Can a 220/12v step down transformer used as a step up transformer? explain me ?

NOt necessarily 12v any step down t/f whether it can be used as step up t/f by just reversing ?


Answers:    Transformers as a moment ago coils of wire around a metal core. They are not directional and using them within either direction is no problem. The windings ratio determines the voltage. For example, if the ratio is 10:1 you achieve one tenth of the input voltage out as you put in, minus some small core losses. By reversing the transformer you hold a 1:10 transformer and will get ten times the voltage out that you put within, again minus core loses. There is a current issue in this. In a step down transformer you can increase the current out over the current contained by. In a step up transformer, the current out will be less than the current surrounded by. The amount of current depends on wire gage and core size.

Yes its possible.For 220/12V step-down transformer,u should use 12A.C. (alternating current) at its output or inferior winding.For generate 12V A.C., u must use 12V D.C. to A.C. inverter.


WARNING:Never try to feed D.C. to the transformer as it will lead to short circuit & may even harm you.
