Looking for some help, please. I don't know much about electronics - studying hard at the moment.
I need to make as cheaply and simply as possible a 15kV (or thereabouts) DC power supply with low output current - ideally around 20-25 microA.
(The application is boring; if you know the answer to the power supply, you'll probably guess its application. Please let's not have a thread about the application.)
A 3.7V 18650 battery should have enough juice, but I don't care too much about the input.
This thing is frustratingly close:
https://www.ebay.com/itm/382131734381
It outputs 15kV AC
The specs say output current is 0.4A, but of course that's not right, it must be 0.4mA.
I guess I can reduce the output current by replacing the resistor?
Is there a cheap and simple way to make a rectifier for the output?
Or a similar transformer with lower voltage output that I can add a voltage multiplier to?
Or any other kit or cheap prebuilt unit that gives around 15kDCV at around 20-25 microA or could be modified to be close?
Thanks, guys
