Volts, amps and electric power supplies/components

[John Rumm]

Well you see, the reason many people describe such circuits as doublers, is because you stick in an AC signal with a peak voltage of V in, and you get out DC at 2V. This is contrary to the usual behaviour of a linear unregulated supply where it will have a no load voltage output of only V.

You can find similar circuits that can give triple or greater multiples too.

Do a web search for "voltage doubler", and you will find many circuits like that which you describe.

Now why everyone is throwing toys out of the pram over the precise naming of these circuits escapes me, since its bleeding obvious that while "voltage doubler" is indeed in very common use, there are different names and terminologies commonly in use as well.

A dubious claim IMHO, but not relevant, so let's skip that.

Yes, and calling it a doubler is also perfectly acceptable.

However don't take my word for it, see fig 1.78 and following explanation:

So, what does 'cascode' imply to you?

Or 'Darlington'..?

Or 'Buck regulator'?

[John Rumm]

Its the fact that it makes use of both positive and negative halves of the waveform, that makes it a full wave rectifier.

A constant current source and a current limit are two differnt things. Not sure how or where sample and hold comes in to it as the key here seems to be to use passive devices rather than active.

You seem to having difficulties again. I'll cross post this to a more appropriate group; hopefully someone there will have the fortitude to assist you with these definitions.

[The Natural Philosopher]

y do you knowitall trolls always change the subject when someone is about to prove you wrong?

I know perfectly well what they are. The point is that what they are is absolutely NOT '*implies a certain mode of operation*'.

[Julian Barnes]

Oh dear. Sounds like someone's been on the gin again. ;->

We seem to have got ourselves a new troll :/ He's acting the idiot in s.e.d as well.

You're not coming over as being very bright.

With just the one rectifier, would you be the sort of person to call this circuit a "voltage halfer"?

[Cursitor Doom]

He's clearly never heard of the proverb, "when you're in a hole, stop digging."

What are you trying to prove? Giving a partial description of a device and out of context as well doesn't prove a point. There are hundreds of terms that you can do this with such as Foster (seeley discriminator);Black (level clamping);Line (flyback EHT) or Line (output level) . Doesn't prove anything.

Have you heard the one about the man who bought two 9v batteries and connected them in series to make a voltage doubler?

[Tough Guy no. 1265]

Mathematically yes, but try grabbing a live wire that has an average of zero....

[Tough Guy no. 1265]

Yip, take a bridge rectifier, like this:

But split the connections at the top and bottom of the bridge so the diodes are no longer connected together. One halfwave charges one capacitor, one half charges the other, now connect the capacitors in series.

[Cursitor Doom]

Did it work? ;->
