NTNU - knowledge for a better world

The Norwegian University of Science and Technology (NTNU) creates knowledge for a better world and solutions that can change everyday life.


Faculty of Information Technology and Electrical Engineering (IE)

Department of Electric Power Engineering (IEL)

PhD position at the Department of Electric Power Engineering within "Power Electronics for MVDC Circuit Breakers"

The Faculty of Information Technology and Electrical Engineering (IE), http://www.ntnu.edu/ie at the Norwegian University of Science and Technology (NTNU) has a vacancy for a 100% position (3 years) as a Research fellow at the Department of Electric Power Engineering (IEL) http://www.ntnu.edu/elkraft.

 

Information about the Department of Electric Power Engineering

Currently there are 11 professors and 6 associate professors at the department. In addition, there are 4 adjunct professors, 7 postdoctoral researchers, approx. 30 PhD students. Research activities are organized into two groups: Power systems and Power Technology.

 

The department has a wide range of teaching responsibilities, ranging from fundamental education in electric power engineering for other engineering students, Master’s programs in Energy and Environment, International MSc programs within Electric Power Engineering and Wind Energy, as well as PhD education and continuing education.

 

Work description

Medium voltage DC (MVDC) distribution grids (either point-to-point or multi-terminal) have started gaining attention due to their advantageous performance compared to the conventional MV AC counterparts (lower losses, flexible power control and elimination of reactive power compensation, etc.). DC distribution grids on vessels and O&G offshore platforms, DC collector grids for offshore wind generation and large-scale energy storage integration count as very promising application areas of MVDC. A design barrier for MVDC systems, however, is associated with short-circuit fault handling. In particular, under a short-circuit fault condition in MVDC systems the absence of natural “zero-crossing” in the direct fault current makes the conventional AC breakers unable to clear direct fault currents. Two MVDC breaker concepts exists: the hybrid MVDC breaker which combines a conventional AC breaker with power electronic circuits and the purely solid-state MVDC breaker that only employs power semiconductors. Fault clearing times, maximum allowed overvoltage across the breaker and fast residual energy dissipation are listed among the crucial design challenges of MVDC breakers.

Currently, there is one vacant PhD position available at NTNU within the field of “Power electronics for MVDC circuit breakers”.

 

The successful PhD candidate is expected to design novel power electronic solutions for the future MVDC circuit breakers. In particular, the PhD candidate will investigate the power semiconductor requirements and performance including investigations of novel semiconductor materials (e.g. SiC), their control circuits and auxiliary systems. The PhD project will be implemented using theoretical investigations (simulations and numerical calculations) and advanced experimental validations of various MVDC breaker concepts under real operating conditions.

 

Qualifications

Applicants must hold a M.Sc. degree (or equivalent) within electrical engineering with a specialization in Power Electronics. Applicants with a laboratory experience on power electronics (design of power electronic converters prototypes, programming of FPGAs and DSPs etc.) will be preferred. Scientific publications in international journals and conferences are merited.

 

Applicants are required to submit a one-page research proposal within the proposed research area.

 

The ability to work in team and good communication skills will be emphasized in the employment process.

 

The PhD position is expected to start in summer 2017.

 

Applicants who do not master a Scandinavian language must provide evidence of good English language skills, written and spoken. The following tests can be used as such documentation: TOEFL, IELTS and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English.

 

(CPE). Minimum scores are:

TOEFL: 600 (paper-based test), 92 (Internet-based test)

IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)

CAE/CPE: grade B or A.

 

Appointments are made in accordance with the regulations in force regarding terms of employment for PhD candidates issued by the Ministry of Education and Research, with relevant parts of the additional guidelines for appointment as a PhD candidate at NTNU. Applicants must undertake to participate in an organized PhD programme of study during their period of employment. 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 must be qualified for admission as PhD students at NTNU. See https://www.ntnu.edu/ie/research/phd for information about PhD studies at NTNU.

 

High motivation and good analytical and communication skills will be emphasized in the employment process.

 

We can offer

  • an informal and friendly workplace with dedicated colleagues

  • academic challenges

  • attractive schemes for home loans, insurance and pensions in the Norwegian Public service Pension Fund
