Examination methods

Oral exam or an additional assignment.

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

Learning outcomes
Upon successful completion of the course, students will be able to:

1. estimate power conversion characteristics of power electronic converter (PEC) components for basic and on a one-time basis connections of a system with different characteristics

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

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

4. evaluate the choice of PEC topology regarding the cascade connection of several converters

5. analyse the basic topologies of DC/DC converters, rectifiers and autonomous inverters
