Electronical electrostatic generator

[alitaban]

Hello
I wanna a circuit for a modern electrostatic generator for about 30kv-1mA
like this product https://takk.com/specials/ElectroStaticGenerator.htm
but I don't know foundamental for relating electronic & electrostatic
if you know please how can I make it?notice that vande graph is very poor efficient!

Electrostatic stands for static potential or voltage in a medium.
You can generate static voltages by the century-old method of using friction and induction. Other methods use Tesla transformer to generate high AC voltages, then HV rectifiers to charge a Leyden jar or other suitable capacitor.

Van de Graaf generator is not "poor efficient" as it slowly transfers small charges at a low voltage above ground by moving insulator (paper) strip, to be collected at a high-above-ground ball as an extremely high voltage charge.

You can try your method if you want. Th electronic method replaces a mechanical interruptor of a Tesla transformer with an electronic switch (a transistor), and the output high AC voltage (up to 30 kV) can be rectified with an "electronic" rectifier - a stack of silicon diodes. You can find similar circuits in the now obsolete CRT monitors and TV sets.

No,I want real electrostatic.means a lyden jar with charge.
in CRT monitors only used HV but I want to save negative HV
I produced about 10 kv 30map with a flyback transformer but and connect it to ground and other side to an aluminium foil
and aluminium saved a middel negative charge(spark to my hand in 3mm)
but this charge is very low rather than a wimshurset machin probably this method has very waste.

From what you wrote it is quite difficult to understand what you know and what you want.
BTW, how can you tell the HV polarity from an electrostatic generator? What type of voltmeter have you used?

Yes, the posts are confusing/mixing some points.
- A DC HV source can be specified by voltage and current. It's behaviour doesn't depend on the circuit connected to it.
- An "electrostatic generator", as linked in the initial post is a combination of a HV DC source and an ion generator, e.g. utilizing field emission or glow discharge in air.

A CRT anode supply generates a positive voltage referred to ground, e.g. 25 kV/about 1 mA for full standard color TV. If you want negative voltage, you have to design something different.

ES voltage=( charge/area of charged thing) in compare with

( ground charge/area of ground)=0
I Haven't an ES voltmeter but my transformer produce about 13KV.


13kv is clear
30 ma means take a current= 30mA from source without decreasing in voltage.
so our generator has a produced power about 390w!

From your writing I can see you have a zero knowledge of electrical engineering.
Please go and study. Talking nonsense makes no progress.

now you're mistaking.I know V=q/A and current=q/t and power=IV
so those were true.
these challanges only waste the time.
I wanna https://takk.com/specials/ElectroStaticGenerator.htm please say you can help me?
