Answer Posted / sanket patil
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.
