A variable ratio gear system is configured for use with a constant speed generator being driven by a variable speed rotor. The variable ratio system includes three shafts: The first shaft is mechanically coupled to the rotor; the second shaft is mechanically coupled to a variable gear system; and the third shaft is mechanically coupled to the generator and the variable gear system. A control system is configured to adjust the output of the variable gear system to control the rotational speed of the generator. A brake is configured to control the rotation of the second shaft.
