Moreover, the generators windings may also be damaged by a large short-circuit current. In this paper, the electric braking circuit using the NTC thermistors (negative temperature coefficient resistors) is proposed as a braking system for a cheaper and safe stop of the small wind turbine. The effect under the natural wind condition is examined by the field test using a 500W small wind turbine.}, pages = {910--915}, publisher = {IEEE}, title = {Braking Circuit of Small Wind Turbine Using NTC Thermistor under Natural Wind Condition}, volume = {2007}, year = {2007} }
