Lub diode yog ib qho khoom siv semiconductor thiab yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws hauv cov khoom siv hluav taws xob. Nws muaj unidirectional conductive xwm, cia tam sim no ntws mus rau hauv ib qho kev taw qhia nkaus xwb. Cov cuab yeej no ua rau diodes dav siv hauv hluav taws xob circuits. Txawm li cas los xij, muaj ntau yam teeb meem uas tshwm sim thaum diodes siv nyob rau hauv parallel, thiab tsab xov xwm no yuav piav qhia txog cov teeb meem no thiab piav qhia vim li cas lawv yuav tsum tsis txhob siv nyob rau hauv parallel. Peb yuav piav txog peb yam tseem ceeb:
I. Kev tsim cov txheej txheem sib txawv thiab cov yam ntxwv voltammetric ntawm diodes
Parameter sib txawv ntawm diodes yog ib qho ntawm cov laj thawj vim li cas lawv tsis tuaj yeem siv ua ke. Txawm hais tias cov tuam ntxhab tuaj yeem ua lawv qhov zoo tshaj plaws los xyuas kom meej tias qhov tsis sib xws ntawm diodes, hauv kev xyaum cov kev ntsuas no tuaj yeem sib txawv. Piv txwv li, ntau qhov chaw tsim khoom, qhov kub thiab txias thiab lwm yam yuav ua rau muaj qhov sib txawv ntawm qhov tsis xws li tam sim no, saturation tam sim no thiab rov qab saturation tam sim no.
Cov yam ntxwv tam sim no-voltage ntawm ib lub diode yog non-linear, raws li qhia hauv qab no
Qhov sib txawv me me heev ua rau qhov sib txawv tam sim no loj heev.
Thaum ob lub diodes uas zoo tib yam voltammetric yam ntxwv siv nyob rau hauv parallel, lub tam sim no ntawm ob lub diodes yuav tsis muab faib raws li theoretical qhov tseem ceeb vim qhov txawv voltage tee tshwm sim los ntawm manufacturing txheej txheem deviations, uas nyob rau hauv lem ua rau ib tug unevenly faib tam sim no, thiab qee qhov diodes tuaj yeem tshaj lawv qhov kev tso cai txwv, uas tuaj yeem ua rau kev puas tsuaj rau diode.
Yog tias diodes nrog cov yam ntxwv sib txawv voltage-tam sim no txuas nrog rau qhov sib npaug, qhov no yuav ua rau ib qho ntawm cov diodes nqa feem ntau ntawm cov khoom thauj, thaum lwm cov diodes yuav luag tsis muaj tam sim no dhau los ntawm lawv, yog li tsis ua tiav qhov sib npaug tam sim no.
II. Cov yam ntxwv kub
Qhov cuam tshuam ntawm qhov kub ntawm diodes yog qhov tseem ceeb thiab tuaj yeem cuam tshuam rau lawv cov yam ntxwv tam sim no-voltage thiab lwm yam hluav taws xob tsis zoo. Thaum siv cov diodes nyob rau hauv parallel, qhov cuam tshuam ntawm qhov kub thiab txias tuaj yeem ua rau muaj qhov sib txawv loj hauv qhov tam sim no-voltage yam ntxwv ntawm ob lub diodes, uas ua rau lub diodes tsis tuaj yeem sib npaug tam sim no zoo.
Thaum qhov tsis txaus ntseeg tam sim no ua rau ib lub diode ua kom kub hnyav thiab ib lub diode tsis tuaj yeem ua kom sov, qhov no ua rau qhov tsis txaus ntseeg tam sim no thiab nws thiaj li ua rau muaj kev puas tsuaj rau ib qho ntawm cov diodes.
III. Cov dej ntws tam sim no
Thaum siv diodes nyob rau hauv parallel, to tam sim no kuj yog ib qho ntawm cov yam uas yuav ua rau cov tam sim no tsis sib npaug. Yog hais tias ob lub diodes nrog cov sib txawv to taub tam sim no txuas nrog rau qhov sib npaug, qhov xau tam sim no yuav ua rau qhov tam sim no tsis sib npaug zoo hauv qab kev tsis ncaj ncees. Lub diode nrog cov dej xau ntau dua yuav nqa tam sim no ntau dua, uas tuaj yeem ua rau ib qho diode raug overloaded thiab puas. Tsis tas li ntawd, raws li cov xau tam sim no yuav txawv ntawm diode mus rau diode, qhov no tuaj yeem ua rau qhov tsis sib xws ntawm qhov hluav taws xob ntawm tus kheej diodes, uas nyob rau hauv lem yuav ua rau tam sim no tsis sib npaug.
