Homemade HV transformer
« on: September 14, 2019, 05:05:00 PM »
Hello!

I would like to ask you, who has made several high voltage transformers here? I was experimenting with television flyback transformers, it could produce a piece of 30kV. They can be connected in series but I want to make my own, my goal is at least 60kV. Do you think this is possible? Included are two forms of what ferrite core I found, so I should design a secondary one.




I drive with this switch ..

I have a 3d printer, I could print what I need, but unfortunately I haven't designed one yet. I will need to drive an X-ray tube, then I want to apply a voltage multiplier.

Thanks! I don't see any specific electrical voltage, nor is it written by any person who built one. Do they measure voltage? I see a 14-20kV post, but it is very little for me

Hi  :)

what core is in the picture ?
I have the same project, but with a lower voltage (20kV)

I suggest for the bobbin a milled HDPE cylinder because 3d printed coils have air bubble, so partial discharges can occur

cheers

Thanks for the help! I have a dental X-ray and I want to operate an X-ray tube. The question is how much tension to multiply, what do I manage to produce for myself.

I usually do X-ray fluoroscopy videos, this is my own:

The tube I want to operate requires 60kV:   (I'd like to operate this tube)



This is a "siemens röntgenkugel" x-ray tube

Presuming you need 60V DC, it's probably easier to use a somewhat-lower-voltage transformer and a voltage multiplier.  For my Marx generator, I wound a +-11kV transformer followed by a voltage multiplier to get +-22kV DC
