  • Variable speed wind turbine having a matrix converter
    Patent number: 6856038
    Abstract: A variable speed wind turbine is disclosed comprising a turbine rotor that drives a doubly-fed induction generator, a matrix converter which converts variable frequency output into constant frequency output, and a control unit and a protection circuit for the matrix converter. Power is circulated in the system allowing for sensorless detection of rotor position and better output ratios of power from the system.
    Type: Grant
    Filed: March 24, 2003
    Date of Patent: February 15, 2005
    Assignee: Vestas Wind Systems A/S
    Inventors: Anders V. Rebsdorf, Lars Helle
