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 ...

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 (auto-connected winding), with rotary switch and scale. Voltage adjustable between zero and max. value ...

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 ...

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 ...
