Circuit digram collection

While searching for information on a multiplier IC, I found this useful
collection of circuit diagrams:

The AD534 multiplier was used in this interesting circuit which provides
1000 volts at 300 watts.

I think it is used for a constant wattage output.

Fantastic! This solves the world's energy problems!
"it takes 300 mW and turns it into 1000 volts at 300 watts"

That's perpetual motion if I ever saw it, multiplying power by a factor
of 1000.

It's the magic (and very expensive) AD534 IC. And I have 30 of them! I'll
become rich and famous!

(actually I didn't notice that)

What, you've never heard of a "multiplying DAC" before?

The TY 93 is an obsolete transistor inverter xfmr
http://www.triadtransformers.com/ty73.html,
datasheet specs a 28V primary and 500V output at 250ma.

You can use an ordinary 50 watt toroid rated 120V to 6V at 50/60 Hz, and run
it backwards at 600 Hz to get 1200V out with a 60 VAC input, at 500 watts.
Most iron core transformers, especially toroids, can work up to at least 1
kHz. I have used toroid transformers to drive a special three phase motor
that I rewound from a single phase, using a VF motor controller. The motor
was rewound with much heavier wire so it was still nominally 1/2 HP at 60
Hz, 8 VAC, but I ran it up to about 240 Hz at which point it should be able
to supply 2 HP. And I only needed about 15 turns on the toroids.

Now that was a cool project...

"Care should be taken with this circuit because it takes 300 mW and turns
it into 1000 volts at 300 watts"

1000 times over unity?

Actually, according to Always Wrong Missing Prong, aka Hellequin, prefixes
are always capitalized, so that should read 300 MW. A bit inefficient, but
does not violate the laws of physics.

Who would want a variable regulated power output supply like
this other than maybe a component tester?

I once built something like this to drive a halogen arc lamp, which needed
constant wattage, but it never quite worked correctly, and the high voltage
got to the AD534 multiplier IC and fried it..

I've never heard of a multiplying DAC that amplifies power. I've never
heard of any electrical device that multiplies power. I'm more familiar
with the type that has an efficiency value less than 1. That's what
makes this device so wonderful!

This is called a "power amplifier". Of course, it does not multiply the power
of its own power supply.

OK, use one to multiply voltage and another to multiply current. ...but I
suppose the results would be in Craftsman watts. ;-)
