Full Time

The Faculty of Information Technology and Electrical Engineering, at the Norwegian University of Science and Technology (NTNU) has a vacancy for a 100% position as Post Doctoral Researchers at Department of Electric Power Engineering (IEL)

Information about the department

Currently there are 9 professors and 8 associate professors at the department. In addition, there are 7 adjunct associate professors, 7 postdoctoral researchers and approx. 30 PhD students. Research activities are organized into two groups: Power systems and Power Technology.

Information about the position

The postdoctoral fellowship will be within a 20 MNOK research project entitled Reliability and ruggedness of high power high voltage power electronics (ReliPE), which is led by SINTEF Energy Research, with NTNU, Technische Universität Chemnitz, Statkraft, Électricité de France (EDF), GE Energy Power Conversion, and Mitsubishi Electric as project partners. The project is co-funded by The Research Council of Norway. The objective of the project is to strengthen the research on reliability of power electronics with main focus on the power semiconductors. The project aims to improve the cost-efficiency of high power converter systems through increased reliability, better understanding of failure mechanisms and tools for lifetime estimation. The postdoctoral fellowship will be granted for 2 years. Preferably, the starting date should be before November 2017.

Work description

It is expected that the postdoctoral fellow will have special emphasis on the assessment of methods for condition monitoring and lifetime prediction of components subjected to thermal stress, and their applicability for power semiconductors in his/her research. The successful candidate is also expected to contribute towards the development of new methods and standards for evaluating the reliability and lifetime of state-of-the-art Silicon IGBTs, and SiC power transistors. Based on the research outcomes, the postdoctoral researcher is also supposed to suggest design guidelines for high-power electronic converters by taking into consideration the findings of lifetime assessments. The candidate is expected to integrate with the project group as a whole, participate in and contribute to meetings and workshops, visit partners, and to contribute with ideas to their work, and to publish his/her research in highly-ranked scientific journals and conferences in collaboration with the other Universities and Industrial partners.

The postdoctoral fellow is furthermore expected to contribute to research training and education within applied power electronics, in companionship with Assoc. Prof. Dimosthenis Peftitsis at NTNU. This includes supervision of MSc and PhD students, lecturing in Prof. Peftitsis’ courses, and building up course material on design of power electronics, including aspects of semiconductor theory, reliability, and wide bandgap devices. It is also intended that the course material developed can be used in tutorials for industry and academia.


Applicants are strictly advised to address the following selection criteria:

  • A PhD degree in electrical engineering, with a thesis on power electronics, laboratory oriented, and preferably with emphasis on understanding of power semiconductors and reliability.
  • Scientific publications in top-ranked international scientific journals and conferences.
  • A high level of personal responsibility, initiative, and ability to work in a project team as well as independently.
  • Excellent analytical and communication skills, and the ability to communicate with both technical and administrative staff.
  • Excellent knowledge of written and spoken English.
  • The ability to teach and to guide MSc and PhD students in relevant topics.
  • Applicants are required to submit a one-page research proposal within the proposed research area.

Applicants currently enrolled in a PhD programme who expect to pursue the PhD degree before the date of appointment must forward documentation for the date of their final exam.

Appointments are made in accordance with the regulations in force regarding terms of employment for Post Doctoral Researchers issued by the Ministry of Education and Research, with relevant parts of the additional guidelines for appointment as a Post Doctoral researcher at NTNU. The person who is appointed must comply with the conditions that apply at any time to employees in the public sector. In addition, a contract will be signed regarding the period of employment.

Applicants who do not master a Scandinavian language must provide evidence of good English language skills, written and spoken.
