PhD candidate for developing, modelling and optimising new concepts for ultra-fast, high-power pulse Generators



The Laboratory for High Power Electronic Systems (HPE) at the Department of Information Technology and Electrical Engineering performs international leading research on power electronic converter systems required for example in future energy distribution systems for integrating renewable energy sources or in traction applications/electric mobility. A further research focus is on solid state pulse modulators for medical applications (computer tomography/cancer treatment) and accelerators (e.g. CERN). For a new research project in the area of advanced pulsed power, we are recruiting a PhD candidate (100%) for developing, modelling and optimising new concepts for ultra-fast, high-power pulse generators.

Job description
We are looking for outstanding, highly motivated individuals interested in pursuing PhD research in the interdisciplinary area of pulse generator (modulator) systems. The research topic focusses on the development of new concepts for pulsed power modulators, which should generate pulses with a very fast pulse rise times (<100ns), with a pulse amplitude in the range of tens of kilovolt, and with a high pulsed output power of more than 100MW. With the modulator system, new drilling concepts for cost efficient drilling of very deep holes required for enabling a broad application of geothermal energy for base load energy provision are investigated. Besides the development of the basic modulator concept, the PhD position involves also the detailed modelling and optimisation of the modulator system. For verifying the concept and the models, laboratory scale test systems are built and operated in our medium voltage laboratory. After a successful test, a full-scale prototype system could be built in collaboration with an industry partner.

In our lab, you can expect a challenging and scientifically highly exciting full-time position in a dynamic, international team at one of the world-wide leading technical universities. Furthermore, we strongly support participation at international conferences and offer a competitive salary, excellent benefits as well as outstanding research and laboratory facilities for your experiments.

Your profile
You 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 pulsed power systems and should be willing to make yourself familiar with basics of plasma physics, since the load of the modulator system is an arc.

ETH Zurich
