Background

The energy transition is one of the defining challenges of our time. At the Karlsruhe Institute of Technology (KIT) we are not just observing this transformation, we are helping to build the infrastructure that will enable it.

The High-Power Grid Lab is being developed as one of the world’s most powerful testbeds for modern power systems. Its goal is to recreate complex grid conditions and test large-scale generation units and converter-based systems before they are deployed in the field. By identifying instabilities, interaction effects and failure scenarios in a controlled laboratory environment, we help ensure the reliability, stability, and safety of the power grids of tomorrow.

The heart of this facility is a cutting-edge SiC-based Modular Multilevel Converter (MMC) for medium-voltage applications, developed here at ETI. We are looking for bright and driven minds who want to become part of the larger mission by building the technological foundation for the next generation of sustainable power grids.

Your mission, should you choose to accept…

…is to help bridge the gap between theoretical concepts and high-power hardware reality. You will drive the development of the MMC cell architecture from a conceptual sketch to a functional high-performance prototype.

Your task begins with the core engineering of the cell where you design the power path including the selection of SiC semiconductors and capacitors along with a robust layout including the cooling system. Beyond that you will support the development of the nervous system of the cell by integrating measurement technology as well as gate drivers and error handling to ensure the survivability of the system even in demanding test scenarios. You will further contribute to the overall stack design of the entire MMC. This is the chance to leave a lasting footprint on the hardware that will power the future.
