Isimiso sokusebenza nomsebenzi omkhulu we-thyristor

1. Isimiso esisebenzayo se ntombikayise Ngu:

1. Ukwenza i-thyristor ivuleke, enye ukusebenzisa i-voltage eya phambili phakathi kwe-anode A yayo ne-cathode K, kanti enye ukufaka i-voltage trigger phakathi kwe-electrode G yayo ne-cathode K. Ngemuva kokuthi i-thyristor ivuliwe, khipha inkinobho inkinobho, susa i-trigger voltage, futhi ugcine isimo sisesimweni.

2. Kodwa-ke, uma kusetshenziswa i-voltage eguquguqukayo ku-anode noma ku-electrode yokulawula, i-thyristor ayikwazi ukukhanyiswa. Umsebenzi wepali yokulawula ukuvula i-thyristor ngokusebenzisa i-positive pulse pulse, kepha ayikwazi ukucishwa. Ukucisha i-thyristor eqhuba kunganqamula ukunikezwa kwamandla kagesi (shintsha u-S kuMfanekiso 3) noma wenze i-anode ibe ngaphansi kwamanani aphansi kunenani eliphansi lokugcina ukuqhutshwa (okubizwa njengamanje okuqhubekayo). Uma i-voltage ye-AC noma i-DC evuthayo isetshenziswa phakathi kwe-anode ne-cathode ye-thyristor, i-thyristor izocima yodwa lapho i-voltage yeqa iqanda.

2. Imisebenzi yethristoror yakho kusekethe imi kanje:

1. Isiguquli / isilungisi.

2. Lungisa ingcindezi.

3. Ukuguqulwa kwemvamisa.

4. Shintsha.

Omunye wemisebenzi ebaluleke kakhulu ye-SCR ukuzinzisa okukhona manje. Ama-Thyristors asetshenziswa kakhulu ekuzilawuleni okuzenzakalelayo, izinkambu ze-electromechanical, izinto zikagesi zezimboni nezasendlini. I-thyristor iyinto esebenzayo yokushintsha. Imvamisa igcinwa isesimweni sokungadluli ize ibangelwe yisiginali yesilawuli esincane noma “ikhanyiselwe” ukuyenza idlule. Lapho nje isibaselwe, sizohlala noma ngabe i-trigger signal ihoxisiwe. Esimeni sesiteshi, ukusenza sinqunywe, amandla kagesi ahlehlayo angasetshenziswa phakathi kwe-anode ne-cathode noma okwamanje okugeleza nge-diristor diode kungancishiswa kube ngaphansi kwenani elithile.
