Electromagnetic compatibility

  • Course level: Beginner

Description

Electromagnetic compatibility. All systems that generate or consume electrical energy can produce electromagnetic noise that may interfere with the operation of the system itself and/or other systems.

Electromagnetic interference (EMI) is a potential threat to present-day electronic devices. The course shows the students how the principles of electricity and magnetism can be applied to design electrical and electronic systems that can co-exist harmoniously, that is, to design systems that are electromagnetically compatible with each other. The students will learn how electromagnetic disturbances are generated in systems, how they couple with other systems, and how systems can be protected.

What Will I Learn?

  • Week 4: EM topology & grounding
  • Week 5: EM Shielding
  • Week 6: Surge protection and filters
  • Week 7: Problem of Intentional electromagnetic interference, Lightning protection
  • Week 8: EMC measurements and Standards(The course also includes some lab work which will be shown as demonstrations).
