AC to AC conversion – a cycloconverter and cycloinverter converting an AC voltage to another AC voltage

A cycloconverter (CCV) or a cycloinverter converts a constant voltage, constant frequency AC waveform to another AC waveform of a lower frequencyby synthesizing the output waveform from segments of the AC supply without an intermediate DC link.There are two main types of CCVs, circulating current type or blocking mode type, most commercial high power products being of the blocking mode type.
