Cockcroft–Walton Voltage Multiplier Simulation on Proteus
CW multiplier is basically consists of n stages of a voltage doubler. A n stages CW
converts Vpp (peak to peak) source voltage into n*Vpp or 2*n*Vp. Using only diodes
and capacitors and cascading basic block, we can convert small AC voltage into high
DC voltage. So a N stage CW voltage multiplier converts input with following way.
First of all let's analyse it fundamental building block to understand how it works.
Here source is connected to a capacitor and a diode in parallel with reverse bias
condition then there is another diode in forward bias configuration and then there is
another capacitor. This Circuit Works in a following way.
In fist cycle of the input, _Vp, Capacitor C1 is fully charged with diode D1. Then in positive
cycle this capacitor charged up to 2Vp. Then capacitor C5 charged with diode D2 upto 2Vmax
and in next stage whole cycle repeated it self.
