systems .
Course Content (Syllabus)
Section 1 (2 hours) Introduction
- Electromagnetic Interference (EMI) sources and examples.
- Basic parameters of interference and EMC quantities.
- International recommendations– regulations and standards concerning EMC problems handling.
Section 2 (6 hours): Mechanisms of EMI generation and Methods of shielding
-Shielding from magnetostatic and electrostatic fields
– Plane wave shielding techniques
– Interference from ‘near’ electromagnetic field of high and low impedance
– Analysis and study standards of the EMI of external fields through apertures in the metal cover of devices and techniques of mitigation .
Section 3 (7 hours):EMI among the electronic units in the internal of a device and techniques of mitigation
-Time and Frequency Domain analysis and study of the crosstalk between signal transmission lines, due to electromagnetic coupling at low and high frequencies.
- Building rules of lines to minimize interference.
- Basic EMC rules – guides for PCB design.
- Switching noise. Phenomenon and mitigation techniques.
Section 4 (11 hours) EMC measurements
– Installation specifications – measurement equipment and limits
– Open Area Test Sites (OATS) and Chambers (anechoic, TEM, GTEM, resonance)
– Radiated Emission Measurements
