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

Doctoral research on modelling and optimisation of high-power Solid-State Transformers (SSTs), focusing on Medium-Frequency Transformers (MFTs). Investigation of high-frequency and high-voltage MFTs for PV systems and medium-voltage grids. Integration of battery storage systems and control of dynamic power flow between batteries and the grid. Development of multiphysics models for losses, temperature, cooling, resonances and electrical insulation. Optimisation of core, windings and cooling for improved efficiency, power density and power transfer. Development and optimisation of SST systems and power electronic converters. Integration of models into computationally efficient optimisation procedures and collaboration with other Doctoral Position. Design, construction and experimental validation of MFT prototypes and converter systems.

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.
