What is the real output of this circuit and why? It's name is voltage doubler but I connect it to 230V AC and tested output with a multimeter it shows 640 V DC, is it really output 640 V DC? why? and how can I made a doubler with 440 or 450 V DC out? I can not use transformer for some reasons.
also I have a 500 V 1200 uF cap that I want to charge it only with 450 V 1200 uF (120 J), what happens if I connect that cap to this doubler? Does it charge to 500 volts (150 J)? how can I charge a 500v 1200 uF cap to only 450V?
