i was planning to use an automobile induction generator with a belt and pulley system to give enough rpm to the generator. one of my friend suggested me to use a DC-DC convertor to regulate the voltage output.

if i would use battery, then there is no problem at all but i don't want to use battery because of some issues. Thats why i am looking for an alternative to get a fairly regulated voltage from turbine to be directly fed in the invertor.

I guess it'll be 0-24 V. Not sure coz i've not tested the thing so far

battery iz a solution but its not included in my project :-s

Is that just an alternator? You may be better off to stay in the AC domain and never convert to intermediate DC. For one thing, you'll avoid the inevitable power loss in diode rectification. There are ways to convert one AC voltage to another. Obviously a transformer works for a single input voltage, and there is a thing called a Variac for manually adjusting the ratio. You need something fancier.

you're right but there is no other way i have. talking about the variable transformer, it would be difficult for one to automatically adjust it setting accordingly with input voltage.

Difficult, yes. You're asking for the holy grail of wind power - a device that accepts any input signal and converts it to 120v, 60 Hz. That's not simple, and I'm not aware of any general solution.
