A pulse transformer is optimized to transmit rectangular electrical pulses with fast rise and fall times at a constant amplitude. Pulse transformers are commonly used in radar, television, and digital computers to handle voltage and current pulses. There are two main types - signal pulse transformers for digital circuits and telecommunication, and power pulse transformers to isolate power circuits from control circuits. Pulse transformers efficiently isolate and protect control circuits while taking up small space due to their high frequency operation.

2. A pulse transformer is a transfor that is optimized
for transmitting rectangular electrical pulse (i.e.
pulse with fast and fall time with constant
amplitude).
OR
The transformer which handle voltage and current
in the form of pulses are called pulse
transformer . The use of such
transformer is quite common in radar ,
television , digital computer.

3.  For changing the amplitude of a voltage pulse
 For inverting the polarity of a pulse
 For affecting the isolation between source and load
 For coupling different stage of pulse amplifier.

4. There are generally two types of pulse transformer they
are :-
1) SIGNAL PULSE TRANSFORMER
2) POWER PULSE TRANSFORMER
Another type of pulse transformer is their high voltage
pulse transformer. This different transformer are
used in digital logic , telecommunication to
interface control circuit and power circuit.

7. The input voltage to pulse transformer is of discontinuous
nature . The most important requirement of these
transformer is that input pulse at the primary should be
reproduced as accurately at its secondary terminal shown a
square wave pulse at the input terminal.
The pulse width varies from a fraction of a micro second to
about 25 micro seconds. Usually a sufficient time elapses
before the next pulse appear.
The wave form of the output voltage at the secondary
terminal can be determine through the use of equivalent
circuit of the pulse transformer.
cont..

8. The transformer analysis is usually carried out by
dividing its solution in 3 parts:-
 Front edge of the pulse
 Response during the flat-top
 After the terminal of the pulse.
In order to keep the rise time within limits the leakage
inductance of the transformer be kept to a minimum.

9. 1.It separates high voltage power circuit from low voltage
control circuit.
2.These transformers are high frequency transformer thus
size reduces.
3.These transformer can have more than one secondary
side so we cant use more device at a time .
This is a high voltage transformer of
Pearson Electronics . It has voltage output
Of 100kV-500kV.This transformer is kept
in high voltage insulating oil

10. Pulse transformer-
Signal pulse transformers are used in digital
circuits, telecommunication etc.
Power pulse transformers are used to isolate
power circuit from control circuit.
High voltage pulse transformer-
These transformers are used in radar
application, for pulsed power application.

11. The pulse transformer are efficient in isolation and
protection of control circuit and widely used as it
takes small area due to small size. This prevents
wastage of space. One pulse transformer can have two
secondary sides this decreases the number of pulse
transformer and also decreases cost and complexity of
system.
