What will happen if I apply DC to AC transformer? please
send detailed answer at habib_rahman_habib786@yahoo.com
Answer Posted / glen saldanha
it depend whether it is dc pulsating or pure dc waveform
as transformer is a reacive load whose formula is
Xl=2phi f L
In pure dc the frequency is zero so it is as good as a
short circuit but in case of pulsating dc as frequency is
known it will definately produce a dc pulsating at the
secondary of the transformer output.Example in SMPS of your
computer these transformer are used.

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
