Well, we'll probably have to disagree on this.  Why has Sola had a market 
for the last few decades?
I'd be interested if you would share what you know about ferro-resonance. 
Although I've been in power conversion for 30 years, I can always learn 
something.  I try to learn something every day, and when I do so, proclaim 
it a good day.

I used to build & test them.
You don't get something for nothing.
If your load is dropping the input voltage, a FR transformer will drop it
even more, increasing current draw, dropping input voltage, increasing
current draw & so on.
If the circuit finds equilibrium, great - until someone adds another load.
A carefully designed system, which includes a FR transformer should be very
stable - it's not just something to add to just any circuit to get stable
output.
