Doctoral Position in solid-state transformer development, with a focus on high-power medium-frequency transformers in Zürich

• Comprehensive CV
• 100%, Zurich, fixed-term

The Laboratory for High Power Electronic Systems (HPE) at the Department of Information Technology and Electrical Engineering of ETH Zurich conducts internationally leading research on power electronic converter systems, which are required, for example, in future energy distribution systems for the integration of renewable energy sources or in traction applications/electric vehicles.

Another research focus is on solid-state pulse modulators for medical applications (computer tomography/cancer treatment) and accelerators (CERN).

For the design and optimisation of the various power electronic systems, we develop advanced multi-physics models/digital twins/virtual prototypes at the component and system level.

For a new research project on Solid-State-Transformers for future PV and energy storage systems, we are looking for a: Doctoral Position for developing solid state transformers with the focus on high-power medium frequency transformers.

Job Description
