Synopsis:

The aim of the study is to introduce students to the principles and functions of latest topologies of power semiconductor electric energy converters, taking into account the scope of their PhD thesis.

Content of the subject is the optimization of the power conversion parameters in power semiconductor converter systems. The subject is oriented mainly on new trends in the use of new principles, topologies, functions and possibilities of application of power semiconductor converters realized on the basis of modern power semiconductor devices and using increasingly powerful control microcomputers. The topics are focused on pulse width modulation methods for voltage and current control, modes of operation of converters with unity power factor, active control of the current curve and the voltage curve, as well as the overall quality of electric energy transmission. The problems of analysis and synthesis of matrix converters, multi-level converters, resonant converters as well as problems related to their practical use are also solved.
