Wind turbine for battery chargibg

Mods feel free to move to wherever you think suitable.

I am revisiting an old failed project which used an induction motor as generator to charge a battery.
IMAG is explained here.

Primer on invertor topologies here

Its prompted by a recent thread here

The problem is that using a rectifier and cap it causes the excitation field to collapse.

It is partially solved by using large inductances or transformer on the input but its very ineficcient.
Switching inductors depending on wind speed helps some.
What I would like to do is use arduino to perform intelligent inductor switching while at the same time using smaller inductors by utilising convertor switching.

Is this a feasible idea ?

More information.

Im thinking along these lines but single phase.

L4 switched according to speed.

Its actually a bit more complex filter than that as l4 on its own dos not work
