Multiple induction type generators are drivingly connected to an impeller. As wind velocity increases, the generators are successively activated until all of the generators are operating at a maximum wind velocity. As the wind velocity decreases, the generators are successively de-activated until all of the generators are inoperative below a minimum wind velocity. Wind energy is more efficiently converted into electric power where impeller RPM must be maintained substantially constant under varying wind conditions to achieve the desired constant phase of the AC output.
