Ok, next...

I need to know what can I say about these 2 in 1 circuit... It's a voltage multiplier, or whatever it's called! I guess is also known as something like Cockcroft-Walton multiplier...
What can be told theoretically about this two circuits where the diodes directions were inverted?
I've already read this article about the subject but honestly there were some details I haven't understood.

Morning Psy,
You have not said which details are giving you the problem.

Basically the 'doubler' , offsets/shifts [clamps] the negative half cycle from below zero volts, so the negative Vpeak is clamped at the 0V level.

Consider a sine wave of say 10Vpeak, thats +10Vpk swing then thru -10Vpk swing.

Now clamp the -10Vpk swing to 0V reference, this means the +10Vpk is offset/shifted up by a 10V, giving a +20Vpk.
[I am ignoring any losses due to the diodes]
