design 9v to 1000v transformer

[hoachealsea]

Hi , i am new member ,I plan to do a circuit , i see in internet 9v to 1000v transformer but i dont see schematic ! Can you give me schematic and amperage that the circuit output , the equipment needed to make this ? i am very thanks you !!

Hello hoachealsea , welcome to ETO!

I'm not quite sure what the question is. A transformer is simply two coils of wire wrapped around a core. The ratio of the voltage is the same as the ratio of windings on the two coils. In order to get 1000v from 9v, then the ratio of windings would have to be 9:1000. The simplest example would be 9 turns on the primary and 1000 turns on the secondary, but realistically you'll probably want, say, 45 turns on the primary and 5000 turns on the secondary. It all depends on how you plan to drive it.

Just as the voltage is directly proportional to the turns ratio, current will be inversely proportionate. The formulas are as follows:

Voltage:

Current:

Where N1/N2 is the ratio of turns on the primary/secondary.

So let's suppose you put 9V at 1A into the transformer. The voltage will be:

And the current will be:

In order to make such a transformer you'll need lots and lots of wire and some sort of core. The core material you use highly depends on how you expect to drive this transformer, and what frequency at which you want it to run. This is all the information I can really give you with such a cryptic post such as yours.

Regards,
Matt

Welcome to the forum.
What is your knowledge level?, if your a novice then you'd be better building someone elses design rather than doing your own.
Do you need 1000v exact, or just high voltage.
This project generates 10-20kv from a 9v battery:
