Answer / nikhil patil

dc transformer is nothing but of dc chopper.chopper works
as dc transformer.it can be used for step up &step down of
dc voltage.

Answer / smartboy123

IT IS IMPOSSIBLE TO CONSTRUCT DC TRANSFORMER.
TRASFORMER IS WORKING ON MUTUAL INDUCTION PHENOMINA

Answer / sanjeev kumar

transformer works on the principle of mutual induction and
it is immpossible to produce varing flux by dc. hence dc
transformer does not exist.

Answer / krishna

Bull-Shit!! What DC Transformer????
There is no such thing in the world....
Transformer is a thing which works on a principle of Mutual
Induction which requires Frequency.
In DC power there is no frequency at all,
so, where is the matter of DC Transformer?

Answer / gunnam santosh

if connect dc supply to a transformer temperature will be
increased and it gets damaged

Answer / brd ganesh

T/f works based on mutual induction.so if we r
give dc to that it will burn (after saturation) due
to no oposition(eb=0). Although it act like normal t/
f at starting instant. So bye using t/f we can
change ac voltage w.r.t currunt. To change dc
voltage we can use choppers.

Answer / denzel101

You must be refering to a dc converter whereby a dc voltage
is stepped from one level to another.

I believe the poster is thinking of transformer in an ac
circuit and compare it to the device that does the same in
the dc circuits. I must say I haven't heared of a dc
transformer though.It must be wrong terminology.

Answer / michael

Dc transformer is possible to construct but you need
additional circuit for it to work. you need a high speed
switching component for the dc to form into a AC look alike
voltage. then since the dc voltage becomes like an ac it can
create a induced voltage on the secondary winding of a dc
transformer.

Answer / ant

transformer is a static device that works with the principle of induction. since induction an ac phenomenen,transformer can not be dc.

Answer / saad

there is no dc transformer
