Converting the power

Shujun Zhang introduces in this lecture various principles for electrical power conversion

This lecture introduces power converters for doubly fed induction generator and permanent magnet synchronous generator. Functions of different components of the power converters are explained. Modular multilevel converter for offshore wind is also introduced. Its work principle is explained.

After viewing the lecture, you will have knowledge about the power converters used in offshore wind.

Learning outcomes

On completion of the lecture, you should be able to:

  • Explain how a doubly fed induction generator works in offshore wind
  • Explain how a permanent magnet synchronous generator converts and feeds the power to the grid
  • Explain how a module multilevel converter is used in offshore wind


After having watched the video, you should reflect upon the following

  • What are the pros and cons of the doubly fed induction generators for offshore wind?
  • What are the pros and cons of the permanent magnet synchronous generators for offshore wind?
  • What are the differences of the three presented generators for the offshore wind?
