Yes, I know how they work. Are you sure they are going to work in your application?The specific voltage multiplier I am looking at is a Half-wave Voltage
Doubler, or more accurately, two of them.
Here is the general description of Voltage Multipliers from the Electrical
Engineering Training series: http://tpub.com/neets/book7/27m.htm
Gee, thanks markilsley@dodo.com.au, you really are a vindictive prick.It is TWO Half-wave Voltage Doublers. I have Emailed the schematic to
gswan3@bigpond.com.au in pdf format. I can't think of any easy way to
publish it here. Enjoy the Spam.
I've no idea, maybe you could enlighten us?p.s. What does a wolf in sheep's clothing do over the Easter break?

As Phil mentioned, and as your article also mentions:
"Also any small fluctuation of load impedance causes a large fluctuation
in the
output voltage of the multiplier. For this reason, voltage multipliers are
used
only in special applications where the load is constant and has a high
impedance
or where input voltage stability is not critical."
Will the input to your regulators always be above 17VDC for all load
conditions
of your application?

OK. Once you have done that the picture will be clearer. See if you can measureWill the input to my regulators always be above 17VDC for all load
conditions of my application? Yes, I believe so. Or at least close to that
mark.
I haven't been able to measure the input as yet. I go into town this Friday
to take my son in to hospital for his weekly physio session, I'll try to buy
a small set of alligator clips for my DMM from Dickie Smiths at that time.
The chances of shorting across any two of the Regs pins (with the power ON)
whilst probing amongst numerous obstacles is perilous and I won't do it
without the clips.

Wonderful! - But how does that help you get your regulated 9VACI'd disagree with it, only because what you speak isn't true.
Here's one that sold on EBay for only $51.00, a few minutes ago:
http://cgi.ebay.com.au/LIEBERT-UPS-GXT700-Mini-Tower_W0QQitemZ230113036855
If you go to http://gxtwebdemo.liebert.com/ you can see from the simulation
of the GXT series UPS that it regulates, rectifies and inverts the output
24/7. The Bypass is only engaged during battery failure or replacement.
Yup, I'd say that qualifies. Online and near perfect sine wave output.
I would have bid but I don't feel like a drive up to Sydney to get it.
With a bit of patience I'll pick one up for even less. Fact.

top postings are rarely clear.In this case, as indeed in ALL cases, the topography I chose would have made
ABSOLUTELY NO DIFFERENCE to Swanny's dilemma.
ALL my explainations would STILL appear BELOW this point, irrespective of
the internal topography of the individual postings.
Is that clear?
It might have gone to $55 or $60 if you had bid add shipping to thatI'd disagree with it, only because what you speak isn't true.

This is going to drag on for months, isn't it? :-( Maybe I'll check
back here in about August and see if any sanity has returned to this

Sorry, been away from this for a while - WTF are you talking about? Are youWhat utter, utter face saving piffle.
Every few months a FLOOD (dozens) of x-Govt UPS hits the EBay market,
driving the price down to the ground. A USED, sine wave output, online UPS
is CHEAP AS CHIPS because SUPPLY EXCEEDS DEMAND for them. Business and
Govt.
Departments won't buy a used UPS.
The fact of the matter is that Online, sine wave output, UPS regularly
sell
on EBay for ABOUT that price. In an AUCTION the price can go UP or DOWN
dependant only on supply and demand at that TIME.
Even if you are unlucky enough to buy one with dud batteries, they are
literally STUFFED with high value salvage parts.
