Hi,

Does anyone have a 9V 1A transformer schematic? I want to
integrate it into a project to run a disk drive. The smaller the better.

Thanks.

The usual procedure, assuming you are using a CAD
tool, is to pull a generic transformer symbol from the
library already available with every such tool I've seen,
then edit some fields on it to state its output value and
current rating.

If you are drawing a schematic by hand, Google for
the phrase "transformer symbol" to see what it should
look like. Or buy an electronics drawing template.

Sorry, I guess I wasn;t clear. I need a schematic of a 9V 1A PSU.
Such as the transformer, capaciters, diode....
It's an AC to DC. Would like a 120V and 250V version. I'm building a
project and need to embed a PSU into the project. Hope this clarifies it.

Thanks.

Still not clear.
You want 9.0000VDC up to 1A from 90-264VAC?
It's very difficult to buy ONE EACH transformer of the types you want.
I expect you haven't considered the subtleties of the design...high
line, low line, efficiency, heat sinking, trough voltage...the list is
endless...schematic is trivial, but the details won't show there.
You're more likely to have to design around an available, non-optimal
transformer.

You're MUCh better off to buy a switcher wall wart to do the job. If
you only want one and you're cheap like me, I'd start looking for
cellphone chargers. Or laptop charger and change the voltage setting
resistor. If it has to be inside, it's still easier to break
it open and mount the board inside.

Now that you've clarified the fact that you need a power supply --
Click to expand...

How much better is smaller? If size really is paramount then you need
to make an off-line switcher, which isn't a trivial task. If you can
get away with 6-10 cubic inches (about 2/3 of a cup) then you should be
able to do the transformer -> rectifier thing.

Does it need to be regulated? If so then you need a transformer ->
rectifier -> regulator.

Look around on the web for "power supplies" -- that's really what you
want. Or go get the latest ARRL handbook, which will have lots of
examples and "how to" information.

LMAO!!!! Larry gave a very direct answer to the OP's question. He
specifically asked for a schematic for a transformer.
It was all very tongue-in-cheek. I thought about giving a very similar
answer but Larry beat me to it.

All that said, the OP still hasn't given enough info to give him a
definitive answer to his needs.
Lacking are such details as...
Is regulation required?
What are the allowable ripple/noise?
Does he need a PSU that can be easily switched between 120/240 mains
voltages, or is a single mains rated input sufficient?
What are his size limits for the unit?
etc., etc.

LMAO!!!!

Still not a clue.
This power supply doesn't say if it's regulated. Look at their list of
power supplies. Some say they're regulated, this one doesn't. Does
that mean it isn't? Or just forgot to put it? NO SPECIFICATIONS LISTED.

If this unspecified power supply meets your needs, you're probably not
gonna find a transformer smaller than the one in there. Bust it open
and use the parts.

The schematic for what you want is trivial. Transformer feeds diode
bridge or two diodes, depending whether you have a center-tapped
transformer, into a capacitor. Now all you need to do if figure out how
much ripple and min/max voltages you can stand. Then you need to buy
a transformer that does that...and you probably won't find one.

So, we're full circle. Go buy the wart and take it apart. Then instead
of having a well protected wall wart supply, you'll have AC running
around in your project, shock hazard, fire hazard....there's a reason
most products today use wall warts.

The simplicity of the answer is inversely proportional to the simplicity

Thanks,

I have found this schematic online (not schematic symbol)
and I think I could adapt it to supply a generic/home electronics 9 volts I
need to
run a generic floppy drive. I'll also be checking out that book you
mentioned for
future references. http://www.bonavolta.ch/hobby/en/audio/reg_sup.htm

Thanks for your help.

BTW, I did ask for a transformer schematic:

NOT a transformer schematic symbol:
http://images.google.com/images?hl=en&lr=&q=schematic+symbol+transformer
as some were confused. Sorry about that.

Oh, woeful am I to have failed in your eyes, master.
Ever hoping to gain your approval, but still ignorant

To the OP: Please be patient with my efforts to
please the infinitely exaltable Fred Bloggs. He sets
such an inimitably high standard by example with
his wise and kind posts that others can hope for
only the most excrescential results in comparison.

I believe that Larry was attempting to parody Fred's style. Don't take it
personally. I don't think Larry meant any of that stuff.

If you use google to search on Fred's responses to posts, you will see
that sometime he does insult people without providing any constructive
advice.

It seems that some people really annoy Fred, and Fred let's his
annoyance show. But he does seem to know what he is talking about when he
talks electronics.

As far as I can see, that is clearly an
overstatement. Fred can make inane
mistakes, like anybody else, but does
so by plunging into certain subjects
about which he knows very little with
an air of authority. And when he is
shown to be wrong, he is rarely willing
to help resolve the ensuing confusion
for the sake of both his credibility and
the OP or other participants.

If you doubt this, I can provide several
recent examples that should suffice to
convince any independent expert.

If you are merely being kind, trying to say
"he often knows ...", I am inclined to agree.
But you do non-experts a disservice by
promoting Fred to the status of "authority".

I've known a small number of people who
would merit such exaltation, but Fred is
most certainly nowhere close to that. To
be an authority worthy of relying upon, a
person must not only know a lot; they
must know what they know and what
they do not know and be honest about it.
Fred completely fails to understand that,
being more interested in ego maintenance
than helping participants discover what
they need to know to resolve their issues.

I'm not an expert on power supplies, but this one shouldn't be too hard if
it is just for some kind of home project or whatever.

Note that if you are designing a real power supply for a real product that
has to get regulatory approval, then you may need expert advice.

The simplest way to build a power supply is to just use a transformer
(put a fuse or two on the AC side of it), a bridge rectifier, some
capacitors, and an LM317 (or something similar) with a big heatsink, and
maybe another capacitor at the output.

Choosing the transformer voltage is a bit tricky. If it is too low, then
the regulator will drop out of regulation and the output will ripple. If
it is too high, then the regulator will dissipate too much power, and
overheat. You might try a nominal 12 Volt transformer for a 9 Volt
regulator.

Choosing capacitor values is a bit tricky, too. The bigger they are, the
more they force the transformer into a low duty-cycle, high-current mode
of operation. But if you don't have enough capacitor, then the Voltage
will dip too low during the low part of the cycle, and the regulator will
drop out.

Have fun.

In fact, the overall efficiency, measured as Idc/Irms, is higher at low
rectifier conduction angles, even though the peak diode current is
higher. A large filter capacitor doesn't increase transformer heating.

Here's an idea: buy 12 volt xformer with no center tap. Connect to it a
small bridge diode rectifier rated for 2 amps or higher, and to that a
large value capacitor such as 470 uF or greater rated up to 35 volts or
higher. Follow that by a 9 volt regulator such as the LM7905 voltage
regulator chip (may need a heat sink for that). The whole thing will
take up very little space but will give you about 9.1 volts DC with
pretty fair regulation and low ripple. This is pretty much basic,
Electronics 101, kind of stuff.

I thought Larry was just f'ing with you in his first response, but
he admitted otherwise. I figured that by asking for a trans shem,
you meant PSU, but couldn't help but marvel that someone *might*
actually want a trans schem (not symbol) as if they needed a schem
to build one. It's like asking for a shematic of a wire to
understand its operation or to make one.

I recently saw those two butt heads - oops! Let me rephrase that ( I
gotta leave it in cause it was a funny mistake ) - "those two argue"
and *both* were right - that statement made without me going back to
nitpick little points that may have been incorrect, misworded,
whatever. It's more like they discussed 2 different approaches and
it was more a matter of their respective EE philosophies.

I've read more of Fred's EE info than Larry's and I haven't found
any flaws.

You changed the subject line twice and I had to check google to
verify continuity (no lost posts) Bad!!!

You should have posted to s.e.basics (seb) or
alt.binaries.schematics.electronic (abse) and didn't. Bad!!!

I asked someone earlier today... "Is the google server down?"
There's more friggin' PSU info and schems out there than I can shake

The usual procedure, assuming you are using a CAD tool, is to
pull a generic transformer symbol from the library already

Damn you're dumber than a rock- no clue in hell what the OP was
talking about...



LMAO!!!! Larry gave a very direct answer to the OP's question. He
specifically asked for a schematic for a transformer. It was all
very tongue-in-cheek. I thought about giving a very similar answer
but Larry beat me to it.

Looks like you're the one behind the curve. You seem to miss the point
that his answer was of about the same characteristic relevance as all
his other posts- he is a totally clueless nitwit, and any attempt at
humor would be swamped by the overwhelming hot air, pretense,
pseudo-theoretical factoid trash, and other elements of his style.

Hey, loudmouth windbag, where are all the words on the noise induced
detection problem in the 40khz amplifier thread? Your days of skulking
off are over- and we are calling you due, pussy, phony, illiterate trash
heap boy. Looks like you ran out of elementary factoid braindead
arithmetic trash and now you are be called on it- You just don't seem to
be taking up the challenge, mainly because you have run out of material-
not so verbose when you have to actually produce something tangible are
you, punk programmer, pseudo-intellectual, and pretentious fraud that
you are....like I say, you are a drowning rodent.
