Hi all,

I have at max 22AC output from a small generator and want to convert it to DC, I am pretty sure i need some Diode's to do this (ampage is not that high although i am unsure of how to test the AC amps on my multimeter), What sort of Diode should i use? and how can i configure them?

Thanks
 
Thanks for all the replys lads, very helpfull.

a little more info, I am basically teaching myself electronics by creating small projects, this project involves using a pc fan re-wired to generate a voltage when the fan is spun, now I measure the AC which tops out at 22 volts on full push, obviously this current makes the attached LEDs flash so I wanted to convert to it to DC first, then as you have said I should add a small capacitor, eventually I may try making a voltage step up circuit.

The fan is rated at 0.18amps, is this the likely output of it being used as a generator? I don't quiete get the suggestions on measuring the amp output in AC. Can someone "lamen" it up for me please :).
 
Thanks for the help, its up and running now, I qm thinking of putting a couple of AA rechargeable batterys on it which I am hoping will trickle charge from the turbine.

can I just wire these batterys up to the DC output? I assume I would need to some of protected circuit?
