When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

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 ...

The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

Magnetic components, particularly transformers operating at high frequencies and voltages, are intrinsically influenced by parasitic capacitance. This unintended capacitance between conductive ...

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...
