On May 8, 2025, 35 students from Prof. Marc Hiller's master's course “Power Electronics” attended the Students Day at the PCIM Expo & Conference in Nuremberg. PCIM is the leading international trade fair for power electronics, intelligent drive technology, renewable energy, and energy management. This makes the PCIM Expo & Conference the most important global industry gathering and the home of power electronics. During a tour of the expo, the students had the opportunity to learn about the latest developments in the field of power electronics firsthand. In addition, new technologies were presented as part of a wide range of presentations.

The Institute of Electrical Engineering (ETI) would like to thank the European Center for Power Electronics (ECPE) based in Nuremberg for the excellent organization of the Student Day and the KIT Faculty of Electrical Engineering and Information Technology for covering the travel expenses

The ETI congratulates Mr. Benedikt Jux on passing his doctoral examination. The title of his dissertation is "Semi-Analytical Multi-Physics Design of High-Speed Permanent Magnet Synchronous Machines for Hydrogen Fuel Cell Air Compressors." The examination date was June 27, 2025.

On 3 April 2025, the annual Girls' Day took place at KIT. As part of one of 78 (!) workshops offered at KIT, schoolgirls in grades 5-7 at the Electrotechnical Institute (ETI), for example, had the opportunity to build their own electric motor. All participants mastered the task with great success and joy, so that in the end everything ran “smoothly”. Many thanks to all the helpers who made this great day at KIT possible.

Kickoff has been given for the High Power Grid Lab (HPGL). By 2030, a globally unique test environment is to be created at KIT in which the system behavior of new grid technologies can be researched under realistic conditions. Even in the construction phase, the HPGL will form an international transfer hub for knowledge and technology in practical applications.

The ETI presented a multilevel converter with integrated battery modules at the Hannover Messe. The approach of using second-life batteries in the efficient converter met with a great response from trade visitors and politicians.

On the IEEE 9th Southern Power Electronics Conference (SPEC) 2024 in Brisbane (Australia) our Paper "Recursive Moving Lean Instant Slope Constant Estimator for Online Measurement of Derivative and Absolute Value of Oversampled Signals" received the Best Paper Award. Contragulations!

On the ECCE Europe 2024 our Paper "Modelling and Characterization of Power Semiconductors in the Frequency Domain" recerived the Best Paper Award. Congratulations!

At the PCIM in Nuremberg, our external PhD student Bhaskar Chatterjee received the Best Paper Award for his paper "A Partial Load Three-Phase Triangular Current Mode Modulation Concept with an Optimized Filter Inductor for High Efficiency Traction Drives". Congratulations!

The ETI uses a high-performance, modular and fully customizable real-time signal processing platform for the control and regulation of all types of applications in the field of power electronics and electric drives - the "ETI SoC system". The term "SoC" stands for "System-on-Chip", as both a floating point signal processor (DSP) for sequential code and a freely programmable hardware for fast, parallel computing operations (FPGA) are integrated on one chip.

Das ETI gratuliert Herrn Felix Hoffmann zur bestandenen Doktorprüfung. Der Titel seiner Dissertation lautet „Thermische Modellierung permanentmagneterregter Synchronmaschinen mit wellenseitiger Öl-Sprühkühlung“. Das Prüfungsdatum war am 24.04.2024. 

The Electrotechnical Institute celebrated its 125th anniversary and the retirement of Prof. Braun on 7 July 2023. The two-year delay due to the pandemic did not inhibit the celebratory mood. The 170 invited guests enjoyed various technical and historical lectures. One of the highlights was the joint lecture by the current institute management together with Georg Schuisky, who had traveled from Sweden for the occasion. In the lecture, not only was the history of the institute presented, but it was also brought to life through the eyewitness account of Schuisky's father. Another special guest was the grandniece of the Institute's founder Prof. Arnold. Prof. Braun closed the official part of the celebration with his final speech and drew a varied summary of his management of the institute.

In the research project Solarpark 2.0, KIT is working together with partners from science and industry to reduce these losses. Innovative circuits, novel power electronics and KI-supported optimization are intended to increase the yield and service life of plants and reduce operating costs.

In December 2022, the ceremonial handover of two design panels for Dynabobau took place. Prof. Hiller received the boards from Willem de Jong on behalf of the institute's management.
