most simple and smallest way to charge a 6kV capacitor?
I need some ideas on what type of DC-DC or DC-AC converter I can use to convert 9V into 6kV.
the 9V will be a standard 9V battery. The output current doesn't need to be high. It's for charging a 6kV capacitor, and this May take a few seconds.
It doesn't need to be charged in a few milliseconds.
My own suggestions are these:
- DC-DC booster (switching a coil to get high voltage spikes) but these only generate 200V max I think
- DC-AC inverter like those small CCFL inverter circuits
- Flyback - not compact enough
- booster or inverter connected to a marx generator - but also not compact enough
any other ideas?
It also doesn't matter if the output is AC or DC, I'll just add a HV diode to rectify it. Although, that also takes some space and it has to be Really compact.
I know that converting 9V into 6kV might not sound like a simple thing, at least if I want to do it in one stage, but I've seen videos where people convert the voltage from a 1.5V battery into 4inch sparks. (that was with a marx generator too though).
