Summary
Power electronics is a branch which intensively enters all technical areas of the present living. Practical utilization of the conversion principle of the electric energy via semiconductor switching devices requires apart from the knowledge about principle and function of elementary semiconductor converters also especially about their industrial and commercial applications. The subject provides pieces of knowledge to students in field of applied and commercial electronics, power electronics, electric drives and other segments of electrical engineering.
Compulsory literature:
Recommended literature:
Heumann, K.: Basic Principles of Power Electronics. Springer-Verlag Berlin Heidelberg New York, ISBN 3642826768, 2012.
Way of continuous check of knowledge in the course of semester
Verification of study:
Checktests TEST no. 1, TEST no. 2 (see exercises)
Conditions for credit:
100% practical instruction participation, extraordinary substitute just on base of previous teacher acceptance.
Delivering of practical instruction courseworks on schedule = 1 week after appropriate practical instruction
100% checktests participation on schedule (exact date will notice minimal 1 week before). In case of checktests attendance in another date (not officially scheduled) its possible to obtain just 80% of conventional maximal amount of points. Each checktest its possible to repeat one time, in case of repeat checktest its 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, devided to:
T1 = max. 10 points
T2 = max. 10 points
Courseworks of practice instructions = max. 20 points
