@ jeanna

So, this leaves me still unsure.

Me to. Sorry but I do not know how to find the K value they want in the calculator.

I wonder, because the jt I am using never goes that fast.

The toroid is only one of the factors that controls the frequency. The higher permeability produce fewer turns for inductances. There is an inductance trade off between high voltage and high frequency, but it is not the permeability itself that changes frequency it is the inductance. You can get the same inductance with a low or high permeability core. It just takes more turns on the lower permeability core.

  Welcome back. Things got a little wild while you were away.

Many thanks Bill for coming back.
Your hard work is very much appreciated.


When I am done with my work on some other domains,
I will again have more time to enhance overunity.com
and will install a few new great features and the lastest software updates.

Regards, Stefan.
