Alternator voltage boost conversion
This is about the only place I thought this might fit in but if it isn't I'll try and find another forum somewhere since this isn't precisely an automotive application. Is there a Shade Tree Prepper section here?
Has anyone out there converted an alternator to a generator outputting about double the usual D/C voltage? I've seen several videos on YouTube boosting the D/C voltage to around 15 volts or a little more in various ways but I was wondering how far you could push this? Could you put enough voltage into the rotor excitement to output 25 to 26 vdc with an appropriate regulator? Is there a formula for voltage on the rotor to derive the output of such a modification?
I'm not looking to apply this in any automobile. I'm trying to figure out how to charge two deep cycle 12v batteries in series (making a 24v system) on a single modified alternator. Hope that makes sense.
Thanks.

I guess it depends on how many windings you use. From what I'm seeing in the videos if you use 2 out of the 3 and you spin it fast enough you wind up with 220v which is a bit more than I need.

Thus, the reason for the regulator. They make external voltage regulators, the type you need, but they are not cheap. You may be able to search and find out how to build one yourself. The solar people make the external regulators, but they are around $500 at the places I looked. You can have 12, 24, 48v to charge different configurations of batteries. If you could find a military surplus place, you might be able to find a complete alternator cheaper. They ran 24v on their vehicles.

They did? I'll definitely check that source out! Thanks.
(Edit)
Ok, over on Ebay they have a lot of 24v alternators mainly for ag equipment. Duh. Didn't think there really was such a thing but I guess a lot of military equipment has its roots in the Ag Industry. That does simplify things a lot.
