| Abstract: | This paper detailedly analyzes the design principle of light triggered thyristor. By special gate structure and processes design, a light-triggering function, a break-over diode, a turn-on protection resistor, a forward recovery protection function as well as dv/dt protection function are all integrated in 5 inch single chip. The wafer＇s blocking voltage is more than 7600V and its current capacity is higher than 3125A. Tested data shows the technology parameters of the devices arriving to the equivalence level of the foreign congener product. The devices have been successfully used in ＂YUN-GUANG ＋-800KV/5000MW＂ UHVDC project in China. |
