Learning outcomes and competences
At the end of the course unit the learner is expected to be able to:
1. Understand the fundamental characteristics of the power semiconductor devices widely used in power electronic converters applications;
2. Understand the operation of AC/DC power converters (rectifiers) – controlled and non-controlled, single- and three-phase – and compare their effects to the grid;
3. Understand the operation and the basic control techniques of DC/DC power converters – step-down (Buck), step-up (Boost), and Buck-Boost and full-bridge;
4. Understand the operation of DC/AC power converters (voltage source inverters) – single- and three-phase – the basic control techniques, and the output harmonic
spectrum;
5. Simulate and analyse the operation and control of the basic topologies of power electronic converters;
6. Analyse small power applications in the laboratory.

Course contents
General description of power semiconductor devices. Introduction to power electronic converters: converters from direct current to direct current (DC/DC) – stepdown (Buck), step-up (Boost), and Buck-Boost and full-bridge; converters from direct current to alternating current (DC/AC) – single- and three-phase voltage source
inverters; AC/DC converters – single- and three-phase diodo and thyristor rectifiers.
Course contents (extended version)
1. Fundamental characteristics of the main power semiconductor devices as electronic switches:
