Aim

EMC - ElectroMagnetic Compatibility - means that electrical equipment must be able to function as intended without interfering or being interfered by its environment. The minimum requirement is defined by the legislation. Knowledge within this area is essential for everyone that will be active as a designer of electronic systems. The course is intended to give the students a fundamental understanding of how electromagnetic noise is generated and how it affects electronic systems and how it can be reduced to avoid malfunction of the systems. An overview is also given of the standards and directives that are mandatory to be fulfilled by electronic equipment

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• Be able to identify different sources and coupling paths of electromagnetic noise.
• Be able to analyse and suggest suitable measures to avoid interference.

Competences and Skills

For a passing grade the doctoral student must

• Be able to design a simple electronic system where the EMC requirements are fulfilled.
• Be able to perform basic EMC measurements and evaluate those.
• Be able to sort out and acquire information from a comprehensive material, e.g. a text book or lab exercise material, with limited reading instructions.
• Be able to orally and in writing communicate and discuss the results of a project.

Judgement and Approach

For a passing grade the doctoral student must Have realised the importance of taking EMC aspects into consideration throughout the complete design process of electronic systems
