PhD candidate for developing multi-physics models of …, Zürich (Kreis 11)

PhD candidate for developing multi-physics models of high‑power medium frequency transformers 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. For a new research project on solid‑state transformers for future data centres, we are looking for a

PhD candidate (100%) for developing multi‑physics models of high‑power medium frequency transformers .

We are looking for highly motivated individuals with an outstanding academic background who are interested in pursuing a PhD in the important and multidisciplinary research area of modelling and optimising high‑power, medium‑frequency transformers (MFTs). Compact, highly efficient transformers that operate at kilohertz frequencies are key components of high‑power DC‑DC converters, which are the core component of solid‑state transformers (SSTs).

For pushing the efficiency and power density limits of these SSTs you will develop multi‑physics models of transformers which describe not only the high‑frequency losses in the winding and the core, but also the cooling temperature distribution, resonances in the winding due to parasitic capacitances, and electrical insulation. You will also work on optimising the core and windinggeometry, developing advanced cooling concepts for the windings and core, and designing solutions for efficiently connecting the high‑current windings. Using the models and concepts developed, you will identify technological barriers to the transferable power and efficiency of MFTs.

The developed models should be integrated into optimisation procedures for power electronic converter systems in a computationally efficient way. This is essential for achieving outstanding system efficiencies and power densities. The models are also part of an ongoing, wider modelling framework development project at HPE, offering the opportunity to collaborate with other PhD candidates on different modelling aspects.

For verifying the new concepts and developed models, you will design and build MFT prototypes, including converter systems, to operate the MFTs under realistic conditions.
