Working principle

Asymmetric integrated gate commutated thyristors combine the characteristics of thyristors and transistors. During the conduction stage, the gate receives a light trigger signal to quickly conduct the thyristor, allowing current to flow smoothly. When shutdown is required, integrated gate control technology is used to change the conduction state of internal electrons and achieve rapid shutdown. The patented free floating silicon technology optimizes the movement path of electrons inside the device, improving the efficiency of conduction and turn off; Low inductance packaging technology reduces energy loss and electromagnetic interference caused by inductance, ensuring stability during operation.

Precautions

Installation environment: It should be installed in a dry and well ventilated environment, avoiding damp, dusty, and strong electromagnetic interference places to prevent affecting the performance and service life of the device.

Electrical connection: When connecting circuits, it is important to ensure that the wiring is secure to avoid loose connections that may cause poor contact, heating, or even malfunctions. At the same time, it is necessary to strictly match electrical parameters according to product specifications to prevent overload operation.

Trigger signal: The transmission line of the light trigger signal should be kept intact, avoiding bending and damage, ensuring stable transmission of the trigger signal, and ensuring the normal operation of the thyristor.
