In July 2025, Mr. Armin Huber celebrated his 50th work anniversary at ETI. The institute management and all colleagues thank Mr. Huber for his many years of loyalty and his tireless dedication. We warmly congratulate him on this special anniversary and wish him continued all the best, health, and joy in his work.

Sophia Beck has been awarded the Erna Scheffler Prize 2025. This prize recognizes her outstanding master's thesis on “Assessment of Methods for the Permanent Magnet Flux Estimation during Machine Operation.” We congratulate her on this special award and are delighted that she has received this well-deserved recognition.

On 17 May, the KIT Open Day was held for the first time as a science festival for the public at the same time as the Campus Day, where prospective students could find out about studying at KIT.
The EIT took part in the knowledge rally for children and guided tours through the institute's laboratories. Visitors were able to experience electrical engineering live during exciting experiments in the lecture hall and help with the production of electronic boards in the assembly room. Those who like racing could take an electric car for a spin on the driving simulator.

On June 26, 2025, Prof. Dr.-Ing. Bruno Burger was farewell as a lecturer at ETI. Since 2000, he had been giving lectures in the field of solar cells and since 2004 the lecture "Power Electronics for Photovoltaics and Wind Energy." Bruno Burger began his studies at the then University of Karlsruhe in 1985, completed his diploma in 1991, and successfully finished his doctorate at ETI in 1997. He was then significantly involved in the development of the Fraunhofer ISE in Freiburg. With the best wishes for the future, Prof. Hiller and Prof. Doppelbauer, along with the students and staff of ETI, bid farewell to Bruno Burger. They presented him with a model of a motor made in the ETI workshop as a keepsake of the wonderful time at ETI. Mr. Burger emphasizes at his farewell that it has always been a great joy for him to work with the students and to inspire them for renewable energies.

We wish him only the best for his well-deserved retirement and will continue to eagerly follow the Energy-Charts.

Every year, The smarter E Europe exhibition—Europe’s largest alliance of energy exhibitions—recognizes pioneering innovations that shape the future of the energy world. At this year’s edition, we are proud to celebrate “The Smarter E Outstanding project award 2025” granted to project “BiFlow”. The project realizes a hybrid energy storage concept in real-world and demonstrates an innovative heat sector coupling solution.

This year's Faculty Teaching Award goes to Dr. Andreas Liske from the Electrical Engineering Institute (ETI). Over the years, Andreas Liske has delivered and developed courses on control of power electronic systems, real-time systems for electrical drives, converter control technology, and circuit technology in industrial electronics with outstanding expertise. His teaching style is characterized by highly intuitive explanations, well-chosen illustrations and drawings, and a reasonable pace. Furthermore, all lectures are offered in an excellent hybrid format, with both live streaming and recording for follow-up. Congratulations!

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.
