Yes, that should have been 3V not 4V.
Bob Clark
Correction: with the usual circuit adding another stage takes it from
2V to 3V, not 4V.Bob Clark
Google didn't pull that one up, since Google doesn't archive binaries. Do you have another source for that?
Bob Clark
Use a good news server. Doesn't your ISP have a news server?
I designed it ;-) It's now on the S.E.D/Schematics page of my website.

How many times does it multiply the input voltage?
Bob Clark
"ChargePump-4X-Example.pdf" 4X ?:-)

This thread is setting some sort of record for "least coherent."

Why must you behave in such a boorish and rude fashion? "Wrong" is a fair comment. "Silly" is an insult. I have been around for a while and I have never seen the specific configuration we were discussing (A Cockroft-Walton multiplier that drives an inverter that drives a second Cockroft-Walton multiplier). I have seen many different kinds of voltage multipliers and have never seen that particular configuration ever used.You claim that that particular configuration is used, which was a surprise to me. There is nothing "silly" about not knowing about a particular rarely-used configuration.
People sometimes make mistakes. I appear to have done so out of lack of knowledge in this case, and I acknowledged my error as soon as I saw your post claiming that the configuration in question is indeed used, without commenting on your use of the term "silly." Seeing that I didn't rise to the bait, you repeated it after I said that I was wrong. What is the point in being a flaming asshole, Winfield? Why turn what could be a learning experience into an adversarial relationship? Do you really think that flaming a well-meaning person who made an error and then acknowledged it is acceptable behavior?
I think you are a better person than the one I am seeing in your posts.
Multiplication by an integer is equivalent to adding an integer number of times. The "multiplier" terminology refers to adding n times where n is the number of CW stages- the output is n*Vin.
Nope- the second stage produces 3V and not 4V. The 10 stages gets 11V and not 20V- each stage increments by 1V.
Doesn't seem that anyone has hit on that method yet.
What's the puzzle? The ac swing you have available to work with and stack up, is always V, that's not doubled, or tripled, etc., at any point. That'd be nice, but how would it be?

This is true. Rational people could explain the OP's issue using the terms "AC" and "DC," but we can't use those terms here anymore..............................
well i meant to say 3000 V not 3000 Kv or should have said 3Kv on the input. and that is on the input side of the pie xformer. the output of the pie is around 12k..18k volts. one of the vessels is around some where in the neighborhood of
40 or so feet long.-- Real Programmers Do things like this. http://webpages.charter.net/jamie_5
from what i have seen in here from some, it may not be an accident! :)

Cockroft-Walker multipliers with fewer components can multiply voltage
8 times:Cockroft Walton Voltage Multipliers
Are saying your circuit has the advantage of being able to be staged to *multiply* by 4 each time?
Bob Clark
"Charge pump" is a catch-all term that is also applied to Cockroft-Walton multipliers. Are you sure the type you're thinking of can be staged to *multiply* by the same factor at each stage?
Bob Clark
Read more carefully, it multiplies 8X the PEAK, or 4X the Peak-to-Peak; mine does the same, just in a fashion that allows monolithic implementation without forward biasing wells and creating latch-up, etc.
Diodes can't be implemented in monolithic form, as in your example, because all kinds of bad parasitic things happen.
You've got a hair up your butt about "staged".
"Staged" doesn't happen. The output is DC. The only way would be to add a switching device at the end of a 4X and you have no power to run it.

You can't read what is not there. You ONLY said it multiplies "4 times". The Cockroft-Walton circuit page specifically says 8 times peak. You're post is also misleading in that it was in response to the post by "cnctut" who suggested "charge pumps" could multiply at each additional stage. I don't know if this is accurate or not.
Bob Clark
No charge pump MULTIPLIES! A better phrase would be STACKER... stacks one capacitor on top of another.
