ABSTRACT:
A method and corresponding apparatus for regulating a system that produces electric power, the system including an electric alternator having a rotor integral with a rotating part of a wind machine to form a rotary assembly, and a power electronics module, the method including the steps of: producing an alternating current at output terminals of the alternator; converting the alternating current produced by the alternator into modulated pulses of direct current. Alternating electric current produced by the alternator is regulated by controlling the speed of rotation of the rotary assembly by resisting torque imposed by the alternator in response to modulating the pulses of continuous current produced by the converted the alternating current.
