Pulse Transformers

1. What are Pulse Transformers?

A pulse transformer is a type of reinforced transformer that generates high-speed, constant-amplitude electrical pulses. They are commonly used in digital information transmission and transistors (especially gate drive circuits).

 

2. How do Pulse Transformers Work?

A pulse transformer converts the voltage and current of an electrical pulse between two circuits while maintaining the electrical isolation barrier. This is achieved through two windings, one on the primary side and one on the secondary side, each with its own electrical characteristics. The primary winding receives the electrical pulse and induces a current in the secondary winding. This current is then converted to the desired voltage and current and transmitted to the secondary circuit.

 

3. What are the Advantages of Pulse Transformers?

Pulse transformers offer advantages such as compactness and good repeatability. Most applications require short rise times, wide pulse widths, and high energy conversion efficiency.

 

4. What are the Types of Pulse Transformers?

Flyback Transformer
