Abstract :
A 115 mm phi , 6 kV, 2500 A light-triggered thyristor has been developed for use in high-power converter applications such as static VAr compensators. The device has been implemented using ion implantation, large-diameter-element treatment, and cathode pattern design techniques. These techniques and the electrical characteristics of the thyristor are described. The device has on-state voltage of 3.0 V at 7800 A, minimum light-triggering power of 10 mW, dV/dt capability of more than 3000 V/ mu s, dI/dt capability of more than 300 A/ mu s, and turn-off time of less than 400 mu s.<>
