What are the differences between crimped and welded thyristor modules?

The thyristor module is a high-power semiconductor device that uses a module packaging form and has a four layer structure with three PN junctions. This type of thyristor module has a very small volume and compact structure, which plays a significant role in maintenance and installation. There are many types of thyristor modules, such as crimped thyristor modules, soldered thyristor modules, etc. Many people are not very clear about the differences between the two. Below, we will distinguish them in detail.


① In terms of current, welded modules can achieve a current of 160A, while crimped modules can reach a current of 1200A. This means that modules with a current lower than 160A are not only welded, but also crimped.


② In terms of appearance, welded modules are far from as good as crimped modules. crimped modules are integrally formed and have very standardized technology. Welded modules may have welding marks in some areas, but they have no impact during use.


③ As is well known, the market share of crimped thyristor modules is very large, and many companies use crimped thyristor modules. The reason for this may be due to their beautiful appearance. In addition, in terms of price, the cost of welded thyristor modules is much lower than that of crimped thyristor modules.
