PhD candidate for developing physics-based loss models of advanced magnetic devices for future highly efficient drive 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 mobility. 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. For a new research project on advanced high efficiency magnetic devices, we are looking for a: PhD candidate (100%) for developing physics-based loss models of advanced magnetic devices for future highly efficient drive and converter systems
We are lookingfor outstanding, highly motivated individuals interested in pursuing a PhD in the multidisciplinary and important research area of modelling and optimisation of magnetic components and electric machines. Highly efficient as well as compact transformers and chokes are critical elements in most power electronic systems, because these components drastically influence the overall efficiency and power density of converters. Similarly, in electric drive systems the overall efficiency and power density are significantly affected by the iron and winding losses in the machine. In order to pace with the rapid development of semiconductors (e.g. wide bandgap SiC MOSFETs/GaN HEMTs), advanced concepts for magnetic devices and in particular comprehensive models of the core losses should be developed by you. These models should be integrated in a computationally efficient way into optimisation procedures for power electronic converters and are essential for achieving outstanding system efficiencies and power densities as well as for gaining a competitive edge. For verifying the new concepts and the developed models, you will design and build novel core loss characterisation systems and evaluate the loss characteristics in detail by measurements. This project is part of an ongoing wider modelling framework development at HPE and also offers the opportunity to collaborate with other PhD candidates. A recent PhD thesis at HPE has also developed some physical loss models for ferrite core devices, which can be used as a basis for the project.
The candidate must have a diploma/M.Sc. degree in electrical engineering and/or physics with excellent grades, fundamental knowledge of power electronic converter systems, good communication skills, fluency in English and the willingness to fully commit yourself as part of an international team. In addition, you should be interested in the comprehensive modelling of power semiconductor devices as well as the function and optimal design of power electronic.
