Dear Mr Akialok,
I think, the answer what you have given is not completely
right.As the VA ratting is not going to change in the
transformer, the max current in primmary & secondary will
remain same in whatever way you use.
For example: For 1 KVA 220 V to 110 V trafo, Max primary
current I1=1000/220 = 4.55 A & Max Seconday current
I2=1000/110 = 9.09 A.
So even if you reverse the source voltage, in any way you
can not use for more power.
Please reply for clarification.
