Umgaqo osebenzayo kunye nomsebenzi ophambili we-thyristor

1. Umgaqo wokusebenza we kumnya Ngu:

1. Ukwenza i-thyristor ivule, enye kukufaka umbane oya phambili phakathi kwe-anode A kunye ne-cathode K, kwaye enye kukufaka i-voltage efanelekileyo phakathi kwe-electrode G kunye ne-cathode K. Emva kokuba i-thyristor ivuliwe, ukhulule iswitshi seqhosha, susa umbane wokubangela, kwaye ugcine imeko ikwimeko.

2. Nangona kunjalo, ukuba ubuyisele umva umbane kwi-anode okanye i-electrode yolawulo, i-thyristor ayinakuvulwa. Umsebenzi wepali yolawulo kukuvula i-thyristor ngokusebenzisa ukubetha okuhle, kodwa akunakucinywa. Ukucima ukuqhuba i-thyristor kunokucima umbane we-anode (tshintsha u-S kumzobo 3) okanye wenze i-anode yangoku ibe ngaphantsi kwexabiso elisezantsi lokugcina ukuqhuba (okubizwa ngokuba kukugcina okwangoku). Ukuba umbane we-AC okanye umbane we-DC oshukumisayo usetyenziswa phakathi kwe-anode kunye ne-cathode ye-thyristor, i-thyristor iya kucima ngokwayo xa i-voltage iwela i-zero.

Imisebenzi yale thyristor kwisekethe imi ngolu hlobo lulandelayo:

1. Isiguquli / isilungisi.

2. Lungisa uxinzelelo.

3. Ukuguqulwa rhoqo.

4. Tshintsha.

Omnye wemisebenzi ebaluleke kakhulu kwi-SCR kukuzinzisa okwangoku. I-Thyristors isetyenziswa ngokubanzi kulawulo oluzenzekelayo, iinkalo zombane zombane, izixhobo zombane kunye nezixhobo zekhaya. I-thyristor yinto esebenzayo yokutshintsha. Ihlala igcinwe kwimeko engadluliyo kude kube kuchukunyiswe ngumqondiso ongaphantsi kolawulo okanye “ukutshiswa” ukuyenza idlule. Nje ukuba icinywe, iya kuhlala ikwanjalo nokuba umqondiso we-trigger urhoxisiwe. Kwimeko yejelo, ukuyinqumla, amandla ombane anokuphinda afakwe phakathi kwe-anode kunye ne-cathode okanye ukuhamba ngoku okuhamba nge-diristor diode kungancitshiswa kungaphantsi kwexabiso elithile.
