A flyback transformer is a magnetic component used in switching power supplies to store energy during one part of a switching cycle and transfer that energy to the output during another. Unlike a conventional transformer, it does not transfer energy continuously from the primary to the secondary. Instead, energy is first stored in the magnetic…
A custom step up transformer is designed to increase voltage according to the specific electrical and mechanical requirements of an application. While standard transformers are available for common voltage and power requirements, some applications require non-standard voltage ratios, current ratings, insulation, dimensions, mounting arrangements, or winding configurations. Custom Coils designs and manufactures step up transformers…
A step down transformer is simply a device, which steps down or lowers the input voltage so that the secondary voltage is lower than the primary voltage. Why is this required? Voltage from a power plant often needs to be distributed to stations in nearby areas. Further more, this power must be stepped down from…
A step down transformer reduces a higher AC voltage to a lower voltage for distribution, equipment, and end-use applications. Utilities transmit power at high voltage to reduce resistive losses over long distances, then lower the voltage in stages at substations and distribution points until it matches what buildings and equipment are designed to accept. This…
Selecting a high voltage trigger transformer isn’t just about matching an output voltage. The part must deliver the right pulse amplitude, rise time, and repetition rate, withstand high voltage between windings, and fit the available space. Get any of these wrong and the result is unreliable ionization, laser misfires, or insulation failure. This guide covers…
What Are Custom Hydrogen Coils? Hydrogen coils are precision-wound magnetic components used in hydrogen generation equipment where consistent electrical performance and reliable construction are essential. Because every application carries its own electrical and dimensional requirements, these components are typically manufactured to customer specifications rather than pulled from a standard catalog. At Custom Coils, we build…
For OEM manufacturers and industrial equipment builders, sourcing a custom step down transformer built to documented specifications rather than adapting a catalog part helps improve system performance, integration, and production consistency. As a USA-based, ISO 9001:2015 certified step down transformer manufacturer, Custom Coils designs and manufactures low voltage transformers and custom transformer solutions engineered to…
Specifying a hydrogen coil correctly is only half the job. The other half is finding a hydrogen coil manufacturer who can actually build it consistently, to tolerance, across every order. For OEM buyers, that second half is where projects succeed or fail. Custom Coils has manufactured custom hydrogen coils, transformers, and inductors for OEM customers since 1967. This…
Every reliable power system depends on components that are built for the job not borrowed from a catalog and forced to fit. For power conversion applications with demanding performance, isolation, or environmental requirements, getting the design right from the start is not optional. It is the difference between a product that ships and one that…
A spark igniter is a compact, yet critical device used to initiate combustion in gas-based systems. In industrial settings, the 12V spark igniter is widely preferred because it balances safety, control, and ignition reliability. From HVAC burners to furnaces and process heating equipment, spark ignition remains a trusted method. This post explains how a spark…
