Abstract

The slip ring solution for power transfer between rotating structures has adverse impact the maintenance of offshore wind turbines. In this paper the design, performance, efficiency, and manufacturing details of a 1 MW wireless power transfer system for the novel X-rotor offshore wind turbine concept is presented. The results show that this design methodology that includes rotary transformers and dual active bridge converters is suitable for high-efficiency high-power wireless transfer systems.
