Pulse transformers are widely used across a variety of industrial fields. They are designed to carry a high amount of loads and to distribute power. They are designed to transform more energy than regular transmitters of similar size. They can operate on high frequencies. They help to minimize voltage drop and rise time and also pulse distortion.

A pulse transformer is capable of operating at high frequencies. These transformers are commonly used for low power circuits, high power supplies. Pulse transformers are used for signal transmission. In this article, we will discuss the reasons why these are becoming popular.

They can transfer high energy

The sizes of pulse transformers are compact. They offer great repetitiveness. One of the primary advantages of custom pulse transformers is making the smaller components work more. It can transform high energy very aptly with a short rise time and wide pulse width.

Its ferrite core has high permeability. This further helps in reducing the leakage inductance. Pulse transformers have high voltage resistance, which makes them practical for large-scale operation.

Winding More

Most of the pulse transformers have more than two windings. Those windings are used to drive several transistors in a simultaneous order. Due to this advantage, any phase shifts and delays don't become a big issue, keeping it to a minimum. Hence with more than two wings, pulse transformers can utilize several transistors together. Less turns quotes to more power and less resistance.

Stray Current Preventing

Pulse transformers have galvanic isolation among their windings. It prevents the passing of stray currents and allows the primary driving circuit. It also lets the secondary-driven circuit use different potentials.

The isolation usually ranges between 4kV for small-sized electronic transformers. While the range is 200 kV for very high power applications. The galvanic isolation property fulfils the safety requirements. Thus it saves from potential damages if one part is not safe for touching because of the high voltage passes by,

Vacuum Potting

Pulse transformers are the ones that are encapsulated with abrasive resins. Abrasive resins help control all kinds of electric vibration and resistance within a transformer in a controlled atmosphere.

The name of this process is vacuum potting. Makers use silicone rubber gels and thermo-setting plastics for potting within the transformer. The potting compound acts as an insulator. This also helps to minimize the required space resulting in better insulation.

Some More to Know

Pulse transformers are used for signal transmission, low power control circuits, and as the main components in high voltage levels. Low power pulse transformers are used to control switching elements, while gate drive type is used.

The distinction is based on the actual purpose. Power transformers are used in transmission networks to step down the higher voltage to lower voltage. The transformer is used to drive a transistor gate. Distribution transformers further step it down to drive industrial and commercial loads.


Pulse transformers are custom transformers that allow greater energy efficiency for different industries. The utility & telecommunication industry is such one. Pulse transformers step up or down power to certain levels. Solid insulation is part of the custom design that protects the transformer from damage due to excessive voltage.

Here’s to the hoping that this blog helped answer the questions you had about pulse transformers and their growing uses.
