Specialized Pulse Transformer Circuit for High Load Applications

High Voltage Transformer
Industries such as power distribution, digital and telecommunications require fast and powerful electrical pulses for their load circuits. This kind of requirement cannot be fulfilled by step up or step down transformers. You need a specialized transformer to provide the required power. For such applications, Custom Coils provides the inimitable pulse transformer circuit.


Pulse Transformer Circuit Design and Operation

These transformers are designed to provide dielectric isolation between drive controller and power output circuits. The pulse transformer design offers galvanic isolation for gate drives of transformers. The assembly of the transformer can include PCB through hole mounting. Through hole mounting provides benefits of stronger electrical connections for the pulse transformer circuit. It also provides resistance to environmental stress.

We provide our pulse transformers in the following sizes:
  • Small (signal types)
  • Medium
  • Large

They provide negligible delay and room for voltage scaling. For multiple gate drives, the transformer can be designed single or double secondary windings.

Customized Offerings

We can provide custom designed products with basic, functional, and reinforced insulation. Solid insulation ensures that the transformer will not suffer from damages as a result of over voltage or accidental flashovers. Our custom designs can respond to external sensing circuits to prevent incidents of over voltage. We provide our transformers in various winding ratios and multiple package sizes.

Pulse Transformer Circuit Construction and Design/ Design Elements

Pulse transformer designs usually use low loss ferrite cores and operate at higher switching frequencies. The designs are centered on minimizing pulse distortion that includes issues like longer than normal rise times and voltage droop. These problems are often caused by unexpected increase in magnetizing current during the pulse. Other factors that influence these pulse distortions are leakage inductance and winding capacitance. The design also needs to consider the unipolar flux mode so that core saturation can be avoided.
