Summary
The topic of this subject extends the previously obtained knowledge of the power electronics based especially on already known basic function principles of rectifiers, voltage converters, inverters, frequency converters and the driving methods of these devices.
This subject is focused to get the cognizance in details of modern power switching devices including application rules of this devices, and it explores the knowledge of power semiconductor systems. The learning process extends the general orientation in the field of analogue electronics and electrical engineering.
Knowledge obtained in this subject offer students good orientation in the branch of power electronics applications, e.g. applications with UPS, welding power sources, AC power regulators and in applications with electrical drives. This subject enables students to explore parts of power semiconductor systems and to apply obtained information within constructing in practice. Knowledge obtained in this subject are a part of a general knowledge of electrotechnical educated expert.

Additional study materials
Way of continuous check of knowledge in the course of semester
Verification of study:
Checktests TEST no. 1, TEST no. 2 (s. exercises)
Conditions for credit:
100% practical instruction participation. Extraordinary substitute just on the base of previous teacher acceptance.
Delivering of practical instruction course works on schedule = 1 week after appropriate practical instruction
100% check tests participation on schedule (exact date will notice minimal 1 week before). It´s possible to repeat each check test one time. In case of repeating check test it´s possible to obtain just 80% of conventional maximal amount of points!
Minimal amount of received points is 25 from 40 points.
Points classification of practical instructions - maximal 40 points, divided to:
T1 = max. 10 points
T2 = max. 10 points
Course works of practice instructions = max. 20 points
