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 ...

Single-phase toroidal variable transformer according to DIN VDE 0552, designed as autotransformer (autoconnected winding), with rotary switch and scale. Voltage adjustable between zero and max. value.

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 ...

HF radios often use toroidal transformers and winding them is a rite of passage for many RF hackers. [David Casler, KE0OG] received a question about how they work and answered it in a recent video ...

Given that the EU and FDA definitions of what constitutes a medical device encompass a large majority of medical products other than drugs, it is small wonder that the collective term ‘medical ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

A Shelton-based manufacturer of magnetic components and transformer products has been sold to an individual buyer.
