➱GU-G04 GCU04AB-130 80173-111-01-2 COMMUTATED THYRISTOR BOARD

Having played a central role in the modernization of power electronics in the 1960s, large capacity thyristors are now handling higher voltages and currents. In the 1980s, it evolved from a reverse blocking thyristor without self-turn off function to a GTO (Gate Turn off) thyristor that switches from an ON to an OFF state by applying a negative gate signal even in a DC circuit. Furthermore, the GCT (Gate Commutated Turn off) thyristor was developed, inheriting the basic structure of the GTO thyristor but significantly reducing impedance of the gate to achieve high speed operation and high turn off performance.

The SGCT (Symmetrical Gate Commutated Turn-off) thyristor unit is a GCT thyristor with reverse voltage blocking capability and an optimally designed gate driver integrated into the unit, thus maximizing the performance of SGCT thyristors and reducing system design load.

High withstand voltage and reverse blocking types: Voltage rating: forward/6,500V, reverse/6,500V

Reduces power loss with low on-voltage, which is a characteristic of thyristors.

Optimal for high-voltage circuit breaker, current source inverter applications.
