Hello!!!

NO PROBLEM TO FIND HV CAPS: JUST TELL ME WHAT YOU NEED!

I'll sheep them to you.

....just the same...no problems to obtain high voltage pulses without using ..valves!!!!!...I've just to wait for ordered parts.....but I'm not so sure I need them!!!

All the best from

@Wattsup,

Well I thank you so much for your words but eventually you will discover, like I did some time ago, that NOBODY  does want to team so you are left alone with your problems: so doing lot of precious time is going to be dispersed duplicating at least almost the same efforts. Exceptions to sayd rule fortunately does exist even if in some degree, namely: Otto, Gustav22, JDO300, GK, Wave Watcher, Esa Mauno, Eldarion, etc.

To speak about the 'now existing issue' for myself: I'm deeply concerned into designing a new class of electronics able to deliver in an efficient way the HV pulses (...Otto reference) needed to TPU V10-7.
I've now setup a SPICE environment so most of the guessing work is being done by simulation...it's time to get advantage from PCs  (OK I did it already in my life in the sixties!).  To speak clearly there are many, many possibilities to do the work by using the now available HV IGBT  (1700V/30A - nanosecond rise time is enought?) ...just doing the design!  If anyone already did it: it means if  there are already SPICE models  (both schematics & IGBT models)....don't let me re-discover the circle.  Anyway no-problem as long as I'm really having fun while playing such a game as it's my actual ground ...much like valves in the sixties!

Hello all,

@Roberto,

thanks for your offer, maybe.....I have first to see if I can buy old radios with tubes and the wonderfull double air capacitors. The big dirty one, from old radios, with metal plates...

Now I want to describe a little what I want:

1. a 20 - 25 kV power supply
2. 3 tube oscillators with sine waves. This sine waves should have sines in the range of ...say...over 100V.

The high voltage can be made with our coils like in the ECD: primary and secondary coil connected on 1 end together and we have a high voltage.
The 3 stack is shown without secondary coils because the picture showes ONLY how to wrap the coils. The secondaries are NOT shown.

Now imagine to pulse coils with such a setup!!

X - rays.

Very high speeds of particles.

Low current used.

Otto,

I do agree with you as another way is just to use an ECD to provide for HV pulses  (we do know it very well, isn't it true?): perhaps is the easiest way. As you do know very well this is an old idea...that until now nobody actualized!.....the reason is that IT'S DANGEROUS.

I do still have some ECDs...so It will be easy also for me to check....but...perhaps it's not needed as I do already have what I've looked for since a long time: I've just to decrease the mosfet internal losses...then, as I see it,  it's DONE.

If what sayd will be succesfull only then I'll do 'refining'...but before this there's still the 'inital phase' to understand & setup.

@Roberto,

yes, its very dangerous. I had the "nice" expirience to feel a high voltage with my fingers....

I have always the same question: when a HV hits your fingers then (/&%% but when it hits your coils with a 100W bulb it seems that no soooo much energy is in this coils. Hmmm....

I hope you found what we all need. I hope it because then we have all done our work.
