Lectures and tutorials, laboratory work including simulation exercises.
Written exam (3 credits), laboratory exercises (2 credits).
If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
Cannot be included in the same degree as 1TE300 Power Electronics.
