Patent ID: 8278858

Claim:
A permanent magnet generator comprising: at least one permanent magnet; an output terminal for connection to an electrical load; a primary winding through which the at least one permanent magnet produces varying magnetic flux, the primary winding connected between neutral and the output terminal; and a cancellation circuit connected between the output terminal and neutral, the cancellation circuit including a secondary winding through which the at least one permanent magnet produces varying magnetic flux, and a switching mechanism having: a first switch state wherein the cancellation circuit provides no current path for the primary winding, and wherein variation in magnetic flux through the primary winding induces a current through the primary winding, producing nonzero voltage at the output terminal; and a second switch state wherein the secondary winding provides a return path to neutral for the primary winding, thereby providing negligible voltage or current at the output terminal and substantially canceling change in flux through the primary and secondary windings.
