Modulation features of a high-frequency conversion system for wind farm applications

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 demonstrates good behavior of the voltage in the high frequency transformer and low harmonic distortion in the three phase current.
