Abstract
A wind turbine generator comprising: an electrical generator configured to generate AC signals, a plurality of power converters operated by a gating signal, each power converter configured to convert the AC signals from electrical generator into fixed frequency AC signals, a transducer configured to measure the combined output from the power converters, and a controller configured to phase-displace the gating signal of one of the power converters to substantially minimize harmonic components of the combined output.
