The course provides advanced knowledge of power semiconductor devices, power electronic converters, and their industrial applications. The course follows a modern approach, starting from the basic element represented by a half bridge. From this, many modern converters are then developed, each associated with real applications.
Course Prerequisites
Basic knowledge of mathematical analysis and physics. Knowledge of the basic elements of the theory of passive linear networks. Fundamental principles of electrical engineering
Teaching Methods
42 hours of theory lectures, 8 hours of exercises, 2 hours of laboratory
Assessment Methods
The exam consists of an oral test covering the entire syllabus and on the discussion of a project to be developed with a PLECS simulation, which will be assigned during the first weeks of the course.
