About the position

The Department of Electric Energy (IEL) at NTNU has a vacancy for a full-time 100% position as a Postdoctor Fellow within the field of degradation and breakdown in solid insulation systems under power electronics converter stresses.

During the last decades power electronic converters (PECs) have been introduced to control and transform electric power - and permeate society for numerous applications: zero-emission transport, renewable energy, and transmission. The PEC is a key technology to succeed with electrification of society and reach the climate goals set out by EU and UN.

PECs function as on/off switches, resulting in sharp-edged square wave voltages with high repetition rate. These sharp voltage flanks introduce different stress distributions internally in components and can induce or accelerate degradation and lead to premature breakdown. The SwoP (Impact of switched voltage waveforms on power components and grids) project will develop methods to measure, characterize and predict the increased stresses and accelerated degradation on power components exposed to fast PECs. Failure modes in electrical insulation will typically be partial discharges (PD), i.e., small local sparks that degrade insulation, and dielectric heating. PD measurements are feasible for quality assurance and factory assessment testing, as it identifies potential defects. However, there is no good documentation of correlation between PD level and life expectancy. Performing ageing studies along with diagnostics (e.g., PD and dielectric spectroscopy) gives insight in the relevance and information that could be derived from PD measurement. This should be combined with analysis of the mechanical and chemical material deterioration that leads to decreased electric withstand strength. To manufacture novel and lightweight insulation systems for electric propulsion and renewable energy generation, knowledge is thus needed on degradation mechanisms and suitable insulation materials under PEC stresses.

The work of this project will be associated with the project SwoP, which is a collaborative project involving NTNU, SINTEF Energy Research, University of Bologna (UniBo) and several national and international industry partners. The PhD Candidate will be employed at NTNU, and the workplace will be in Trondheim, in connection with this research project, with exchange to the University of Bologna for one year. The prospective candidate will be part of a project team that works in close collaboration with SINTEF, UniBo and industry partners.

The main supervisor will be Professor Kaveh Niayesh (NTNU) and the co-supervisors will be Prof. Andrea Cavallini (UniBo) and Dr. Espen Eberg (SINTEF Energy Research).

The main workplace will be in Trondheim.

Your immediate leader is Head of Department.

Duties of the position

Develop methods to measure, characterize and predict the increased stresses and accelerated degradation on power components exposed to fast PECs. Perform ageing studies and apply appropriate diagnostics methods.
The results of the project are expected to be published in high-quality scientific journals and presented at conferences and for research partners as well as for user partners within the project.

Required selection criteria

A Norwegian doctoral degree or corresponding foreign doctoral degree recognized as equivalent to a Norwegian PhD in Electric Power Engineering, Physics, Material Science, or Electrical Engineering. Applicants with a doctoral degree will be prioritized in the selection process.
Work and/or research experience in high voltage engineering and/or power electronics.
You must have very good English language skills, both written and spoken, corresponding minimum to the scale B2, preferably C1, in the Common European Framework of Reference for Languages (CEFR). Applicants from non-English speaking countries outside EU/EEA/Switzerland must provide preliminary documentation of English language proficiency, in terms of an approved test. One of the following test scores could be documented for this purpose:
- TOEFL internet-based test (iBT) — iBT enhanced score reporting is required. Your proficiency level for the overall test should correspond to a score in the range 101 - 79. Your proficiency level for each test section should correspond to at least ‘high intermediate’ level.
- IELTS — 7, with no section lower than 6.5 (only Academic IELTS test accepted)
- Cambridge English: Advanced (CAE) — 185 - 176.

Further assessment of both written and oral English language skills, and the ability to communicate fluently, will be conducted in the continued selection process and during any interviews for the shortlisted applicants.
