What is Pulse Transformer

What Is Pulse Transformer?

The transformers are used for various purposes in the sector of electricity. From the first invention in 1831 to the many present numbers of the transformer are designed. Some look oversized and heavyweight whole, and some look small and less weight. For many of them, the pulse transformer is one.

Definition of Pulse Transformer

The transformer steps up or down the voltage from one terminal to another terminal. It is also used for measuring the high voltage and current to the secondary terminal. The pulse transformer is an electric device that transmits the voltage by the package of a pulse.

It means voltage pulse transmission between the two windings of the transformer. The transformer can handle and isolate the currents and the voltage in the pulse so mostly within power electronic circuits and the loads.

Types of Pulse Transformer

A pulse transformer is also called a trigger transformer. It transmits voltage pulses between windings and the load..k Based on the pulses, these transformers are classified into two types:

  • Power pulse transformer
  • Signal pulse transformer

How Does a Pulse Transformer Work?

Pulse transformers are also called “pulse converters.” They convert electric power from AC to DC and vice versa. Pulse transformers are extensively used in the industry for converting AC power to DC power and vice versa.

Pulse transformers work on the principle of electromagnetic induction. When a current is passed through a coil of wire, it creates an electromagnetic field around it. This field induces a voltage in another coil of wire located close to the first coil.

Some of the main functions of pulse transformer are:

  • Voltage pulse amplitude can be changed
  • The pulse polarity can be changed
  • Pulse amplifier’s different stages can be coupled
  • Used like an Isolation Transformer

Pulse Transformer Voltage

As a pulse transformer, handle supply and current to make the electronic and electrical equipment source & load properly. Pulse transformers are used in radar, TV, digital computers, and many more. A standard pulse transformer output voltages range is from 100kV to 500kV.

Pulse Transformer Equation

Pulse transformer formula P1= 4*Kf*Klc*Koh*n0*Sc*Sok*J*B*F

Where:

  • Kf is the form of voltage or current: for breast = 1,11 for the rectangle = 1.
  • Klc – Factor of the geometric cross-section of the magnetic filler material ferromagnetic GLC = 0.6 – 0,95, and it is available in reference books on the magnetic elements.
    why – filling coefficient of the magnetic conductor window with the conductor sections
  • Koh = 0,35.
  • n0 – Coefficient showing which of the coil’s primary winding needed to n0 = 0,5 in transformers.
  • Sc – Section of the magnetic circuit.
  • Sok- The cross-section of the window
  • J – current density, with natural cooling 3500000 A / m2, forcing you can get to 6000000 A / m2
  • B – Induction of the operation of the magnetic circuit.
  • F- It is the frequency of the voltage or current Hz.

Pulse Transformer Equation

We will get the result if we give an example and use this formula. Here is an example.

Pulse Transformer at a Glance

A switching device controls the power transformer to turn it on or off. This switching device has an operating frequency and a pulse duration with the required power to control the temperature. A power transformer mainly provides electrical isolation between the input and output.

For the Pulse Transformer to work correctly, it needs water and electricity. The water will create a conductive surface which will allow the electric pulse to travel through it and into other objects or surfaces making contact with it.
