if the freequency is high we will get same square wave with
modified magnitude but if the freqcency is low impulse will
appiare

  Re: WHAT HAPPENS WHEN SQUARE PULSE IS GIVEN TO THE INPUT OF THE TRANSFORMER
Answer
# 5
IN SOME CASES THE TRANSFORMER IS DESIGNED TO APPLY DC
PULSE( NOT CONTINUOUS DC SIGNAL ) TO ITS PRIMARY WINDING
AND THE TRANSFORMER IS CALLED AS "PULSE TRANSFORMER".
IF DC VOLTAGE IS GIVEN TO WDG; AS WDS IS AS GOOD AS
INDUCTOR HENCE CURRENT I=(1/L)*INTEGRAL(Vdc)dt, WHICH WILL
CONTINUOUSLY INCREASE THE CURRENT FLOWING THROUGH THE
WINDING. HENCE THE WIDTH OF THE PULSE SHOULD BE SMALL
OTHERWISE THE TRANSFORMER WINDING WILL BURN.
IN THE PULSE TRANSFORMERS THE RESISTANCE OF THE WINDING
SHOULD BE KEPT MINIMUM TO LINIT THE I^2*R LOSSES AND LIMIT
THE TEMP OF THE WINDING BEFORE INSULATION FAILURE.

Answer
# 6
In Transformer secondary the emf induced depends on the
rate of change of flux,If square pulse or pulsating DC is
given thn output will be triangular wave(due to inductnce
of secondary)

Answer
# 8
It depends on the width of pulse,otherwise transformer will
go in saturation.also at secondary the pulse will not be
simple pulse but it will be rather impulse.

  Re: WHAT HAPPENS WHEN SQUARE PULSE IS GIVEN TO THE INPUT OF THE TRANSFORMER
Answer
# 9
Induced voltage=4.44*f*N*A*B = 4*form factor*f*N*A*B
f=freq
N=no of primary turns
A=area of wdg
B=max flux density

For sinusoidal input, form factor= 1.1 , its a peaky wave
form

But for square ac input signal, form factor is less than
1.1. (as its non peaky)

So other factors remaining same, induced voltage decreases
for square input ac signal.

Answer
# 10
if it is current input than answer is triangular voltage

if input is voltage than output is pulse but may not be a
square but out of phase
