Thyristors have been around for many decades and remain popular today due to their robust and reliable nature and their ability to be used in a wide range of applications. The SMP80MC-160 is a thyristor module that is used in a variety of applications and is particularly suitable for use as a medium power control switch. Here, we will discuss the application fields and working principle of the SMP80MC-160.

The SMP80MC-160 is a 3 phase controllable silicon controlled rectifier (SCR) module that is suitable for cyclic devices and medium power applications up to 1600A. This is a modular solution with built-in temperature compensation and built-in protection against overload and short circuit. It has a coefficient of transition of 0.50, allowing for smooth and efficient switching from one point to another. The module also has an insulation level of 3800V for safety.

The SMP80MC-160 is primarily used as a power switch for three-phase motors and induction heaters. It offers a choice of five different configurations, allowing for maximum flexibility in the application. These different configurations are: 1) Standard constant-current rectifiers, 2) Soft-start rectifiers, 3) Choke-start rectifiers, 4) Star-lambda rectifiers, and 5) Delta-delta rectifiers. By choosing the appropriate configuration, the user can tailor the SMP80MC-160 to meet a wide range of power control requirements.

From a working principle point of view, the SMP80MC-160 employs a triangular wave technology to control the switching of thyristors. This technology utilizes a reference voltage to create a saw-tooth wave on the gate of a thyristor which, in turn, causes the thyristor to switch "on" at each peak. This switching frequency of the SMP80MC-160 can be adjusted according to the desired application, allowing for maximum control over the application.

The SMP80MC-160 also has several built-in safety features. The most important of these are the overpressure and overload protection. These protect the thyristor from any excessive current that may be caused by a short circuit. This feature ensures a reliable and durable performance from the module. Additionally, the SMP80MC-160 has built-in thermal protection which helps protect against any potential overheating.

In conclusion, the SMP80MC-160 is a versatile thyristor module that is suitable for a wide variety of applications. The modular design and built-in safety features provide a reliable and robust solution for any power control application. The SMP80MC-160 is easy to install and offers maximum flexibility in terms of configuration options and adjustment of switching frequency. With these features, the SMP80MC-160 is an excellent choice for medium power controllable switching applications.
