what should we do for making the output of wind driven generator constant voltage and constant current.if high speed wind is blowing will it cause our battery burned out.so should we place a high resistor,by a relay or mosfet.if yes,what should be its ratings.

we are now getting 17V from th output terminals of generator.and at the o/p of regulator ic around 6V,500mA.but with the change in speed this value is changing.so what should be there to make the mobile battery charging smoother.
plz help us...
