Welcome to Modelling and Control of Voltage Source Converters and AC Drives


Voltage Source Converters (VSCs) have commonly been used with renewable power sources, flexible ac and dc power transmission or distribution systems, energy-efficient power loads, and transportation electrification. As their ever increasing penetration level in electrical grids, dynamic characterizations of VSCs are playing a critical role in building a stable and resilient power-electronic-based power system.

This course thus devotes to cover the fundamentals and state-of-the-art of modeling and control topics for VSCs in both grid-connected applications and variable speed drives.

1. Fundamentals of vector control and current control of VSCs

2. Dynamic models of induction motors and permanent-magnet synchronous motors

3. Fundamentals of sensor-less control of ac drives

4. Impedance-based modeling and stability analysis of VSCs

5. Advanced modeling techniques of VSCs for harmonic interaction and stability analysis

6. Active stabilizing techniques for VSC-fed systems


Prior knowledge of power electronics basics, pulse width modulation, and three-phase systems is preferred.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 5,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
