What is a pulse transformer?
A pulse transformer is an enhanced transformer that produces electrical pulses of great velocity and constant amplitude. They are often used in the transmitting of digital information and in transistors (particularly with gate drive circuits).
What is pulse transformer application?
Pulse transformers are used for the digitization of computers, measuring devices and pulse communication. Large versions of pulse transformers are used in the electrical power distribution industry in order to create a common boundary between low-voltage control circuitry and high-voltage gates of power semiconductors.
What is an Auto transformer How does it differ from a conventional two winding transformer also write its uses?
In two winding transformer, whole power is transferred from primary to secondary side by means of induction ONLY While, in the case of Auto transformer, part of the whole power is transferred by induction and rest of the power is transferred through conduction.
How does a pulse transformer work?
These types of transformers include insulation with high voltage in between two windings & toward the ground. Usually, these transformers handle the pulse signal otherwise train the pulse. The impulse transformers’ performance is mainly specified through its effect on the outline of the pulse input voltage or current.
What is the disadvantage of auto transformer?
The main disadvantage of an autotransformer is that it does not have the primary to secondary winding isolation of a conventional double wound transformer. Then an autotransformer can not safely be used for stepping down higher voltages to much lower voltages suitable for smaller loads.
Which core is used in pulse transformer?
1mil or 2mil silicon steel cores are used for these applications. Silicon core have advantage of high Bs (1.5T) compared to ferrite cores. Ferrite cores have low core losses but having disadvantage of low Bs (0.4T) which lead to larger core volume of the pulse transformer.
Why are pulse transformers used in thyristor circuits?
Pulse transformers are often used to couple a trigger pulse generator to a thyristor in order to obtain electrical isolation between the two circuits. … In some cases where high noise levels are present it may be necessary to load the secondary of the transformer with a resistor to prevent false triggering.
