How can I convert a DC voltage 3.6V to DC voltage 1000V?

What current?

10 μA at 1000V

Is that schematic correct? Shouldn't R1/C1 be in the base winding and not the collector winding?

Hi
You can easily use a square wave oscillator and then use a simple cockroft walton to earn your required voltage rating .

google for Royer oscillator.
The trick in these is to get a proper transformer.

Also checkout Villard multiplier, and flyback converters.

Each of these methods have their pros & cons, but it should get you started thinking/ tinkering.

cheers!

Wow. That implies a resistance of > 100MegOhm.
At that voltage, you will have to be very careful on layout & design, since there would be leakage currents through all sorts of paths of currents greater than that.

The Cockcroft-Walton multiplier is a good choice because no single component would need to carry the entire output voltage. Each is exposed only to the supply voltage.

If you use a boost converter to reach, say 200 V...

then you can apply that to a full H-bridge to turn it into AC square waves...

and apply those to a X5 multiplier.

The load is 10M to bring out some ripple. It suggests 10 nF capacitors ought to be sufficient to supply relatively smooth 1kV to a 100M load.
