PhD candidate for developing multi-physics models of high-power medium frequency transformers

ETH Zurich seeks a PhD candidate to develop multi-physics models for high-power medium-frequency transformers, focusing on optimization and prototype verification in an international research team.

This position is embedded within a broader modeling framework development project at the High Power Electronics (HPE) group. The successful candidate will pursue a doctoral degree centered on the modeling and optimization of high-power, medium-frequency transformers. The role encourages collaboration with other PhD researchers working on related modeling challenges.

Responsibilities

• Create multi-physics models that account for high-frequency losses, thermal distribution, resonances, and electrical insulation behavior.
• Optimize the geometry of cores and windings, design advanced cooling strategies, and engineer connections for high-current windings.
• Utilize developed models to identify technological limitations regarding the transferable power and efficiency of medium-frequency transformers.
• Integrate these models into optimization procedures for power electronic converter systems with a focus on computational efficiency.
• Design and construct medium-frequency transformer prototypes, including associated converter systems, to verify performance under realistic operating conditions.

Requirements

• Hold a diploma or Master of Science degree in electrical engineering with excellent academic grades.
• Demonstrate fundamental knowledge of power electronic converter systems.
• Possess strong communication skills.
• Be fluent in English.
• Be prepared to fully commit to the role within an international team environment.

Nice to have

• Interest in the detailed modeling and design of magnetic components and the optimization of power electronic systems.
