Reviews
Thyristor (thyristor) module and rectifier diode module originated in the early 1970s, originally small and medium power thyristor module (working voltage ≤ 1000V, current ≤ 100a). After that, with the improvement of module production technology and the successful development of corresponding auxiliary materials, the volume and types of thyristor modules gradually increased. The technology of this series of product modules is now very perfect, the finished product rate is also very high, the use is also accompanied by universal and perfect, has become a key component of power control. At present, the thyristor module has already reached 2000a / 2500V.

Details
Thyristor and rectifier diode modules usually refer to all kinds of electrically connected bridge arm modules, single-phase rectifier bridge modules and thyristor modules.
There are usually two types of modules, i.e. insulated and non insulated. The insulation voltage between the front insulated chip and the chassis is above 2500V RMS, which is very convenient to use. One or more bridge arm modules can be installed on the same grounded radiator, and connected into various specifications of single-phase or three-phase full control, semi control rectification and other formats of lines, AC switches or other kinds of practical lines, thus greatly simplifying the line structure and reducing the size of the equipment. The latter type needs common anode and cathode to use, so it has great limitations in use, and the development trend is relatively slow.
According to the core installation technology and fixing method, the module structure can be divided into three types: common welding structure, crimping structure and DCB bonding structure, each of which has its own advantages and disadvantages. The common welding structure technology is simple, and there are few spare parts, so the cost is low. However, due to the thermal fatigue of solder and repeated power cycle, the module is easy to lead to field failure. Although the crimping structure solves the problem of thermal fatigue, the cost is high because of its complicated structure and many spare parts.The DCB bonding structure, which combines the advantages of the above two, overcomes their disadvantages, makes it have good thermal fatigue stability, and can be made into power modules with large electric flow and high integration.
