Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at extremely low temperatures. Superconductors, materials that exhibit this ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...

Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

A 2-pin plastic base with top contact, S-shaped envelope. Donor’s card reads: “Half-wave, thermionic, mercury-vapor rectifier made by Western Electric Company. Oxide coated filament, 2.5 volts at 3 ...
