Maybe my first question Dc-Dc converter from 12v Input 400v Output was too broad for what I was actually trying to solve, which is why I am reformating my question.
I want to charge a capacitor (C=0.68μF) at 400v for a CDI (Capacitor Discharge Ignition) System. I have thought to use a dc-dc flyback converter going from 12v, can also be 24v, to 400v. The discharge will be happening when I press a trigger button, which is why I am thinking of charge current, output current for the dc-dc converter, of 10mA.
I have not been able to come with the correct design for this project. Could anyone give me some tips or hints on how to solve this?
Edit: The idea, for now, was using this transformer: Myrra 94094. But thanks to some of your answers, it doesn't look to be the best idea.
