Guys, I'm concerned about two rectification circuits.
Attached you will find a picture of the two circuits.
The first is a classic half-wave rectifier.
The second uses two anti parallel diodes.
My assumption was that each of the antiparallel diodes would act independently as half-wave rectifiers producing on its ones terminals (Va and Vb) a DC voltage that is equal in magnitude to the 1/√2 DC voltage of the the diode in the first circuit.
However, after simulations it turned it's not the case....
It rather seemed that the voltages were 1/2 of the half-rectifier DC voltage.
P.S. I would expect a 1/2 ratio if the diodes were parallel. But why does it happen now???
My intuition says that one of the diodes should be rectifying the first phase (+) and the other the second phase (-). Therefore the wave selects each time the appropriate path/diode depending on the polarity.
I would be glad to hear some ideas on this.
Thank you.
