Wind power is a major success story in renewable energies. Wind turbine size varies in a wide range, from a few kW to several MW. Most economical scale is in 1 to 3 MW range. It is in the perfect range for APS’s SiC device to optimize the power efficiency. Most popular power electronics in large wind turbines are synchronous generator along with a rectifier and inverter for grid interconnects. Our SiC devices can greatly reduce the size and overall system cost of the rectifier and inverter system.
