The application of electromagnetics has been in practice for more than a century: In 1831, English chemist and physicist Michael Faraday invented the transformer, although he called it an induction ...

An effective transformer design requires a determination of the peak values of the magnetic flux, the magnetic field strength, and the permeability of a core at low and high frequencies. These ...

Amorphous metal distribution transformers can minimize no-load losses in wind power applications. The offshore wind farm shown here is the Danish Horns Rev I. As part of its green transformer ...

While switch-mode power supplies operate at frequencies well above the range of human hearing, they can produce audible noise under certain load conditions. Potential sources of audible noise can vary ...
