dv kev / ua dt yog tus nqi them ntawm qhov hluav taws xob hauv SCR. Lawv txuas nrog hla lub thyristor kom tiv thaiv. Thecapacitor 'C' yog siv los txwv cov dv kev / ua dt ntawm SCR. Lub resistor 'R' yog siv los txwv kev tso tawm siab dhau los ntawm SCR. Thaum hloov S raug kaw, lub capacitor 'C' behavesas luv-circuit.

Raws li, lub hom phiaj ntawm Di DT tiv thaiv yog dab tsi?

di / dt kev tiv thaiv yog yuav tsum tau tiv thaiv thyristor los yog SCR los ntawm kev tsim ntawm lub zos hotspot vim tus nqi siab ntawm tus nqi ntawm kev hloov ntawm anode tam sim no i.e. di / ua dt nyob ze ntawm lub rooj vag mus rau cathode hlws ris thaum nws tig rau txheej txheem.

Ib yam li ntawd, kev tiv thaiv thyristor yog dab tsi? A thyristor yog ib qho khoom siv hauv lub xeev siv los hloov thiab tswj cov hluav taws xob tam sim no. Vim tus yam ntxwv no thiab dav kev tiv thaiv rating ntau, thyristors yog siv raws li cov tswj tam sim no. Tiv thaivthyristors yog siv rau overvoltage kev tiv thaiv.

Piv txwv li, DV dt thiab di DT yog dab tsi?

di / ua dt yog tus nqi hloov ntawm tam sim no thiab dv kev / ua dt yog tus nqi hloov ntawm voltage.

Dab tsi yog qhov kev ntsuas ntawm SCR?

Qhov siab tshaj tus nqi ntawm anode tam sim no, uas ib SCR tuaj yeem ua tau zoo (tsis muaj kev puas tsuaj), yog hu ua forwardcurrent kev ntaus nqi . Tam sim no ib txwm kev ntsuam xyuas ntawm SCRs yog los ntawm 30 A mus rau 100 A. Yog hais tias qhov tam sim no tshaj lub forwardcurrent kev ntaus nqi , cov SCR tuaj yeem raug puas vim yog cua sov ntawm cov junctions.
