Higher voltages give charging at lower RPM speeds. The voltage peak
will be clipped off by the battery voltage anyway. Careful if you ever
open circuit the monster though. My 48vdc battery was disconnected
from the controller and it went up in smoke. I measured 200vac before
I got the short circuits back in.

no way? thats nasty have you got any driagrams of your system or photos? i'm
mainally doing research for personal use at the moment so anyother systems
thatt i can look at are much welcomed.

I have created schematics for my wind turbine controller after a few
parts went up in flames. I have modified the circuit so it is less
likely to do it again. They had a 7812 regulator to run the level
detection circuits and because it's input has a max 30vdc they used an
LM317 down regulator to feed that. The inoput to that chip is max
50vdc and it was destined to burn up on a 63v (totally full) battery
sooner or later.

The control circuit is pretty simple two 3 phase full wave rectifier
bridges. One feeds the battery bank and one feeds a couple of voltage
level detectors. One is for low voltage cutout and drops out a relay
to disconnect loads upon dead batteries (42v). The other voltage level
detector (63v) detects over charging the batteries and picks up a
relay putting a heater laod and two muffin fans to disapate some of
the enery from a highly active windmill.

I'm not entirly every componant,chip and circuit out there lol. what would
be he direcht benifit of changing to the TL?
