Each module contains 3 ECTS. You choose a total of 10 modules/30 ECTS in the following module categories:
- 12-15 ECTS in technical scientific modules (TSM)
TSM modules teach profile-specific specialist skills and supplement the decentralised specialisation modules.
- 9-12 ECTS in fundamental theoretical principles modules (FTP)
FTP modules deal with theoretical fundamentals such as higher mathematics, physics, information theory, chemistry, etc. They will teach more detailed, abstract scientific knowledge and help you to bridge the gap between abstraction and application that is so important for innovation.
- 6-9 ECTS in context modules (CM)
CM modules will impart additional skills in areas such as technology management, business administration, communication, project management, patent law, contract law, etc.

Building upon the students' fundamental knowledge in power electronics, this module covers current topics in the field of power electronics in greater depth. In the first part, the focus is on modern switched mode power conversion topologies, small signal modelling, control methods and the magnetic components. The second part looks into topologies, modulation schemes and control techniques for medium and high-power converters. One application discussed in greater depth is their application in power grids.
To attend the module, a good fundamental knowledge in electrical engineering is essential. In addition, a sound basis in power electronics and control technique is needed.
- Power electronics: Characteristics, driving and application of power diodes, thyristors, MOS- field effect transistors, IGBT, as well as GTO-thyristors, are known.
- The basic power electronics circuits, with and without galvanic isolation, are known and understood. E.g. boost and buck converter, flyback and forward converter, one- and three-phase self-commutated bridges with semiconductors having turn-off capability, line-commutated rectifiers.
- System description with transfer function can be derived and represented in a Bode diagram. Additionally, a basic knowledge of descriptions in state space is useful.
PI- controller design with help of the Bode diagram (or other methods) can be carried out.
The students are taught modelling methods, structure and control of power electronics circuits based on selected practical and realistic examples.
