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 ...

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 ...

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 ...
