help on designing or building a special PSU
«  »
Hi!

I am seeking a special kinda HV source and it seems these are hard to come by.

I would be willing to pay for the schematic or even building one of them, if some of you have the will and expertise to make one.

If you think you could help, please drop me a PM

Which voltage levels are you looking into regulating?
One or more phases AC, PWM DC, variable or set switching frequency?
If I can help you it wouldn't cost you anything, I'd be more than glad to just help you out if I can :-)

Well I would like to get out DC pulses from 0 to at least 2kV (10kV if possible). Control over the frequency and width of the pulses.

Really sharp rise times if possible. Amps are not in my interest, but judging from some NSTs 20-40mA

Output from a single terminal.

I can kinda get there with a neon sign transformer and a HV diode, but then there is no freq control, voltage control and it is half of a sine wave so the "rate of change" takes a hit compared to a sharp DC pulse.

This arrived in the mail

but the manual says if I try to pulse something without connecting the return lead it will blow up :(

Alright, I'll see what I can find.

Something between 2 to 10 kV, there in lies the biggest problem (I.E challenge) to get sharp edge transitions (low to high and vice versa) given that the voltage is relatively high without having it dropping all too much from whatever tank circuit / high voltage DC link you'd be looking into replenishing regularly, which then would be serving as a source for the switching transistors at hand.

But I have a few ideas, I'll see if there's any readily available google images which can help explain what I mean.

Actually would be nice to have it from 0V up, so you can mess with resonance in low voltages.

I mean I would gladly take a source with less voltage, if I can control the freq, voltage and get this pulse out of one electrode.
