Menene babban bambanci tsakanin amfani da triacs da unidirectional thyristors?

An raba SCR zuwa unidirectional da bidirectional, kuma alamomin ma sun bambanta. Unidirectional SCRs suna da magudanar PN guda uku, kuma ana zana wayoyin lantarki guda biyu daga filayen P na waje da N, waɗanda ake kira anode da cathode, bi da bi. Pole P yana kaiwa zuwa sandar sarrafawa.

Hanya ɗaya SCR tana da halaye na musamman: lokacin da aka haɗa anode don juyawa ƙarfin lantarki, ko lokacin da aka haɗa anode zuwa ƙarfin lantarki na gaba amma ba a amfani da wutar lantarki ba, ba ta yin aiki, kuma lokacin da aka haɗa anode da electrode electrode. don tura ƙarfin lantarki a lokaci guda, Zai zama jihar gudanarwa. Da zarar an kunna, ƙarfin sarrafawa yana rasa tasirin sarrafawa. Ko da kuwa akwai ƙarfin sarrafawa ko kuma polarity na ƙarfin sarrafawa, koyaushe zai kasance cikin yanayin gudanarwa. Idan kuna son kashe, kawai don rage ƙarfin anode zuwa wani ƙima mai mahimmanci ko juyawa.

Yawancin fil ɗin triac ɗin an shirya su daga hagu zuwa dama a cikin tsari na T1, T2, da G (lokacin da pin electrode yake ƙasa, yana fuskantar gefe tare da haruffa). Girman bugun bugun bugun da aka kara zuwa electrode mai sarrafawa G ko Lokacin lokacin ya canza, zai iya canza girman yadda ake gudanar da shi.

Bambanci tare da unidirectional thyristor shine cewa lokacin da polarity na pulse pulse a kan bidirectional thyristor G ya canza, shugabancin jagorarsa yana canzawa tare da canjin polarity, don a iya sarrafa nauyin AC. Bayan an haifar da shi, silicon zai iya yin jagoranci a hanya ɗaya daga anode zuwa cathode, don haka thyristor na iya zama ba tare da umarni ba.

Ana amfani da Thyristors a cikin samar da lantarki, kamar MCR-100 don hanya ɗaya da TLC336 don hanya biyu.
