It is because it does work, but not properly in TC application. Another
reason is, that the "new generation" coilers are not any longer
interested in such technologies, they preffer IGBT's and such stuff and
go for DRSSTCs....
Many years ago I did some experiments with saturable reactors. I used
very big welding transformers (3 phase). I used the coil on the middle
leg for control (variable DC current up to 20 Amps) and the two outer
legs for load windings. Results were, that I was not able to get the
desired power level even not by paralleling 2 of this devices and some
other strange behavior. To make a long story short, it worked basically
but I came to the conclusion, that a normal balast with air gap is much
easier and better. Some old videos of my experiments:

Why is it that Saturable Reactors are so rarely used in HV Hobbyist
applications such as Tesla Coils?
We've been using Variacs for generations, we're great at Voltage control.
But when it comes to current limiting the hobby world tends to fall short
and go with some incredibly crude solutions.
Saturable Reactors seem to be the MiniDisc of the HV world. They work,
they're an elegant solution, but they're hard to find and weird so nobody
ever uses them.
Thoughts? Opinions? Wild conjecture?
I'm genuinely curious and hoping someone has some ideas on this.
