How to make a voltage regulator for wind turbines

[jonule]

uh you could develop your idea that she looks good elephant?

[elephant]

it's quite simple:

a wind turbine or a solar panel with a given energy capacity for a given sunshine or wind.
To adapt the quantity of energy Q = (I * V) * t, to the needs one proceeds either to a loss of energy in a transistor, or one cuts the time t in pulses.

let's be concrete:
assume that we only need 50% of the producible energy to charge a battery. Either one expends energy in a transistor, or one cuts and one restores in a ratio 1/2 (using a mosfet or thyristor switching circuit).
Whatever happens, half of the theoretical capacity of the generator (wind or PV) is unused.

If using a double switching circuit we derive
- in a circuit A, the optimum amount of energy to charge the battery (variable depending on the state of charge of the latter)
-in a circuit B, the balance, for example in the heating resistance of a boiler.
we then use all the energy that the generator can produce

this cutting is done of course at relatively high frequency (100 to 10.000 Hz)

uh I think my head will explode

[elephant]

well no, even I understand!

[jonule]

OK !
meanwhile flew a typical shunt regulator diagram:

interesting scheme, but only if we can use the heat radiated by the resistance. Be careful that this resistance to the extreme right must be largely dimensioned for such powers: nichrome wire on porcelain or soapstone.

[jonule]

I think we can connect a water heater resistance, right?

we can also shed this energy to any device that consumes electricity such as a fan in summer or a washing machine etc?

[elephant]

Absolutely, but heating water seems to me to be one of the only alternatives given the irregularity of the current.
This resistance must of course be adapted to the voltage, taking into account its variations by Joule effect.

[jonule]

yes, I also suppose that on this account we can also take the opportunity to charge another battery while doing so, a bit like the battery coupler on a motorhome;

anyway there must necessarily have to do with surplus electricity ... the ideal still seems the water heater, of the kind heating resistance on additional balloon or in line on thermal solar panels

yes I was thinking of making a montage with a cascade of tunechager
but it requires a substantial investment
