PhD candidate for developing multi-physics models of high-power medium frequency transformers ETH Zürich in Switzerland

The Laboratory for High Power Electronic Systems (HPE) at the Department of Information Technology and Electrical Engineering, ETH Zürich, is seeking a PhD candidate to develop advanced multi-physics models of high-power medium frequency transformers (MFTs). The research is part of a new project focused on Solid-State-Transformers (SSTs) for future data centres, where efficient power transfer and high system voltages are critical for AI and high-performance computing applications. The position offers the opportunity to work at one of the world's leading technical universities, renowned for its excellence in education, research, and societal impact.

As a PhD candidate, you will develop multi-physics models that capture high-frequency losses, cooling and temperature distribution, resonances due to parasitic capacitances, and electrical insulation in MFTs. You will optimise core and winding geometry, design advanced cooling concepts, and create solutions for efficient high-current connections. The models and concepts you develop will be integrated into optimisation procedures for power electronic converter systems, aiming for outstanding system efficiencies and power densities. You will also design and build MFT prototypes and converter systems to validate your models under realistic conditions.

The HPE laboratory is internationally recognised for its research on power electronic converter systems, including applications in energy distribution, traction/electric vehicles, medical systems, and accelerators. The modelling work is part of a broader framework, offering collaboration opportunities with other PhD candidates. ETH Zürich values diversity, sustainability, and an inclusive culture, actively promoting equality of opportunity and working towards a climate-neutral future.

Applicants must have a diploma or M.Sc. degree in electrical engineering with excellent grades, fundamental knowledge of power electronic converter systems, good communication skills, and fluency in English. Commitment to teamwork and interest in detailed modelling and design of magnetic components are essential. The position is full-time and offers a competitive salary, excellent benefits, and access to outstanding research and laboratory facilities. Additional benefits include public transport season tickets, car sharing, childcare, and attractive pension plans.

To apply, submit your application online via the ETH Zurich portal, including a comprehensive CV, transcripts, thesis/publications, and references. Applications via email or postal services will not be considered. For further information, contact Prof. Dr. Jürgen Biela at [email protected] (no applications).

ETH Zürich is located in Zurich, Switzerland, and is home to over 30,000 people from more than 120 countries. The university fosters independent thinking and excellence, working together to address global challenges in science and technology.
