80026-524-01-R Gate module commutator thyristor
The main differences between GTO thyristors and ordinary thyristors are as follows:
Design and process: the size of α2 is considered in the design of GTO thyristor, which makes the transistor V2 control sensitive and easy to GTO shut off. Ordinary thyristors do not have this design.
Conduction characteristics: the α1+α2 of GTO thyristor during conduction is closer to 1, the saturation degree is not deep, close to critical saturation, which provides favorable conditions for gate control shutdown. However, the α1+α2 of ordinary thyristors is usually greater than or equal to 1.15, and the saturation degree is deep during conduction.
Shut-off process: GTO thyristors have strong positive feedback during the shut-off process, making them exit saturation and shut off. Ordinary thyristors do not have this characteristic.
Structure and performance: GTO thyristor adopts multi-component integrated structure, which makes its base lateral resistance small and can draw large current from the gate. This makes the opening process of GTO thyristors faster than that of ordinary thyristors, and the ability to withstand di/dt is enhanced.
In summary, GTO thyristors and ordinary thyristors have significant differences in design and technology, conduction characteristics, turn-off process, structure and performance. These differences allow GTO thyristors to have higher efficiency and performance in some applications.
