Hi,

I am trying to figure out how I can make a regulator for a small wind
turbine. The output is to charge 12V lead acid batteries.

The turbine outputs from 0-110V - (usually around 20-30V). The normal
approach is to regulate to 13.8V, and dump the excess voltage through
a shunt resistor. However this seems very wasteful, and I was
wondering if there is a way of converting the excess voltage to
current?

meci.com had a bunch of DC-DC convertors....
