A transformer is used to make the voltage or current value increase or decrease from one terminal to another. It can work in high frequency. Pulse transformers are used for various types of work purposes. Its main function is to create a signal for a semiconductor device and provide electrical isolation. This blog will give a clear idea about the pulse transformer working principle.
Working Principle of Pulse Transformer
Consider a toroidal-shaped pulse transformer. The pulse transformer can work with high efficiency. The higher the inductance of the primary winding in a pulse transformer, the lower the magnetic current. The AC supplied to the initial winding of the transformer may reduce the saturation of the core.
Insulation between the two windings of the transformer can be secured to prevent any accidents, including short circuits. Since the winding of each winding is equal, either can be used as the primary or secondary winding.

Silicon-controlled transformers are called 1: 1 ratio transformers. The three-winding transformer SCR can provide a continuous signal. The ratio of transformers is 1:1:1.
The windings are kept separate in the middle of the transformer windings for additional protection through insulation. The output and input signals are the same for high signal frequencies. The frequency of the output and input signals is always proportional.
