  2. Cycloconverter - Wikipedia

    en.wikipedia.org/wiki/Cycloconverter

    A cycloconverter (CCV) or a cycloinverter converts a constant amplitude, constant frequency AC waveform to another AC waveform of a lower frequency by synthesizing the output waveform from segments of the AC supply without an intermediate DC link (Dorf 1993, pp. 2241–2243 and Lander 1993, p. 181). There are two main types of CCVs, circulating ...

  3. AC-to-AC converter - Wikipedia

    en.wikipedia.org/wiki/AC-to-AC_converter

    A cycloconverter constructs an output, variable-frequency, approximately sinusoid waveform by switching segments of the input waveform to the output; there is no intermediate DC link. With switching elements such as SCRs , the output frequency must be lower than the input.

  4. Brainwave entrainment - Wikipedia

    en.wikipedia.org/wiki/Brainwave_entrainment

    Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...

    frequency converter An AC converter for changing the frequency. [p] forced characteristic (of a line commutated converter) A characteristic obtained by additional means, e.g. stabilization, with specified variation limits of influence quantities. fully controllable connection A uniform connection with all principal arms controllable ...

  6. Frequency changer - Wikipedia

    en.wikipedia.org/wiki/Frequency_changer

    A cycloconverter is also a type of frequency changer. Unlike a VFD, which is an indirect frequency changer since it uses an AC-DC stage and then a DC-AC stage, a cycloconverter is a direct frequency changer because it uses no intermediate stages. Another application is in the aerospace and airline industries. Often airplanes use 400 Hz power so ...

  7. Psychoacoustics - Wikipedia

    en.wikipedia.org/wiki/Psychoacoustics

    Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.

  8. Electromagnetic theories of consciousness - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_theories...

    The starting point for McFadden and Pockett's theory is the fact that every time a neuron fires to generate an action potential, and a postsynaptic potential in the next neuron down the line, it also generates a disturbance in the surrounding electromagnetic field.

  9. Tap converter - Wikipedia

    en.wikipedia.org/wiki/Tap_converter

    The tap converter is a variation on the cycloconverter, invented in 1981 by New York City electrical engineer Melvin Sandler and significantly functionally enhanced in 1982 through 1984 by graduate students Mariusz Wrzesniewski, Bruce David Wilner, and Eddie Fung.
