I am trying to build an air core transformer. It must operate between 900khz and 1.2mhz. I would like the input to be as little amps as possible (.01A) and the voltage to be up to 250. I know how to read a basic schematic but am not sure on the specifics I need to build it. I already have the transformer built and just need help with the input.

So what is the easiest way to produce 250v, .01a, @ 1mhz?

If I am missing any information please let me know.
Thanks for any help,

What is the purpose of this kind of transformer ?
 

Actually it is already built but I don't know how to get the input I am looking for.
The purpose is to just put high frequency AC through it and see what comes out of the secondary. I know that a air core will lose all kinds of flux but that is not a concern. I just need to put very low amps, high volts, at a high frequency through the primary, any advise?

Thanks,
Abudantia
 

If I'm right you need to know how to drive such a transformer
 

Maybe this link could help you.

**broken link removed**

As far as I know, this circuit's basic idea is to continously charge the capacitors, so the voltage sums to the one existing. Thus the input power is the same one, so at same power, when increasing voltage, current will have to decrease... So let's say 250V at 0.1A, it's 25VA... You should generate a 25VA signal input in a voltage multiplier, and as voltage increases, current will decrease.

This is just an speculation, i'm sure i am wrong somewhere :D but maybe the basic idea lets you somewhere else...

Let me know if this helps, or what else you achieve.

What you said makes sense, because if the voltage is twice as high then the amps must be 1/2 of it.
That website helped out quite a bit.

I think I am going to put in DC and run it through a 555 timer and a couple of other things and convert the pulsed DC into AC once it goes through the transformer.

If It doesn't work or I have any other questions I will be sure to ask.
Thanks halls and everyone else for the advise it is much appreciated,

Abudantia :D
