Design and Analysis of a 100kW Rotary Transformer for XROTOR Wind Generators

This paper presents a design methodology for a high power rotary transformer solution for novel offshore X-rotor wind turbine. The design methodology is studied for both in 2D and 3D finite element method for a 100KW system. The results of current, voltage, output power and magnetic field in 2D model is the same as 3D model. The results verify the design methodology, and that efficiency is high enough to present the rotary transformer solution as an alternative for slip rings in the novel X-rotor wind turbine design. Also, the sensitivity analysis has been performed to show the effect of some important parameters.
