Thyristors, also known as silicon-controlled rectifiers, are devices that act as switching devices due to their unique characteristics. The MCR72-8G is a three-phase full-controlled thyristor module. It is especially suitable for applications such as frequency converters, UPS systems, soft starters, and welding machines. Its advantages include high surge current, high interference resistance and low electromagnetic interference (EMI).

The MCR72-8G is constructed with a direct-current link, a reverse-conduction device, and a trigger control part. When the latter is excited, the MCR72-8G becomes an open-circuit, allowing current to flow in one direction. It is then reclosed by the control part when the current has reached its desired level.

The working principle of the MCR72-8G is relatively simple. When a triggering current is applied, the MCR72-8G turns on and conducts current. As the current is passed through the device, it will enter the hold phase, meaning it will remain on unless the current is turned off.

The main application fields of the MCR72-8G are as a switching device for motors, pumps, heating units, castings, and fans. It is a powerful module for ensuring stable output in power supplies that require high reliability and accurate control of the current. It is also used in welding applications where high current and continual current are desired. In addition, it is used in medium-voltage applications, such as high-voltage AC grids, enabling the safe and efficient distribution of power.

In conclusion, the MCR72-8G is a reliable and highly efficient thyristor module which is suited for a variety of applications, such as power supplies, welding machines, and AC grids. Its working principle is relatively simple, resulting in a consistent, steady output when applied. It is versatile enough to be used for medium-voltage applications, as well as for small-scale systems, and its high surge current, interference resistance, and EMI capabilities make it a great choice for many applications.
