Abstract
A variable ratio gear system is configured for use with a constant speed generator (104) being driven by a variable speed rotor (102). The variable ratio system includes three shafts: The first shaft (144) is mechanically coupled to the rotor (102); the second shaft (160) is mechanically coupled to a variable gear system; and the third shaft (158) is mechanically coupled to the generator (104) and the variable gear system. A control system (109) is configured to adjust the output of the variable gear system to control the rotational speed of the generator (104). A brake (188) is configured to control the rotation of the second shaft (160).
