• Development of a Modular Multilevel Converter Demonstrator with EtherCAT Communication

  Fey, J.-H., Hinrichsen, F., Carstens, G., & Mallwitz, R. (2019). Development of a Modular Multilevel Converter Demonstrator with EtherCAT Communication. In 2019 IEEE 13th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG) (S. 1–6). Sonderborg, Denmark. http://doi.org/10.1109/CPE.2019.8862424

  Abstract

  The Modular Multilevel Converter (MMC) is a proven topology in HVDC, but it is also a suitable solution for medium voltage applications such as wind turbines. To increase the modularity and the scalability of this topology for medium voltage applications, a real-time communication bus between the submodules and the central control unit is implemented as an efficient way of control. This real-time communication is realized using EtherCAT communication. To verify the advantages of this control strategy a 3-kV 350-kVA demonstrator of a medium voltage MMC topology with EtherCAT communication is constructed and set up. The description and the analysis of this demonstrator with focus on the EtherCAT communication are presented in this paper. The communication path, the synchronization and the control including the modulation method are discussed, investigated and validated within this paper.

• Potential of AR for the Analysis and Training of Spatial Skills: A Case Study

  Dohse, F., Nicolaisen, V., Wetzel, S., & Bertel, S. (2019). Potential of AR for the Analysis and Training of Spatial Skills: A Case Study. In Proceedings of Mensch Und Computer 2019 (S. 537–541). New York, NY, USA: Association for Computing Machinery. http://doi.org/10.1145/3340764.3344453

  Good spatial skills are of particular importance in STEM domains. For the training of spatial skills, smartphones provide a promising platform because of their high dissemination. Additionally, new frameworks make it easy to develop and use augmented reality (AR) contents. To examine the potential of AR for the training of spatial skills, we developed a prototype of a smartphone app for the solving of cross section tasks.The prototype was tested in a user study with 32 university students. It was compared against a second prototype with a classical Arcball interaction. For both prototypes, success rates were equally high. However, 3D-objects could be rotated faster using the AR-app. For the AR-app, participants reported higher scores regarding innovation and motivation but also for physical demands. This is especially interesting because motor activity and spatial skills are highly connected. Therefore, the physical approach might be promising for the development of spatial skill training apps which might lead to good long-term training results.
