Hi, advice needed
i got a question
1.
How to connect transformer 27vac - 0 - 27vac to get 54vac - 0
is there alright if i connect 27vac & 27vac (than i get to 54vac) ?
or there is a better way ?
2.
from this single transformer ( after i get 54v - 0 )
i want to connect with to 2 psu.
can i use 2 bridge rectrifier there
can i connect like this (below) ?
or there is a better way ?
................. + ................................. + .................
0.....~ ........1..........~ ------ ~ ..........2.........~ ...54
..................-....................................-..................
or i must connect like this
................. + ................................. + .................
27....~.........1..........~ ------ ~ ..........2.........~...27
..................-....................................-..................
1 = First bridge rectrifier
2 = second bridge rectrifier
----- = jumper the bridge rectrifier
i really dont know bout this
please help me

No, there is only one way to do it.or there is a better way ?
None of your drawings will work. The rectifiers must be in parallel on the AC side, not in series.from this single transformer ( after i get 54v - 0 )

If you want to get 2 separate DC circuits, 2 rectifiers have a slight theroretical advantage. In practice you won't notice much difference. If you want to connect the DC rails together again, the way it looks in your schematic, 1 rectifier is better.

Thanks for your advice pacific blue

i will connect 27v with 27v to get 54v
2
Yes i want to get 2 separate dc circuit
my friend use one rectrifier and get hummm
i will try like this
