  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).

Another application is in the aerospace and airline industries. Often airplanes use 400 Hz power so ...

  4. 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.
