PULSE TRANSFORMER

A transformer that is used to reproduce the pulse incident at primary side on the secondary with negligible phase displacement and amplitude is known as a pulse transformer.

 

A good transformer must have galvanic isolation and distributed capacitance. For circuit defence, capacitance with low coupling is also important to guard the circuit.

The major function of this transformer is to impart voltage pulses between windings and the load. 

 

These transformers are put into practice for galvanic isolation (signal transmission), low-power control circuits, and the main components required in high-power SMPS. By using this transformer, the amplitude in the voltage pulse can be changed; the polarity of the pulse can be inverted, coupling different stages in the pulse amplifier and isolation transformer. This transformer aims to impart a pulse for semiconductor devices as well as give electrical isolation.
