Sources for high voltage power supplies?

[Michael Noone]

Hi - I need to find a high voltage power supply. I'm not quite sure yet
exactly - but It'll need to be something like +- 400-1000 V DC (I haven't
been given exact specs for what's needed yet) and about 150 or more watts.
Any suggestions as to what I should get? Thanks,

Michael J. Noone

This type of power supply is usually custom made for a specific use.
Does your 'group' include any engineers?

I can't find ANY high dc voltage power supplies. My normal electronics
distributors don't list anything above about 60V, at least that I can
find.
Hence the title of my post "Sources for high voltage power supplies?". I'm
looking for a manufacturer that makes high voltage DC power supplies, or a
distributor that sells them.

Are you some sort of Chemist/Biologist or are you dealing with such things?
Why don't you toddle off to the electronics department of your university
and ask them.

Ain't supporting academic scientists interestin'? One will come in with
a complete set of goals and spec's...and the next one doesn't even know
what they want. But, at least I never have to ask: "Would you like
fries with that?".

First question I start with is: "What are you doing?" (In a pleasent,
inquiring tone!). I find that this is important whether it's the
professor with all the details, or the one who doesn't know where to
start. Then, see if the details fit the request, or build a set of
spec's for the clueless.

My best tool is, with my "helpful" questioning, to let them come up with
all the spec's. I frequently find that they are trying to do what has
already been done, by someone else. And, a little research will give me
the answers, or at least the right questions to put to my customers.

I still can't believe they pay me to do this job.



I don't know, I think being a technician for PhDs can be a very good
portion of your education...

While an undergraduate student, I worked as a technician in MIT's
Building 20 supporting PhDs doing MHD research.

Figuring out how to understand them and build what they _really_
needed certainly helps me to understand customer's needs today ;-)

...Jim Thompson

Jim,

I'm 59, with many jobs behind me, and they still pay me to play.

I've only had two jobs in my life that I really hated. One was, when I was
young, on the farm. My brother and I worked for a neighbor picking up
"small", round, hay bails by hand. We did this all the time for all of our
neighbors and relatives. The farmer was the type that thought it was better
if he could pack all the hay into a bail that the bailer could spin.
Needless to say, they were 100 to 200 Lbs each. The first night we came
home, whining and complaining about it at supper. Dad just said: "If you
don't want to do the work, don't take the money". We went back the next day
only because we had committed to it, and he was a neighbor. But never
again. The second, was "one day" with a driveway cement crew, when I was in
college.

I've worked many physically and mentally hard jobs, but only if I was
willing to take the money without complaint. I've always sought out jobs
that let me learn, play, and solve problems. Getting paid always seem
seconday, but I've always seemed to find places that were eager to pay for
that. I have friends, who make a great deal more money than me, but they
complain constantly about their work or workplace. They seem the justify it
by saying that they need to work as they do, to make the money, so they can
do the things the want when they aren't at work. I sometimes want to quote
Dr Phil and say: "Hows that working for you?".

I think I remember this from a couple of weeks ago - you're saddled
with a pack of PHDs who have no clue what they're looking for, so they
expect you to come up with a universal supply so they can try
_everything_ and see which end their of their ass has a hole in it.

Find the most expensive +800-0--800 supply you can find, double the
price, and quote _that_ figure to your bosses. Pocket the difference.

Good Luck!

I searched Google with the exact same terms, except with a couple
quotation marks. Problem I've been having is that all of the high
voltage power supplies I've been able to find are either A. low power
(under 50W), or B. perfect, but really expensive ( >1K USD).

Your memory serves you perfectly - same group. Normally the students I
work for/with are difficult to work with - but eventually I can always
force them to make up their minds. But this time it's even worse - I'm
doing this for a group of 2 professors and a number of grad students. We
have a weekly meeting - and after every meeting they decided on entirely
new specs. I mean they completely redesign everything every single damn
week. Those of us working with them are either about to go A. insane or
B. homicidal. (or perhaps a little of both). They seemed to think that
we could use our large variety of 24V DC power supplies for this task -
that somehow I could work some magic and turn +-24V DC into +-800 (or
whatever they want any given week) - and though I suppose this is
possible - I must admit that it is completely beyond my skillset.

Something with some magic molecules. Yes - THEY (being a group of

apply very high DC voltages to some special fluids of "magic molecules" at
various points and some other nonsense which hasn't been explained to me.

Every week I prod them till they give me exact specs. Then the next week -
suddenly they decide that they were wrong and give me new specs - over and

At the possible risk of sounding silly...

How about 66 12V batteries?
Sealed lead acid cells are rechargable, aren't terribly expensive and can
deliver fairly high currents when it is required. Output voltage can be
adjusted by adding and removing batteries (66 step adjustment!).

If you don't bugger me about then I could knock together a scalable design
for you. We'll both learn something. I'll do the schematics and boards along
with documentation. You get to buy the bits, wind the magnetics and build
it.

You could make one for less than $1k if you used toobs and a mains

hehe good call there.

If they are changing their minds every week, what is the real pressure
on you to provide something? Could someone be winding you up?

They're pretty irritated with me that I haven't gotten their "plan"
implemented yet, even though they just changed what they wanted AGAIN
last Wednesday.

You could report that you considered connecting 34 off +/-24 V power
supplies in series, but the transformer insulation wouldn't hold up,
and
see if anyone laughs.

I have yet to hear any of them laugh... Very serious crowd. Just out of
curiosity - why wouldn't the transformer insulation hold up? Not that I
have 34 24V power supplies lying around... (though I bet I do have about
10 or so)

Heh ok. No hard feelings. I agree about Bloggs though - I have gotten

I really did google before coming here - the problem is everything I could
