Hopefully you get them at a bucked deal, to produce 800 [eight hundred ]
volts from a battery pack you will need a lot of batteries. Probably want to
invest in a small fork lift or good size hand cart also.
You can construct one from approx. 534 2016 button cells in series. Singly
stacked, it would be about 2'9" high; stacked in 4 columns, soldered in series
would be an approximate 3"x3"x8" cube -- not too bad for 800v. Smaller button
cells could get the size down further, if needed.
HI' I am YAR
how many ampers you will used?
generaly you can get this(800 volts ) with 12volt with any circuityou
can convert the DC to AC volt & then use a transformer to nearly
200volt then used two voltage doubler to get the 800volt you want
If you agree send me an email and I will email you the circuits
don't search for this batteries
It is called a DC-DC converter.
Crudely speaking, the input DC powers an oscillator which drives a
transformer to create the new voltage; the output is rectified and
filtered to give DC.
That oscillator can be a push-pull square wave, or can be a
(single-ended) flyback or similar design.
It is called an inverter. You can get them for your car, rv, boat, or other
similar personal conveyance, where they plug into your cigarette lighter or
similar power-point and have 1 or more 120 VAC sockets.
Same thing with computer power backup systems (or uninteruptible power supply
They are used on a larger scale for emergency power systems where a temporary
outage cannot be tolerated -- there will be some large-scale UPS, typically
powered by submarine batteries that immediately kicks in on a power brownout or
failure and keeps the system energized until the fuel-powered generator comes
About 90 or so 9V PP1 batteries in series will do the trick. No wiring
required either, just clip them together directly "end to end". Not
exactly a robust or elegant solution though, although I suppose you
could glue them together to make it more robust.
How much current do you need?
Don't use a DC-DC converter if you want low noise.
