Adjustable Cockroft-Walton Voltage Multiplier 1
This one is a simple voltage double with a "clipper" (Zener diodes D6, D7). The clipper limits the peak voltage of the AC input voltage.
Adjustable Cockroft-Walton Voltage Multiplier 2
This schematic speaks almost for itself:
Input is any available AC source. The AC is clipped with the zener diodes D6, D7 and then fed to a regular Cockroft-Walton
multiplier. Take care of the right power rating of the resistors and zener diodes.
And if you have loads of Zeners around, you can even replace the regular diodes of a CW with Zeners.
Adjustable Cockroft-Walton Voltage Multiplier 3
Here we have a schematic for an adjustable cockroft-walton voltage multiplier to
produce a fixed high voltage. If the output voltage of the cockroft-walton voltage multiplier
gets above the zener voltage, the transistor switches on and the output of the CW multiplier
is loaded with the 10M resistor, so the voltage drops until the zener diode blocks again.
There is also a low pass RC filter to reduce ripple. The input voltage is mains (220VAC).
Connection 16 is the output.

Be very careful when handling high voltages!
