im looking for a voltage multplier

ebay has them but for for $16 (with shipping)

if anyone has a spare around let me know

ill also be looking for a broken TV as the junkyard this weekend

As you don't give any suggestion of what you actually want!, how is anyone supposed to help?.

This is like asking for a "piece of string", with no indication of length, thickness, or what it might be used for?.

This should be put up as a sticky for every question that comes up without a decent description. Good One Nigel

I had no idea they made diffent outputs for these ops:
umm... any one will do

its going in an electronic torch ighter i made

i thought i posted it here but when i checked i could not see it

here are some pics

its an inverter and and 9V battery with a spark gap on the output

If you multiply its couple of kV output, the current will be divided by the same amount. You know, power in must equal power out.
Then the spark might not be hot enough to light your torch.

If you need a higher output voltage and the same current as now, then the circuit and its battery must be re-designed for it.
The little 9V battery is probably operating flat-out right now. It won't be able to supply 10 times more power. The same applies to the circuit's transistors.

Not if it was powered from a little 9V battery. :cry:

My propane barbeque grille came with a battery powered ignitor that would throw a spark sufficient to light the grille -powered by a single AA cell. I suppose you could simply purchase a replacement part thought that isn't a direct answer to your question.

well the guys on the revies say it will take up to 15 volts at most and im not powering it for long

ill try adding some more voltage into it

maby 2 AA batteries

here is the link to the inverter at allelectronics.com

http://www.allelectronics.com/cgi-bi...V-7&type=store

now if that link does not work (had problems with this before) go to the site and look for inverters at the right, the first one on the list is the one i have

they also sell a bigger one that i think ill pick up to try next time i order from them

It says it is made to power a Compact Florescent light bulb, so I guess its output voltage is only about 170V or maybe doubled to 340V, not kV's.
It is designed for only 5V so why use up to 12V? It has a MOV on one end which probably limits it max output voltage anyway.

It's too bad that it doesn't have spec's nor a schematic. It does have a cheap price.
I bet it has a two-transistor multivibrator which wastes a lot of power if its supply voltage exceeds the 7V reverse-voltage rating of the transistors' base-emitter junctions, causing avalanche-breakdown.

You know what's inside a little 9V battery? Six skinny AAAA cells. Not much power for breaking-down transistors and MOV's. I would power the thingy with four AA cells.

The module (CXA-2090) was made by TDK, so I doubt that it is poorly designed. It's probably cheap because it's surplus and obsolete.

I see a LOT of faulty TDK inverter modules failing in VCR's, I've never been impressed by their quality!. They are (sorry WERE!, you don't see them much now) often used to generate the various voltages for VFD's on the VCR.

OK, maybe it's surplus and obsolete for that reason. ops:
