Thyristors tsuas yog qhib tau siv lub rooj vag lead, tab sis tsis tuaj yeem muab tua siv lub rooj vag lead. … Yog li, lub thyristor coj zoo li ib txwm semiconductor diode tom qab nws tau qhib los yog "tawm". Lub GTO tuaj yeem qhib los ntawm lub rooj vag teeb liab, thiab tuaj yeem raug kaw los ntawm lub rooj vag teeb liab ntawm qhov tsis zoo polarity.
Peb puas tuaj yeem yuam thyristor kom tua?
Yog li, txhawm rau kaw qhov kev coj ua SCR kom raug, cov xwm txheej hauv qab no yuav tsum txaus siab: anode lossis xa mus rau tam sim no ntawm SCR yuav tsum raug txo kom xoom lossis qis dua qib tuavtam sim no thiab tom qab ntawd, Ib qho hluav taws xob rov qab txaus yuav tsum tau siv thoob plaws SCR kom rov ua tau nws txoj kev thaiv lub xeev tom ntej.
Kuv yuav ua li cas thiaj paub yog tias kuv lub thyristor phem?
Txuas negative lead ntawm koj ohmmeter rau lub anode ntawm SCR thiab cov hlau lead zoo rau cathode ntawm SCR. Nyeem cov nqi tiv thaiv uas tshwm sim ntawm ohmmeter. Nws yuav tsum nyeem tus nqi siab heev ntawm kev tiv thaiv. Yog tias nws nyeem tus nqi qis heev, ces SCR luv luv thiab yuav tsum tau hloov.
Kuv yuav ua li cas tig rau kuv lub thyristor?
Thyristor yog qhib los ntawm nce cov anode tam sim no ntws los ntawm nws. Qhov nce hauv anode tam sim no tuaj yeem ua tiav los ntawm ntau txoj hauv kev. Voltage Thyristor Triggering: - Ntawm no cov ntaub ntawv thov rau pem hauv ntej voltage yog maj mam nce ntau tshaj li pt.paub tias ua ntej tawg dhau voltage VBO thiab lub rooj vag qhib.
Vim li cas SCR tsis tuaj yeem muab tua?
Astwb tau hais nyob rau hauv tsab ntawv tshaj tawm yav dhau los, ib zaug SCR raug rho tawm haujlwm, nws tseem nyob txawm tias thaum ua rau lub plawv dhia tawm. Qhov peev xwm ntawm SCR nyob twj ywm txawm tias thaum lub rooj vag tam sim no raug tshem tawm raug hu ua latching. Yog li SCR tsis tuaj yeem muab tua by tsuas yog tshem lub rooj vag mem tes.
