1. Apparatus for controlling the transfer of electrical energy from a multi-speed pole amplitude modulated type dynamo electric machine powered by a wind machine generating alternating current to a primary electrical circuit comprising:
- a. an electrical conduit between said dynamo electric machine and said circuit;
b. a breaker for selectively opening and closing the flow of electrical energy through said conduit; and
c. a current limiting reactor and associated means for connecting said reactor in series with said conduit during a transition from a low rotational speed to a high rotational speed of said dynamo electric machine.

Abstract
Wind turbine generator systems incorporating a multi-speed pole amplitude modulated type dynamo electric machine allowing efficient operation at consecutive speeds in a ratio preferably less than 2:1. A current limiting reactor, preferably including an inductance coil, and an over-running clutch, are utilized in conjunction with any multi-speed generation system to alleviate impact on a utility grid during switching among operational speeds.
