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

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 ...

The use of power electronics is increasing in the industry for both low-scale applications like chargers for batteries and LED drivers and high-scale applications like photovoltaic (PV) systems and ...

In this article, we discuss the basic operation and design of a Fly-Buck™ converter. This discussion also includes a detailed explanation about the control and regulation of this converter. The ...

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 ...

Cobham Technical Services claims that the development of new generations of transformers and line reactors is radically simplified and accelerated by a new automated software toolbox from its Vector ...

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 ...

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. The rapid buildout of fast-charging stations for electric vehicles is testing the limits of today’s ...

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 ...
