(PhysOrg.com) -- Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires ...

One of the most productive new approaches to power quality is immunity testing — making sure that loads can tolerate common disturbances without additional filtering or support. This kind of testing ...

CT20307 is an accurate reference voltage generator. In order to achieve a total error <2%, the amplifier in the bandgap core block implements an of ...

The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. June 25, 2013 2 min ...

Noise generators are very useful devices. They are used in test equipment, random number generators, etc. Usually, designers use special Zener noise diodes (at very low current) and transistors (with ...

The ISL24853A is a 15-channel I2C programmable reference voltage generator for TFT-LCDs featuring ultra-low power operation. It features 14 general purpose 10-bit DACs with buffered dual bank outputs, ...

Littelfuse has introduced an optically isolated photovoltaic gate driver for mosfets and IGBTs. Essentially, photovoltaic gate drivers are opto-isolated relays without the internal output mosfets, ...

A young researcher has put forward two protection techniques so that wind generators continue to be operative despite breaks in electricity supply. In his PhD, Jesús López Taberna put forward two ...

An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are used in the generation of electricity and in their simplest form consist of a coil ...
