DC output wind turbine demonstrator, based on isolated DC-DC converter with Silicon Carbide semiconductors

Power density increase, price reduction of the solution and efficiency increase of the Wind Turbine Converters and windfarm grids are one of the challenges in the Wind sector. For that purpose, Power Converters and the use of Silicon Carbide semiconductors is a promising solution due to the enhanced performance in terms of switching behaviour and passive element reduction. This paper is focused on the use of Silicon Carbide (SiC) power devices for wind applications, combined with a new conception of Energy transport based on HVDC distribution systems. The solution proposed and developed for this paper is a DC output wind turbine, composed by isolated DC-DC converters based on Silicon Carbide semiconductors.
