During the specialisation in Power Electronics and Drives (PED), you will study electric drive systems and learn about generators, power electronics, control systems, and integration of drive systems in transport and industry.
You will explore questions such as:
- How do we ensure production using the lowest possible energy consumption?
- Should future electrical vehicles be driven by a permanent magnet motor or an induction motor?
- Which kind of generator provides the highest efficiency in a given application?
- How does the drive system in a production process influence the production quality?
- How do we produce an electric motor with a high efficiency adapted to a production process?
The teaching in the programme takes place in an innovative, dynamic and challenging environment, through a combination of research-based courses, team-based project work, and a high degree of interaction with industrial partners and energy supply companies.
The companies take an active part in providing project proposals for the problem-oriented project work, guest lectures and visits to the companies.
In each semester (except for the last) you will spend half of your study time on courses and course work while the other half of your time will be spent doing a semester project. Each semester has an overall theme, and within this theme you conduct a semester project with your project group where you investigate and attempt to solve a relevant issue within your field of study.
The study programmes at AAU are based on problem based learning and project work, which gives you a unique opportunity to acquire new knowledge and competences at a high academic level in an independent manner. You get to apply theory to practice in your semester projects, which will better prepare you for your future career.
At the Department of Energy Technology, you will find well-equipped, modern test laboratories that enable you to conduct exciting laboratory experiments. These tests will verify the theoretical analysis that you apply during the project work.
The laboratories with advanced computer based measurement and control facilities allow you to perform realistic tests in the electrical and mechanical wind turbine area with possibilities for e.g. doing power system stability analysis and making power electronics converters.

This semester is common to the three electrical specialisations of the Master' programme in Energy Engineering: Electrical Power Systems and High Voltage Engineering (EPSH), Power Electronics and Drives (PED) and Wind Power Systems (WPS).
For students with a Bachelor of Science (BSc) degree from Aalborg University, the project work is 15 ECTS credits, whereas it is 10 ECTS credits (INTRO project) for students with a BSc degree from another university. The projects' technical topic is the same, but the students from another university have one extra course about Problem Based Learning (PBL) which is the primary teaching method used at Aalborg University.
The documentation of the project work is also different:
- Students with a BSc degree from Aalborg University should document the project work with a paper, a poster and a presentation at an internal conference (CES) accompanied by an appendix report, all in English
- Students with a BSc degree from another university should document the work with a project report written in English
In the project, you and your project group will analyse the dynamics of an electrical energy system or electrical apparatus. Your focus can be for example electrical power systems, electrical drive systems, wind power systems or a combination of these. In such systems, short circuits, starting procedures, control issues, etc., demand that the dynamic performance of the systems must be studied. You analyse and model the system you have chosen, and then you experiment in the laboratories to verify the system, a model of the system, or parts of the system.

In the second semester, your project will focus on modelling, analysis, simulation and control of an electric system which must include a power electronic converter and an electric machine. When you and your project group have chosen a system to study, you describe the system by using a dynamic model and analyse it in order to design a suitable digital controller for the whole or parts of the system. Also, you study the dynamic interaction between the different parts of the system. All or parts of the system will be built and tested in the laboratory, including real-time implementation of controllers in e.g. digital signal processors, to provide verification of the models used.
- Control of Electrical Drive Systems and Converters (5 ECTS)
- Advanced Power Electronics and Applications (5 ECTS)
- Optimisation Theory and Reliability (5 ECTS)
- Control of Power Electronic Systems (15 ECTS)
examples of PROJECT topics
- Wide-bandwidth current control of PWM inverter-fed induction motor drive with LC filter
- Sensorless control of a brushless motor drive system
- Energy efficient control of permanent-magnet motor for electric vehicle
- Control of wide-bandwidth actuator for application in robotics
During the third semester, you have different options to earn the required 30 ECTS credits:
- You can do an internship in Denmark or abroad, where you take part in the day-to-day operations in the business. During the internship, you will write a project about one or more of your tasks during the process
- You can do a semester at another educational institution abroad or in Denmark
- You can do a regular semester at AAU with courses and project work
- You can begin your Master’s thesis, so your work is spread out over both your 3rd and 4th semester
Aalborg University has collaboration agreements with universities around the world, and the programme’s research environment has a wide range of internship contacts.
Find out more about studying abroad and internships here.
If you opt to stay at AAU, you will choose elective courses that give you 10 ECTS credits and you will work on a project that is based on an electrical power system or a high voltage system. You will set up and model an optimisation, control or diagnostic system, and the system must be implemented and verified experimentally in the laboratories.
To practice scientific communication skills, the project’s result, or parts of it, must be published in an article written in English. This article is presented at an internal seminar (CES).
- Elective course (5 ECTS) *
- Elective course (5 ECTS) *
- Advanced project in Power Electronics and Drives (20 ECTS)
* The elective courses can be seen at this website and may vary from year to year, depending on the number of students in the various specialisations, the on-going projects and the research performed at the Department of Energy Technology. Further, courses from other universities might be used as elective courses.
In the fourth semester, you write your Master’s thesis where you draw on all the knowledge, experience and skills you have acquired during your studies. Depending on your choice of topic, the thesis can take the form of developmental work, further development, or actual research.
