Taw qhia rau thyristor

Silicon Controlled Rectifier (SCR), tseem hu ua thyristor, yog cov khoom siv hluav taws xob muaj zog. Nws muaj qhov zoo ntawm qhov me me, kev ua haujlwm siab, thiab lub neej ua haujlwm ntev. Hauv cov tshuab tswj tsis siv neeg, nws tuaj yeem siv los ua tus tsav tsheb muaj zog los tswj cov khoom siv hluav taws xob siab nrog cov tswj hluav taws xob tsawg. Nws tau dav siv nyob rau hauv AC thiab DC lub cev muaj zog tswj kev ceev, kev tswj fais fab, thiab servo systems.

Muaj ob hom thyristor: unidirectional thyristor thiab bidirectional thyristor. Bidirectional thyristor, tseem hu ua peb-terminal bidirectional thyristor, abbreviated li TRIAC. Bidirectional thyristor yog structurally sib npaug rau ob unidirectional thyristors txuas nyob rau hauv thim rov qab, thiab hom thyristor no muaj bidirectional conduction muaj nuj nqi. Nws lub xeev on/off yog txiav txim los ntawm tus tswj ncej G. Ntxiv ib tug zoo (los yog tsis zoo) mem tes rau tus tswj ncej G tuaj yeem ua rau nws coj mus rau pem hauv ntej (los yog thim rov qab). Qhov zoo ntawm cov cuab yeej no yog qhov kev tswj xyuas hluav taws xob yog qhov yooj yim thiab tsis muaj qhov rov qab hluav taws xob tiv thaiv teeb meem, yog li nws yog qhov tshwj xeeb tshaj yog siv los ua AC contactless hloov.
