The O-Core toroidal power transformer cores enable the production of transformers that are 15% smaller in size and weight than traditional toroidal transformers. The cores use a silicon steel strip ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...

Wound-toroid inductors have been the mainstay for desktop core voltage regulators (V CORE) for years. Historically, the bulky size, sloppy tolerances and high power losses of these inductors were not ...

One of the best tools in the engineer’s lightning protection toolbox is a tried, true and frequently underutilized friend, the ferrite toroid. The principle is quite simple. If you have two (or more) ...

When you need a toroid the easiest source is often to wind it yourself. The problem being that placing a few hundred windings around a ferrite ring is a real drag, especially if you have to make ...
