Thyristor devices for electric power systems
Thyristors of higher voltage and current ratings containing new gate and self-protective features are being developed at General Electric with EPRI (Electric Power Research Institute) support. Devices include light triggered thyristors (LTT's), now at the 5 and 6KV level, and asymmetric light triggered thyristors (ALTT's) with 50% higher surge capability and 50% faster turn-off times than a regular thyristor. New features include ''controlled turn-on'', which protects thyristors from destructive di/dt during turn-on, and ''voltage breakover'' (VBO) protection, which prevents destructive avalanche current turn-on. Brief descriptions of recent devices and status reports of various EPRI supported programs are given.
