thumb|Topology of blocking mode 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 ( and ). There are two main types of CCVs, circulating current type and blocking mode type, most commercial high power products being of the blocking mode type.
