Learning outcomes
|
The course expands the student's knowledge in the areas of EMC standards, industrial sources of interference and the types of couplings through which interference is transferred. In addition, students get acquainted with selected chapters of electromagnetic field theory. Emphasis is also placed on the analysis of galvanic, capacitive, inductive and radiation (electromagnetic field) coupling. Subsequently, students get acquainted with frequency planning and laboratories for electromagnetic compatibility measurement. In the last part of the course, the testing of the electromagnetic susceptibility of systems, improving their resistance to interference and ways to the interference elimination will be introduced to students. The course is extended by the interpretation overvoltage protection, of interference factors and EMC in the case of UWB.
The students will get the skills to define and modify the electro-magnetic susceptibility, and measure the susceptibility and interference.
