SiC’s potential impact on the design of wind generation system

The potential impact of SiC devices on a wind generation system is explored by simulations in this work. The system modeling is explained in detail. Most recent SiC MOSFET prototypes are obtained, tested, and used to form a bi-directional converter in the simulation. The performance of the SiC converter is analyzed and compared to its Si counterpart at different temperatures and frequencies. A conclusion is drawn that the SiC converters can improve the wind system efficiency, conserve energy, and reduce system size and cost due to the low-loss, high-frequency, and high-temperature properties of SiC devices even for one-for-one replacement for Si devices.
