In industrial applications two forms of electrical energy are used Direct current (DC) and AC (AC). Constant voltage and constant current AC are directly available. However, different shapes, different voltages and / or different currents are required for different applications. Converters are needed to achieve different shapes. These converters are classified as rectifiers, switches, inverters and cycloconverters.
A cycloconverter is a device that converts AC, power to an alternating current frequency of an adjustable frequency but smaller without direct current, or DC, between stages. It can also be recognized as a static recurrent charger and has rectifiers regulated by silicon. Cycle converters are used in very large variable frequency units with ratings from a few megawatts to many tens of megawatts.
The cycle-converter principle is described below using single-phase to single-phase cycle-converter.

The Cycloconverter has traditionally been used only in very high power units, usually above a megawatt, where no other type of unit can be used. Examples are cement tube mill drives above 5 MW, German-Dutch wind tunnel fan of 13 MW, reversible rolling mill drives and boat propulsion drives. The reasons for this are that the traditional cycloconverter requires a large number of thyristors, at least 36 and usually more for good motor performance, coupled with a very complex control circuit, and has some performance limitations, the worst of which is An output frequency limited to about one-third of the input frequency.
