A more efficient transformer can pay for itself many times over during its 25-year lifespan The transformer plays a key role in an electrical system’s efficiency and power quality, yet 95% of buying ...

Note: This article is based on the 2020 NEC. A transformer transfers electrical energy (power) from one system to another by induction, with no physical connection between the two systems (other than ...

Renewables are the preferred energies to fit the demand in the liberalized generation market in Spain. In particular, wind, solar and hydro benefit from government-sponsored tariffs, because they do ...

For the PDF version of this article, click here. The size, performance and cost of a power electronic system are closely linked to the like parameters of the magnetic components. Since custom power ...

Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...

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 ...

Power supply designers can increase efficiency while moving to a higher switching frequency. To prove this, engineers at Power Integrations tested comparable flyback designs running at 66 and 132 kHz.

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 ...
