Nguwuphi umahluko ophambili phakathi kokusetyenziswa koonxantathu kunye nokungadibanisi thyristors?

I-SCRs zahlulwe zangacacanga kwaye zangqinelana ngamacala amabini, kwaye iisimboli zahlukile. Ii-SCR ezingadibaniyo zinendlela ezintathu ze-PN, kwaye ii-electrode ezimbini zitsalwe ngaphandle kwepali kunye nepali yeN, ebizwa ngokuba yi-anode kunye ne-cathode, ngokwahlukeneyo. Ipali yeP ikhokelela kwipali yokulawula.

Indlela-enye ye-SCR ineempawu zayo ezizodwa: xa i-anode iqhagamshelwe ukubuyisela umva umbane, okanye xa i-anode iqhagamshelwe kumbane wokuhambisa kodwa i-electrode yolawulo ayisetyenziswanga ombane, ayiqhubeki, kwaye xa i-anode kunye nolawulo lwe-electrode zixhunyiwe. Ukuhambisa umbane ngexesha elinye, Iya kuba yimeko yokuqhuba. Nje ukuba ivuliwe, umbane wolawulo ulahlekelwe sisiphumo solawulo. Nokuba kukho umbane wolawulo okanye ubungqongqo bevolthi yolawulo, iya kuhlala ikwisimo sokuqhuba. Ukuba ufuna ukucima, Kuphela ukunciphisa i-anode voltage kwixabiso elithile elibalulekileyo okanye ukubuyela umva.

Uninzi lwezikhonkwane ze-triac zilungiswe ukusuka ekhohlo ukuya ekunene ngokulandelelana kwe-T1, T2, kunye no-G (xa isikhonkwane se-elektrode siphantsi, sijonge kwicala ngabalinganiswa). Ubungakanani be-pulse pulse eyongezwe kulawulo lwe-electrode G okanye xa ixesha litshintsha, inokutshintsha ubungakanani bokuqhuba kwayo ngoku.

Umahluko kwi-thyristor engacacanga yeyokuba xa ubukhulu be-pulse ye-trigger kwi-bidirectional thyristor G itshintsha, indlela yayo yokuqhuba itshintsha notshintsho lwe-polarity, ukuze umthwalo we-AC ulawulwe. Emva kokuxhokonxwa, i-silicon inokuqhuba kuphela kwicala elinye ukusuka kwi-anode ukuya kwi-cathode, ke i-thyristor yakho ingangqinelani kwaye ibidirectional.

Ii-Thyristors zihlala zisetyenziswa kwimveliso ye-elektroniki, ezinje nge-MCR-100 yendlela enye kunye ne-TLC336 yeendlela ezimbini.
