Understanding Vout Waveform and Voltage Ripple in Voltage Multiplier Circuits

[sean23]

I am trying to simulate a voltage multiplier circuit on Pspice simulation package, which will produce an output voltage Vout.

What is the waveform of Vout supposed to look like?
And also how will i work out the voltage ripple of the waveform?

Info ??

Sean you have not given enough info here -- I assume you mean a dc to dc multiplier but there is more than one way of doing this and the results differ.

If your talking about a Cockroft Walton voltage multiplier then you put AC in and get DC out. I simulated this in Electronic workbench and used the o-scope to measure ripple, use AC coupling. The amount of ripple depends on a bunch of things, check out this website http://home.earthlink.net/~jimlux/hv/cw1.htm

cockroft walton voltage multiplier

yes it is the cockroft walton multiplier circuit, putting in an ac source and producing dc.

i have an output waveform but i cannot work out the voltage ripple

cheers guys

hey random question about voltage multipliers (im only posting here because ppl have responded to this as is...lol) although they increase voltage they also decrease current, correct?

Yes. It's sort like a transformer. The power in can't be less than the power out (on a continuous basis). Since P = V*I, the output current must decrease in proportion with the voltage increase.

k, just makin sure. lol
