Pulse Transformer

Pulse Transformer

Sometimes fast and powerful electrical pulses for load circuits are needed but cannot be achieved by step up/step down transformers. That’s how a pulse transformer comes into play to supply the required power.

Pulse transformers are engineered to provide dielectric isolation between drive controller and power output circuit. The assembly of pulse transformers includes PCB by hole mounting.


Features of Pulse Transformers

Pulse transformers focuses on minimizing pulse distortion caused by unexpected increase in magnetizing current during the pulse as well as leakage inductance and winding capacitance.

There are two main kinds of pulse transformers: power and signal. Power pulse transformers are turned on and off using a switching device at an operational frequency and pulse duration that ensures the pulse transformer receives the required amount of power. As a result of controlling the power, the temperature of the pulse transformer is also controlled. Additionally, the pulse transformer provides electrical insulation between the input winding and the output winding.

Signal pulse transformers handle relatively low amounts of power and deliver a series of pulses, or signals. This type of pulse transformer mainly focuses on the delivery of a signal at the output winding. Also, a signal pulse transformer can use its turns ratio to adjust signal amplitude and provide electrical resistance between the source and the load.

Applications of Pulse Transformer

Small versions of pulse transformers create the electrical surges that can be found in telecommunication and other applications such as camera flashes, radar equipment and particle acceleration. Medium versions of pulse transformers are used in electronic circuits.

Large versions of pulse transformers are used in the electrical power distribution industry in order to create a common boundary between low-voltage control circuitry and high-voltage gates of power semiconductors.
