How do we use step-up transformers to get a very high voltage compared to the initial voltage?
In some medical equipment like CT we find that the voltage entering the equipment is around 380 V, but then it's increased to be around 70 kV to 140 kV.
To increase voltage we use more turns on the ...

Why is the output on my high voltage generator producing more amps than I would expect
I recently bought a high voltage generator of off amazon that apparantly steps up 3-6 volts to 400kV. I wanted to know how much amperage the output woud produce out off curiousity and measured it to ...

Turns ratio of transformer not on datasheet
I'm currently looking for transformers to generate high voltage spikes (several kV) on the secondary by suddenly changing the voltage (and therefore the current) on the primary. Ideally, I'd have a ...

Finding the optimal voltage for a sealed transformer
I stumbled across a sealed transformer (step-up) which i believe came out of a neon power supply. Its completely covered in epoxy like goop and the internals cannot be seen.
However,on the tin it ...

Simple, compact 9V DC to 400V DC step up
I'm attempting to create my own Geiger-Muller counter based on an old, soviet STS-5 tube.
I want it to be as compact as possible. I don't want to use ready-made modules, like this one, instead I ...

How can I rectify up to 85 kV?
I've recently gotten into eletrochemistry, and I found out that if you break through \$\epsilon_{0}\$ with a high enough voltage you can ionize various gasses. I've already wound a 1:1250 EE core that ...

Specifying parts for Induction Heater; how to determine current requirements at transformer? [closed]
I'm working on specifying parts for the following circuit:
I intend to have a very large work coil, (like 12" diameter) so I'm expecting to need a lot of power. I'm on a tight budget, though, so ...
