Planned learning activities and teaching methods

Lectures are lead with the massive support of Power-Point. The Power-Point file is available for students.
In laboratories, students measure and analyse 4 exercises (transistor power converters) with the help of oscillograph.
In numerical exercises, the typical tasks are solved (design of active and passive elements of power converters).

Assesment methods and criteria linked to learning outcomes

Requirements for completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated for every.
