The course of Power Electronics I consists of the following
1. Power Semiconductors: Types of power semiconductors used as
switches in Power Electronics systems (e.g., diodes, thyristors,
MOSFET, IGBT, etc.). Operating characteristics, uses, loss
calculation, benchmarking.
2. Uncontrollable Rectifiers: Single-phase, three-phase, output
voltage smoothing, harmonic analysis, transition effect.
3. Controllable Rectifiers: Single-phase, three-phase, DC / DC,
harmonic resolution, transition effect, power reversing function
4. AC-AC Converters: a) AC regulators: Single-phase-three-phase,
analysis, applications, b) Circuit converters

Learning Outcomes:

The aim of the course is to introduce the student to the theory and applications of power electronics systems. In the first part of the course, 2 categories of electronic power converters are studied: rectifiers (AC-DC) and AC-AC converters.

Upon successful completion of the course the student will be able to:

• Identify, compare and describe the main power semiconductor devices, while the student should also calculate their losses;

• Understand and explain the principles of power electronics;

• Explain in detail the basic functions of the different types of power converters examined in the 1st part of the course;

• Compare and evaluate the individual circuits of each type of power converters;

• Implement experimental devices in the laboratory and analyze their operation;

• Simulate and explain the operation of basic power converters;

• Design power converter circuits belonging to the categories of AC-DC and AC-AC converter;

• Use the knowledge acquired to understand converter topologies in practical applications;

• Collaborate with his fellow students to prepare teamwork essays.
