My voltage doubler - is this works?

This is my voltage doubler:

I don't know much about this field. It just came from my imagination.
But, in practice, can this circuit works?
Whatever it's -25v/0v/+25v or 0v/25v/50v.

Don't build and test it unless you have lots of spare diodes.
In other words, it won't work.
Follow the current path.

Sigh...
Trace out your diodes - there are a pair of 2-diode short circuits across the AC input, in opposite directions. All you are doing is doubling the amount of blue smoke and brown smell.

Oops - Sofaspud got there first

Like this?

An externally hosted image should be here but it was not working when we last tested it.

 

[sofaspud]

That works. See how each half-cycle charges a capacitor to the secondary voltage? Net result is 2Vin across both caps.

 

[moses1202]

How about this?

An externally hosted image should be here but it was not working when we last tested it.

 

[TonyTecson]

you must have thousand upon thousands of diodes to fry....

 

[sofaspud]

Put that circuit in the round file and forget about it.
