Windgen regulator

SansSerif said:
We're currently fitting a KISS wind gen. This has a manual brake switch and separate rectifier. This http://www.ebay.co.uk/itm/Controller-for-Wind-Generator-Turbine-PMA-Upto-600W-Wind-turbines-12v-or-24v-/350973749510?pt=UK_BOI_Industrial_Tools_Generators_ET&hash=item51b7aa6906 seems to be a reasonable substitute. Am I missing something?

Assuming your wind gen is a 3 phase generator ....... ( 3 wires out to the existing rectifier ) that should do the trick if your wind gen is within the 100 to 600 watt range.
 
From my little experience with wind gens regulation is not the problem compared to getting enough voltage to charge a battery. If you have a 3 phase rectifier then try connecting it to a 12v battery via an amp meter and just see what it will do. If it does provide a lot of cjarge amps at normal wind speeds then yes you need a regulator. It could however feed the battery direct if voltage is not so much.
A 3 phase rectifier consists of 6 diodes. Each of the 3 power wires go to the anode of 3 silicon diodes. The cathodes of these 3 diodes joins toghether and become +ve output.
From the same 3 power wires ie doubled up with the anodes you connect the cathodes of 3 silicon diodes. In this case the anodes connected togehter becomes the -ve output.

I found however that schotky diodes work a lot better having a smaller volt drop ie .25v cf to .7v giving charge at a lower wind speed.

If you want a regulator then I would consider an MPPT type controller for solar panels might give more charge especially on low wind speed days. (needs a recifier of course).

good luck olewill
