Microwave Transformer

[Jim Works]

Jim K.

I am new to electronics so please be gentle.

I have a microwave transformer from a 600 W oven. This is very confusing to
me because the power in side has the standard two lead connection. The part
that puzzles me is, the out side has three connections. Which connections
are the ones I should use? I am also going to give you all the info I have
off the top of the transformer.

Make of microwave oven is: Sharp Carousel 2

RTRN-B010MREO
120V 60HZ
TAN-100M
TABUCHI MEXICO
912464

I hope you can help me.

DANGER! WARNING! Microwave oven transformers make lethal voltages.
If you don't know what you are doing (and from the above, you don't),
please don't screw around with them.

Please learn a lot more about electronics!

AC Voltage goes in and there are two outputs. The magnetron is a vacuum
tube that has a filament that needs voltage. The common lug on the output
and the filament lug power this. The other lug and the common along with
a diode and capacitor voltage doubler create the 3000 Volts needed to
drive the magnetron to produce microwaves.

There are lethal voltages in a microwave. If you do not know much about
them you could die and your wife and children will cry and it would suck.

2 of three combinations are leathal. Get rid of it without ever applying

mains power. If you need to ask odds are it will kill you...

Use? For what? There are windings on the secondary for both the high
voltage and the filament, and they might be connected together
internally. See Sam's repairFAQ site for more info.

Do a control F and type in microwave or skip down to that topic.

a power supply, or something. If it's a 1 : 12 ratio, then it might put
out about 10VAC, at a few amps.

From what I've seen, the secondary is on the order of 2.5KV, so it's
more like 20:1, or maybe 6V output.

Yeah, some idiot warmed blood for a transfusion in a microwave, so
therefore microwaving food must be bad for you. Sigh.

Ah, science from someone who practices kinesiology, hooray!

Every one who has replied has advised of the lethal danger of these
things. If you knew a little more about High Voltage supply equipment
you would realise what danger you are in!

There are no domestic/hobby applications for such supplies except
for Ham Radio final amplifiers for which you will need to pass the
FCC examinations and hold a current licence of proficiency.

Dans Data had an article IIRC about making a small electric welding
set from the primary circuit as is and removing the HV secondary
altogether and adding a very heavy braided high current winding
instead.

Mains voltage circuits are dangerous enough at 115/230 VAC but
the several thousand volts on its secondary is very very dangerous.
If you get bitten by it you will remember it for life, should you survive
the encounter. HV electric shock burns out the core of fingers and
arms leaving a charred mess where arteries and veins and nerves
fibres used to be.

Kitchen microwaves operate at about 3,000 volts DC but that's boosted with
a voltage doubler. It's 1500 VAC. So 12 to 1 is a good bet.

The few that I've salvaged have a single diode, so it looks like it's a
half wave rectifier, but it isn't. The other rectifier is the magnetron
itself, so it's actually a V doubler. So I would venture to say that
the transformer is somewhere in the kV and a half range, but I'm
certainly not gonna put my DMM on it to find out, because it's rated for
750VAC max!

Umm, no, you don't, because you're still asking:

You can cut the leads off it, throw it in the trash, and live another
60+ years. Did you read the WWWebsites that say that you can draw an
arc off it a few inches away? That you can kill yourself without
actually touching it? Is there no-one who will miss you when you are
gone? I know all you teenagers are immortal, but let's not push our
luck, shall we?

Duh!!!

Excuse me everyone, but I don't anything about this explosive stuff I have.
I'm thinking of putting it on the fire to dispose of it.
Can anyone lend me a match....

Er, "If you do, please let us know" ??? HUH???

You believe in ghosts?

Maybe he should put a couple hot dogs across the secondary and apply
power, and watch them fry. Probably nearly explode from the heat and
steam.

The output side of the transformer can have multiple windings and
multiple tappings on those windings.

Now, what you have there is an extremely dangerous threat to your
continued existence on this planet! Please don't connect it to the
mains A/C supply since the output side has very high voltages which
can leap out and grab you - no, I'm not joking.

Leathal? Try lethal. I've read some interesting articles on projects
using microwave oven transformers, such as the spot welders and welders.
But they require that you rewind the secondary. Has anyone flipped the
transformer around and used it with the AC line connected to the HV
secondary? Obviously it's not going to put out as much power as the
normal way, but it should out out a substantial amount. Might work for
a power supply, or something. If it's a 1 : 12 ratio, then it might put
out about 10VAC, at a few amps.

Of course you might get a backache from carrying your power supply
around, but then that's another concern.. ;-)

Hand-waving and screeching and the proponents don't do their credibility
one bit of good. Wikipedia allows all to participate but the controversial
ones get their own category.

There is concern about unnatural products being produced but no good
evidence.

There is proven information about leaching toxic chemicals out of plastic
when heated in a microwave so use a good ceramic.

AFAIKT you only get radiolytic compounds in nuclear irradiated foods.
