Course content

The course focuses on presenting the fundamental concepts on conversion, control and monitoring of electric energy using power semiconductor devices.

Methods for analyzing power electronic converters suitable for AC/DC, DC/DC and DC/AC electrical energy conversions including resonance converters are presented.

Additionally, principles for designing power electronic converters, including their power semiconductors and passive elements are established. Computer-aided analysis and simulations of the electrical and thermal performance of power electronic converters is also among the course objectives.

The application of power electronic converters in the fields of sustainable energy technologies such as wind energy, solar power, wave energy, and fuel cells are described. Furthermore, industrial applications like SMPSs, UPSs and induction heating, as well as, application of power electronics for transmission, distribution and control in the future power system, including Smart Grid, is described.

Learning outcome

After completing the course, the student will
- have an in-depth understanding of the theory of electrical energy conversion using power electronic systems that perform AC/DC, DC/DC or DC/AC conversion, including applications within renewable energy, energy saving and industrial applications.
- understand operating principles and modulation strategies for single-phase and three phase diode rectifiers, thyristor-based converters, as well as, switch-mode DC/DC power electronic converters and DC/AC inverters.
- understand advanced modeling and control of power electronic converters.
- be able to identify the most important design parameters and to recognize the impact of operating parameters on the planning and use of power electronic converters in the existing and future electric power grid infrastructure, and in industrial installations.

After conclusion of the course, the student will be able to:
- recognize, define, and analyze power electronic converters that perform AC/DC, DC/DC and DC/AC electrical energy conversions.
- model and simulate the electrical, thermal and electromagnetic performance of power electronic systems using advanced electric circuits and finite-element simulation tools.
- design power electronic converters exhibiting high-performance operation with argument criteria.
- analyse the operating principles and modulation strategies for single-phase and three phase diode rectifiers, thyristor-based converters, as well as, switch-mode DC/DC power electronic converters and DC/AC inverters.
- plan and operate the use of power electronic converters in the present and future electric grid and industrial installations.
- use instruments and equipment in the laboratory.

General competence:
After completing the course, the candidate has increased:
- skills in cooperation and interdisciplinary collaboration
- ability to communicate effectively to professionals and non-specialists alike through reports and presentations
- ability to contribute to innovation and innovation processes

Learning methods and activities

Lectures. Exercises, out of which 4 count in the final grading if they have positive effect. Compulsory laboratory experiments. Compulsory project work that also counts in the final grading. The course is given in English.

Compulsory assignments

  • Laboratoriearbeid med rapport
  • Prosjektarbeid med rapport og presentasjon

Further on evaluation

The final evaluation will be based on a written examination (counting 55%), project work with presentation (counting 25%) and exercises (counting 20%) based on % fulfillment. Final grading will be from A to F. The exercises consists of 4 separate exercises counting 5% each. The exercises are not compulsory, and do only count if they have a positive effect on the total assessment. In cases where the exercises are not submitted or have negative effect, the final grading will be based on written examination (counting 75%) and project with presentation (counting 25%).
If there is a re-sit examination, the examination form may change from written to oral.
In the case that the student receives an F/Fail as a final grade after both ordinary and re-sit exam, then the student must retake the course in its entirety.
Permitted examination aids, support material code D: No printed or hand-written support material is allowed. A specific basic calculator is allowed. In addition, calculator Casio fx-991EX is allowed.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
