Why don't you use a vacuum tube rectifier ?? !!
I am thinking but when you saying "cancels negative pulses", It is don seem to be possible without non linear devices.....

Hi i think I got Idea, The core of the Transformer is a non linear device so it is possible to rectify only with transformers but it is some more tedious process...
Yes I do, still not found the polarities.....

Hi this is called as ,magnetic half wave amplifiers It is found in the lot of websites and you can also refer the exact design.........
A saturable inductor with DC bias can be used to cut signal halfwaves similar to a rectifier. But why would you do it?
Are you talking about a principle concept or a real design?
It seems so, according to post #4. A transfomer operating in the non-linear region could theoretically do the job. Unless another transformer way exists, something that uses special windings in phase and out of phase, to cut-off negative pulses.In simple words, you need a non-linear element, either a semiconductor or a saturated core.
That's more than theoretical. The problem is about design effort and performance.A transfomer operating in the non-linear region could theoretically do the job.
This can be safely excluded. A non-linear operation can't be performed by any combination of linear circuit elements.Unless another transformer way exists, something that uses special windings in phase and out of phase, to cut-off negative pulses.
Hi what FvM said is purely true and you can't cancel only negative pulses with any kind of winding connections... the only possibility is using a saturable core, for your more exact operation you have to choose a core which is more linear before it saturates, so that will give you un affected +ve pulse and no negative pulse.....
the circuit in #4 is
The core will be +ve ly saturated and If you apply a positive pulse there will be no more increase in flux so the primary is no more inductor and just a wire so it short circircuits and gives you 0 Volt..
But when giving negative voltage The flux reduces and the transformer acts as a inductor and drops the voltage to be on the output....
another thing is the source shd be a current source because if its a voltage source it will give some extra current when the flux is reducing and it will make it neutral effect...
and sorry for giving the circuit with diode and i didnt noticed..
