Cycloconverter: Applications Types Electrical4U

2012-2-24  What is Cycloconverter A cycloconverter (also known as a cycloinverter or CCV) converts a constant voltage, constant frequency AC waveform to another AC waveform of a different frequency. A cycloconverter achieves this through synthesizing the output waveform from segments of the AC supply (without an intermediate DC link). The main

What Is a Cycloconverter? - Info Bloom

A cycloconverter is a device that converts alternating current, or AC, power at one frequency into AC power of an adjustable but lower frequency without any direct current, or DC, stage in between. It can also be considered as a static frequency changer and typically contains silicon-controlled rectifiers.
