Oral exam or an exam in the form of a technical report referring to design, testing and description of a power electronic circuit.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

1. classify the terms in conversion technique regarding their importance in the process of understanding power frequency conversion

2. choose models of conversion components of a PES for a sufficiently accurate and mathematically less demanding analysis

3. evaluate power electronic converters (PEC) with respect to indicators of power conversion quality

4. expound the basic connections as well as cascade connection of PEC on their subsystems

5. identify the individual types of PEC ( DC/DC converters, rectifiers, inverters) from the example of practice
