Thyristor, nke a makwaara dị ka Silicon Control Rectifier (SCR), bụ ngwaọrụ semiconductor nwere ike dị elu nke nwere usoro PN atọ.N'ihe banyere arụmọrụ, thyristor ọ bụghị nanị na ọ nwere unidirectional conductivity, kamakwa ọ nwere njikwa bara uru karịa ihe nrụpụta silicon rectifier, nke naanị steeti abụọ nke omume na mpụga steeti, iji chịkwaa nnukwu ike na obere ike, mmụba ike ruo narị otu narị ma ọ bụ ọtụtụ puku ugboro.Mmeghachi omume na-adị ngwa ngwa, na-agbanye ma gbanyụọ na micro-sekọnd.Arụ ọrụ na-enweghị kọntaktị, enweghị ọkụ, ọ dịghị mkpọtụ, ebe arụmọrụ dị elu na ọnụ ala dị ala.Ya mere, karịsịa na nnukwu ike ọkọnọ usoro, thyristor e ọtụtụ-eji na rectifier circuit, static bypass mgba ọkụ, kọntaktị-free mmepụta mgbanwe na ndị ọzọ sekit.

The thyristor n'ichepụta ọkọlọtọ na nhazi technology nke RUNAU Electronics e ẹkenam si USA ebe 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.On 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 ngwa nke ike electronics. ubi, na uru ka e kere maka mmekọ.
