Working principle

When this module is working, the integrated gate reversing thyristor plays a crucial role. After receiving the control signal, the gate precisely controls the conduction and turn off of the thyristor. When conduction is required, a suitable signal is applied to the gate to quickly conduct the thyristor, allowing large currents to pass through; When it is necessary to turn off, the gate quickly extracts carriers from the thyristor through a special commutation circuit, achieving fast turn off. Through this precise on/off control, precise regulation of current and voltage in the power system is achieved, thereby achieving precise control of connected devices.
