Re: Ferrite question - continued.

It wouldn't take much to couple that capacitively into
things in the general area.
I disagree. to get 40A , one has to apply 200V/25ns dv/dt to 5nF. One
needs to work hard to get parasitics that high.
...how you are driving the primary. What's the primary inductance?
I replied to legg with the answer to this question

What's the primary current as a function of time?
Hard to tell...Ferroxcube TX29/19/15-3E6 1 turn has 13uH
....
Hint about core saturation: you should be able to see that with no
secondary on the core. If you put a step voltage...
I have a jig to do it (have been going to make a PCB to minimize
parasitics for...years)

There is no sharp bend in current, is there?
