    What are the applications of cycloconverters? - Quora

    Answer (1 of 2): A cycloconverter converts mains frequency (50 or 60Hz) into a low frequency output. This output frequency is an integral fraction of the input frequency: fout = (1/n) * fin where n = 1, 2, 3….. A common use for this is to run very large synchronous motors in
