Medium Voltage Full Size Converter

    Woodward CONCYCLE® Medium Voltage, Full Size Converters
    for Permanent Magnet Generators

    Woodward’s CONCYCLE® medium voltage converter was especially designed for operation in offshore wind turbines, and is the optimal result of our years of experience with offshore converter installations.

    This converter was specifically developed to offer a small converter with fully enclosed cabinets. This was made possible by a sophisticated water cooling system for maximum efficiency of your wind turbine.

    The excellent reliability and quality of CONCYCLE® wind converters result in a perfect power generating system for variable-speed wind turbines. Intelligent control of the converter complies with all valid international grid code requirements at the point of common coupling.

    Woodward's CONCYCLE® medium voltage converter design covers your power classes from 4MW to 10MW.
