running a tv cascade of a 15kv 30ma nst
Download, Mon Mar 12 2007, 01:24AMhi all
i was wondering if a tv cascade would die if i ran it off a 15/30ma nst? i have two of them but i dont whant to kill them and what would the output voltage be (aproxmate)
would this work?

I would think it would not work because TV cascades are meant to run off the HF output of a flyback not a 60hz transformer.

Like Nik said, the frequency is much too low to get any decent output from a NST.
The flyback runs at 15khz, as opposed to .05khz that your NST runs at, which (due to the design of the cascade) will only get you a tiny fraction of the power you could get using a flyback.
It is possible to make a doubler/tripler/ets for a NST, just get yourself a bag of 500 in4007's and some doorknob caps (or any string of caps good for 30kv) and start making doubler stages.

i have go 10 30kv doorknob caps and i need to get the diodes

wont those diodes fail since you are far exceeding their max voltage rating?

You string a bunch of them in series (input KV * 2 is usually enough, probably best to use 4 for an added safety margin) which raises the max voltage

Don't forget some ballast resistance on the output stage to limit the current.
