Single Phase Cyclo Converter working Principle
Of Operation.
Cycloconverter converts power the AC Supply of one frequency into AC supply of different frequency.

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 forms of electrical energy commonly available are constant DC (Direct Current) and constant AC (Alternating Current). Often though, we need to swap between AC and DC, change the frequency, or swap from constant to variable power. For these conversion purposes, several converters like inverters, rectifiers, DC choppers and cycloconverters are employed.
The cycloconverters can in fact transfer AC power of a fixed frequency to the AC power of a different frequency.
The cycloconverter converts AC to AC whilst changing only the frequency. Hence it is also known as a frequency changer. Normally, the output frequency is less than the input frequency. There are no DC stages in between this conversion process. The implementation of the control circuit is complicated due to a large number of SCRs (Silicon Controlled Rectifiers). Microcontroller or DSP or microprocessor is used in control circuits.
