WHAT IS THE FUNCTION OF PULSE TRANSFORMER IN DC DRIVE
Answer Posted / syed shoeb ullah hussaini
first let me tell you about
transformer .. Transformer
work when an alternating
current is given as input ..... So
in the case of dc drive we
need an transformer but we
are have dc as a input ... In this
case we give input to
transformer in pulsating
form ... Means we are give
voltage in the form of pulses
so that transformer will work
but if we give direct d.c then
transformer will burn ...

when ac current flows thru d coil of a contactr,it energizes,magnetic field attracts d contact of the coil...nw wont dt ac current in d contct induce current back on to d coil thru mutual inductance leading to high currnt in d coil
