What is the cycloconverter?

Cycloconverter is a device that converts an alternating current or alternating current at a single frequency to alternating power adjustable but lower frequency without any direct current or DC, between them. It can also be considered a converter of static frequencies and usually contains rectifiers controlled by silicon. The device consists of a back-to-back field, parallel, connected switches that are used to produce the required AC current outputs. It is possible to control the frequency of these outputs of the AC current by opening and closing the switches controlled. Usually, the output frequency of the AC power is lower than the input frequency. Cycloconverter has the ability to work with many variable energy factors and also allows two -way energy flow. They can be widely classified into two types - PHAe -controlled cycloconverters and Cykloconverters. In the first case, the shooting angle check is performed using adjustable gate pulses whileIn the latter, the switches remain in the state of he and the behavior in consecutive half cycles.

They are mostly used to control disk speeds and to convert the input frequency performance into constant frequency output, for example in very high -performance applications, including synchronous motors and induction motors. The places where cycloconverters are used include discs of cement mills, mining windows and ground mills. They are also used in drives for boat drives, Scherbius discs and rolling discs.

offers many advantages, cycloconverter can be used in several low -speed applications and is also a compact system. His ability to directly influence the frequency transformation of energy without any huge advantage is the Ntermediata Stage including DC Power. If the Cykloconverter experiences commutation failure, the results are minimal such as blowing individual insurancek.

also has a regeneration capacity and covers the overall speed range. Another huge advantage of the cycloconverter is its ability to supply sinus course at a lower output frequency. This advantage comes from its ability to synthesize the output course using a large number of segments of the input course.

However, this technology has certain disadvantages. First, the frequency of output power is approximately the third or less input frequency. It is possible to improve the quality of the output course if a larger number of switching devices are used. The cycloconverter requires a relatively complex control mechanism and also uses a large number of thyristors. Its use is also limited by severe harmonious and frequency ranges with low power.
