Yuav ua li cas siv multimeter los txheeb xyuas peb tus ncej ntawm thyristor
Tus txheej txheem ntawm kev txheeb xyuas peb tus ncej ntawm SCR yog qhov yooj yim heev, raws li lub hauv paus ntsiab lus ntawm pN hlws ris, tsuav yog koj siv lub multimeter los ntsuas qhov ntsuas tus nqi ntawm peb tus ncej.
Kev tiv thaiv rau pem hauv ntej thiab thim rov qab ntawm lub anode thiab cathode yog ntau tshaj li ob peb puas kilo-ohms, thiab rau pem hauv ntej thiab thim rov qab ntawm lub anode thiab tus ncej tswj yog ntau tshaj li ob peb puas kilo-ohms (muaj ob peb pN junctions ntawm lawv, thiab cov kev taw qhia. yog qhov sib txawv, yog li cov anode thiab cov ncej tswj tsis tuaj yeem nkag mus rau ob qho tib si zoo thiab tsis zoo).
Nruab nrab ntawm tus ncej tswj thiab lub cathode yog pN hlws ris, yog li nws cov kev tiv thaiv pem hauv ntej yog nyob rau hauv thaj tsam ntawm ob peb ohms mus rau ob peb puas ohms, thiab qhov rov qab tsis kam yog ntau dua qhov kev tiv thaiv pem hauv ntej. Txawm li cas los xij, cov yam ntxwv ntawm tus ncej diode yog qhov tsawg dua qhov zoo tshaj plaws, qhov rov qab tsis tuaj yeem thaiv lub xeev tag nrho, tuaj yeem muaj qhov tam sim no loj heev los ntawm, yog li ntawd, qee zaum ntsuas tus ncej thim rov qab kuj me me, tsis txhais tau hais tias tus ncej tswj tus yam ntxwv yog. tsis zoo. Tsis tas li ntawd, thaum ntsuas tus tswj ncej rau pem hauv ntej thiab thim rov qab, lub multimeter yuav tsum tau muab tso rau hauv R * 10 lossis R * 1 thaiv, txhawm rau tiv thaiv kev tiv thaiv hluav taws xob siab rov qab tawg.
Yog hais tias qhov ntsuas tivthaiv cathode thiab anode zoo thiab tsis zoo tau raug luv luv, lossis anode thiab tswj ncej luv-circuit, lossis tswj ncej thiab cathode thim rov qab luv luv-circuit, lossis tswj ncej thiab cathode tawg, qhia tias cov khoom puas lawm.
Thyristor yog cov ntawv luv ntawm silicon tswj rectifier, yog lub zog hluav taws xob semiconductor nrog peb pN hlws ris ntawm plaub txheej txheej. Qhov tseeb, kev ua haujlwm ntawm SCR tsis yog tsuas yog kev kho kom zoo xwb, nws tseem tuaj yeem siv los ua kev hloov pauv sai sai rau lossis tawm hauv Circuit Court, qhov kev paub ntawm cov tam sim no ncaj qha mus rau hauv alternating tam sim no inverter, zaus ntawm alternating tam sim no mus rau lwm zaus ntawm alternating. tam sim no, thiab lwm yam. Thyristor thiab lwm yam khoom siv semiconductor, nws muaj qhov me me, kev ua haujlwm siab, zoo stability, txhim khu kev qha thiab lwm yam zoo. Nws cov tsos, thiaj li hais tias cov tshuab semiconductor los ntawm lub teb ntawm cov hluav taws xob tsis muaj zog mus rau hauv lub tshav pob hluav taws xob muaj zog, ua kev lag luam, kev ua liaj ua teb, kev thauj mus los, kev tshawb fawb tub rog thiab txawm tias kev lag luam, cov khoom siv pej xeem thiab lwm yam kev sib tw rau kev siv cov khoom siv.
