Students understand how to apply self-commutated converters in practical applications. They know the available topologies, their properties and the power-electronic elements which can be used to construct such converters. The students are able to select those elements suited best for a target application, also regarding the associated effort. They choose and dimension the needed input and output filters. Advantages and disadvantages of various converters operating at the grid are known, special types of current control for such converters understood. Out of many technical options, using interdisciplinary competences, the best solution – taking into account various partially contrary demands – is constructed.


This lecture focuses self-commutated converters and their application to the control of electric power. As a basis an overview of typical topologies of self-commutated converters is give. The associated power-electronic element and their properties are introduced. Switching losses and their reduction are discussed in detail. ** Harmonics** resulting from switching of power semiconductors have to be limited. Advantages resulting from the use of self-commutated converters in comparison to line-commutated converters are analysed. However, such concepts require more effort and are more expensive – which is one of the relevant selection criteria in practical applications. Relevant concepts and their respective properties are discussed. Control, specially current control , closes the lecture. In the context of control the switching of power electronics and its effect on the control chain is discussed . Special control structures which incorporate this switching behaviour directly are presented.
