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. These systems are essential for future energy distribution frameworks, especially for the integration of renewable energy sources and in traction applications such as electric vehicles. Another key focus area includes solid-state pulse modulators for medical applications, like computer tomography and cancer treatment, as well as accelerator technologies (CERN). For a new research initiative focusing on Solid-State Transformers intended for future data centers, we are seeking a:
We are inviting highly motivated individuals with an outstanding academic background to consider pursuing a PhD in the vital and multidisciplinary sector of modeling and optimizing high-power, medium-frequency transformers (MFTs). Compact and highly efficient transformers, operating at kilohertz frequencies, serve as integral components of high-power DC-DC converters fundamental to solid-state transformers (SSTs). These SSTs are critical for future AI data centers, where power demands can escalate to several hundred kilowatts or even megawatts per computer rack.
To facilitate efficient energy transfer from the grid to CPUs and GPUs, higher system voltages must be employed in data centers and computer racks. Advanced power electronic converter systems based on SSTs are essential to manage the highly dynamic power flow.
Your role will involve developing multi-physics models of transformers that capture not only high-frequency losses in windings and cores but also aspects like cooling and temperature distribution, resonance caused by parasitic capacitances, and electrical insulation. You will optimize core and winding geometry, create innovative cooling concepts, and design solutions for effectively connecting high-current windings. These models will be pivotal in identifying technological barriers to transferable power and efficiency in MFTs.
Furthermore, you will integrate the developed models into optimization procedures for power electronic systems, a vital step to achieving top-notch system efficiencies and power densities. This initiative is part of a broader framework development project at HPE, offering a collaborative environment with fellow PhD candidates focused on various modeling aspects.
To verify your innovative concepts and models, you will design and construct MFT prototypes, including converter systems to test the transformers under realistic operating conditions.
The successful candidate will work at ETH Zurich, a world-renowned technical university that engages in cutting-edge research and promotes professional growth.
