In this paper, the concept of an all-dc wind park with series-connected turbines is investigated as an alternative to the classical ac parallel or radial wind park. This paper presents a literature overview of all-dc wind park concepts with series connection. A three-phase conversion system with permanent magnet machine, ac–ac converter, high-frequency transformer, and diode bridge rectifier is suggested...
This paper presents some modulation features of a high-frequency link based on reduced matrix converter for offshore wind farms. The topology consists on a reduced matrix converter, a high frequency transformer and a full-bridge diode rectifier. The converter is operated as a current source. An experimental set-up of 10 kW was used to demonstrate the feasibility of the proposed modulation. Results...
