  2. Buck converter - Wikipedia

    en.wikipedia.org/wiki/Buck_converter

    The input is left side, the output with load is right side. The switch is typically a MOSFET, IGBT, or BJT transistor. A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input ( supply) to its output ( load ). It is a class of switched-mode power supply.

  3. Explosively pumped flux compression generator - Wikipedia

    en.wikipedia.org/wiki/Explosively_pumped_flux...

    An explosively pumped flux compression generator ( EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive . An EPFCG only ever generates a single pulse as the device is physically destroyed during operation. They require a starting current pulse to operate, usually supplied by ...

  4. Van de Graaff generator - Wikipedia

    en.wikipedia.org/wiki/Van_de_Graaff_generator

    Van de Graaff generator. A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels.

  5. Free-piston engine - Wikipedia

    en.wikipedia.org/wiki/Free-piston_engine

    Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).

  6. How To Report On Jail Deaths - The Huffington Post

    Contact the local sheriff and police departments to determine how many facilities hold new detainees, even if it's only for 24 to 72 hours. If a local jail doesn't send out press releases about deaths — many don't — file public records requests to obtain unreported deaths. 2. Initial reporting on new deaths. When reporting a new death, seek ...

  8. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    Homopolar generator. Faraday disk, the first homopolar generator. A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder ...

  9. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[ 1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...
