Abstract:
1. A wind turbine, comprising: an electrical output device including a plurality of winding portions; at least one wind driven blade operatively coupled to the electrical output device, wherein movement of the at least one wind driven blade produces output from the coupled electrical output device; an inverter coupled to the electrical output device; a bi-directional inverter coupled to the inverter; a storage device coupled to the bi-directional inverter; a controller coupled to the inverter and configured to control the output of the electrical output device via stall regulation; and a shutdown switch coupled to each of the plurality of winding portions, the shutdown switch being capable of increasing current based torque opposing operation of the wind turbine; wherein the stall regulation is controlled via shorting of at least one of the plurality of winding portions.
