Fast mgba ọkụ thyristor, na otu Ọdịdị na akara nke na-adọ akara thyristor, mgbe mma static e ji mara, karịsịa ike ike na-achọrọ site na elu ugboro ngwa nke rectification, chopping, inverter na ugboro ntụgharị circuit.Akụkụ dị ike nke thyristor ngwa ngwa bụ ntụgharị ọsọ ọsọ yana ịgbanwuo ọsọ mgbasawanye, ụgwọ mgbake na-adịchaghị ala, yana obere oge mgbanyụ, ọnụ ọgụgụ dị oke egwu ịrị elu nke ọnọdụ ugbu a (di/dt) na ọnụego dị oke egwu nke ịrị elu voltaji na-apụ apụ (dv/dt).Ogo nke thyristor ngwa ngwa n'ime oge a na-egosi anaghị ebelata ma ọ bụ na-ebelata ntakịrị mgbe ugboro na-abawanye.

The ngwa ngwa mgba ọkụ thyristor n'ichepụta ọkọlọtọ na nhazi technology nke RUNAU Electronics e ẹkenam si USA kemgbe 1980s, dị ka a ọsụ ụzọ nke n'ichepụta thyristor na China, teknuzu otu nke RUNAU enwetara ọnwụ-ọnụ ihe ọmụma na zuru n'ichepụta ahụmahụ ihe karịrị 30 afọ.Na isi nke omenala n'ichepụta usoro, talent technicians nke RUNAU Electronics emewo nkà-nke steeti technology n'ichepụta thyristor na uru atụmatụ nke European ngwaahịa, àgwà na arụmọrụ na-mma nke ukwuu, ọzọ nnukwu mmeri enweta na ike ngwá electronic ngwa, na uru ka e kere maka mmekọ.
