12-DC to 24-DC converter circuit needed..

Here's the circuit for anyone who wanted it,
It's has no regulators or transformers. And I simulated and tested it :D
 

The only problem with boost circuit when the source may be like a car battery - 12V so easy to assume so - is that a short on the output will smoke the diode and/or the inductor.
So either correct sized fuse or a polyswitch on the voltage source. I did one similiar circuit and found polyswitch works out ok, still need to check the response time of the polyswitch you choose, a high current diode helps - as you got in your diagram.
 

Why not Simple transistorised circuit if not load is too high? A simple circuit with astable multivivrator with buffer and Diode Capacitor half wave rectified voltage doubler. Reduce the Capacitors in the astable multivibrator to increase frequency.
Increasing load current will have to replace final transistor with Power Transistor.

Hope this may works.

Thanks for your help, I'll simulate it. :)
