Thyristors - SCRs - Modules

IRKT57/06A is a kind of thyristor module, and it is usually used as a switch in some applications. IRKT57/06A thyristor module is Six-Pulse Thyristor Modules with symmetrical voltage / current, and it also has many features for such applications. Here in this article, we will discuss about the application fields and working principles of the IRKT57/06A thyristor module.

Application Field of the IRKT57/06A Thyristor Module

IRKT57/06A thyristor module is a kind of six-pulse thyristor module, which is suitable for use in switching applications in fields like power, electronics and controlling. Its rated voltage is higher than 2000 and it is suitable for use in both AC and DC main circuit. Its main application field includes controll of DC motors, starting or phase control of AC motors, and welding machine, etc. It can also be used as intelligent switch in domestic appliances.

Working Principle of the IRKT57/06A Thyristor Module

Generally, working principles for most thyristor modules are about the same. However, for the IRKT57/06A thyristor module, it is slightly different. The idea is that the six thyristors are connected in parrelled and trigered via the gate circuit in thge same phase. The thyristors in the circuit with their gates act as the switch. When the gate current reachs the opening level of the thyristor, the thyristor will turn on for a small period of time, and then it will turn off. The whole operation is just like the firing of six synchronous switchs. During the time of operation, the voltage and current of IRKT57/06A will be symmetrical and its switch time is in the range of millisecond.

Merits of the IRKT57/06A Thyristor Module

Comparing with other alternatives, the IRKT57/06A thyristor module has the following advantages:

• It has high-voltage, high-current and high-power capacity.
• It has low on-state voltage.
• It has quick response to switch signals.
• It is easy to control and fewer components are needed.

Conclusion

The IRKT57/06A thyristor module has wide application in power, controlling and electronics field, and the working principles and merits of it are all mentioned above. Anyhow, we can clearly see that the IRKT57/06A is a kind of high-efficient and reliable thyristor module.
