Welcome to Modular Multilevel Converters (MMC)


MMC has been established as the technology of choice for HVDC, large utility scale STATCOM and Multil-MW drives. This course will present the fundamentals, dynamics, modelling and simulation, modulation, control and balancing as well as control under unbalanced grid. Control and operation challenges for MMC application in HVDC, STATCOM and DRIVES will be also presented. The course structure is: Day 1: MMC fundamentals, topologies and design Day 2: Modulation techniques (PSPWM, NLC+Sorting, Model Predictive Sorting) Day 3: Control and balancing Day 4 Applications of MMC (HVDC, STATCOM, DRIVES) Around 40 % of the time will be spent in exercises using PLECS and Simulink models. A demonstration of several MMC applications will be organized in the state of the art MMC Laboratory

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 four 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.
