The students gain knowledge on the basic principles and components of power electronics and about the converter circuits, both for self-commutated as well as for grid-commutated applications. They get familiar with special control structures for power electronics using the example of a current control. Thus they are able to select from the variety of complex electronic power circuits the most favorable for a specific application and to select the correct mathematical description. Since power electronics are an indispensable part of daily life today, the prerequisites for use in many different occupational fields are being created. The acquired basic knowledge also enables successful and targeted communication with experts in the field of power electronics.
Power electronics enable the specific application of electric energy at a very high degree of efficiency. It contributes to improve the operating properties considerably at concurrently reduced energy consumption. Traffic systems, industry plants and current supply systems of, e.g., computer make use of this so that power electronics are one of the most important future technologies. At first, the lecture explains the basic principles of power electronics, followed by a detailed description of the most important power-electronic components and their properties. Design and function of essential self-commutated and grid-commutated power converter circuits are explained in detail. Examples for such power converter circuits are three-phase bridge connections as rectifier circuits and boost resp. step-down converters for the adjustment of DC voltages. Power-electronic units itself are used as control elements, so that the control is of particular relevance and must be tailored to the power-electronic properties. This is explained in the lecture by a current control example.
- Proficiency in the power electronics-related part of the lecture 'Fundamentals of Electrical Engineering III - Power Engineering'
- Basic knowledge of electronic components, e.g. from the lecture 'Electronic Components'.
