Low volt capture

[richard cross]

Hello
I have a wind generator which charges into 12 volt batteries.When there is low
wind but I see up to 11 volts on my meter being generated but no charging
I want to use these wasted volts/amps.I beleive that capacitors and/or
a transformer are used to do this.I would be happy to see the battery being
pulsed as beleive this is good for them.Can anybody help with a circuit and
Cap values etc.
Thankyou Richard

You could accumulate the low votlage DC in a big capacitor, (Farads!)
and use a Boost DC-DC converter up to 13.8 Volts.
The system inherently pulses.
I tried this with solar PV panels. (early morning, late evening.)
The energy available in low wind conditions is not worth the effort,
but it's an interesting exercise.

I would be happy to see the battery being

and
Cap values etc.
Thankyou Richard

Why are you thanking Richard?
