Power Electronics


Educational goals

The purpose of the course is the student to understand the particularities of electronic power circuits, the functional behavior of ideal and real semiconductor switches, and the principle of operation of power circuits with alternating current input. The specific objectives of the course are that the student can:

  • Remember, reproduce, analyze, and apply knowledge from DC circuits and AC circuits lessons.
  • Recognize and demonstrate the particularities of power converters.
  • Evaluate, compare and select the most suitable power switch for each application.
  • Recognize, describe, and interpret the operation of power converters.
  • Evaluate and select the most appropriate power circuit, depending on the application.
General Skills
  • Search, analyze and synthesize data and information, using the necessary technologies.
  • Decision making.
  • Independent work.
  • Teamwork.
  • Exercising criticism and self-criticism.
  • Promoting free, creative and inductive thinking.

Students evaluation

Written final examination, which is in the form of problem solving with distinct difficulty and the free use of any help.

The grade on the written final examination must be at least five (5.0).

The evaluation criteria are notified to the students through the course web page and also during the lectures.
