cycloconverter

[¦sī·klō·kən′vərd·ər]
(electricity)
A device that produces an alternating current of constant or precisely controllable frequency from a variable-frequency alternating-current input, with the output frequency usually one-third or less of the input frequency.

1) include: TK--a thyristor switch of a cycloconverter type with natural switching as which a direct thyristor frequency converter (DTFC) serves, G-asynchronized generator as which as a three-phase asynchronous machine with a phase rotor, the coils of which the rotor phases are connected in a star serves.
A matrix converter, also called a cycloconverter, transfers AC supply directly into an AC load of a different frequency.
In the direct power converter category, forced-commutated Matrix Converter (MC) stands alongwith the cycloconverter. The conventional matrix converter having three inputs and three outputs has attracted substantial research consideration over since its inception, with high prospects that it may be the eventual pure-silicon power conversion elucidation.
