Kev txwv tsis pub dhau los thiab kev tiv thaiv ntawm diodees hauv pob ntseg

1, cov ntsiab cai yooj yim thiab cov yam ntxwv ntawm dodes
Diode yog semiconductor ntaus ntawv nrog unidirectional conductivity, thiab nws cov tub ntxhais nyob hauv cov khoom tshwj xeeb ntawm PN hlws sib tshuam. Ib qho kev sib tshuam PN yog tsim los ntawm cov txheej txheem doping ntawm p- hom semiconductor thiab n - hom semiconductor. Thaum twg rau pem hauv ntej voltage yog thov mus rau lub pn kev sib tshuam, tus Diode ua, tso cai tam sim no kom dhau los ntawm; Thaum rov qab voltage yog thov rau lub pn kev sib tshuam, Diode txiav tawm, tiv thaiv kev hla dhau los ntawm kev hla dhau. Qhov kev coj ua tsis zoo no ua rau muaj kev ua haujlwm zoo
Hauv lub mloog pob ntseg, diodes yog tsuas yog siv rau kev txwv tsis pub dhau thiab kev tiv thaiv. Thaum lub mloog pob ntseg tau txuas nrog cov khoom siv suab, cov khoom tawm ntawm lub mloog suab tsis ruaj khov yuav tsis ruaj khov lossis siab dua, thiab siv hluav taws xob puas tsuaj rau hauv lub mloog pob ntseg sab hauv. Txij ntawm no, cov Diode ua raws li lub neej tam sim no, uas tuaj yeem txwv qhov kev hla ntawm lub pob ntseg no, yog li tiv thaiv lawv los ntawm kev puas tsuaj.
2, tam sim no muaj kev cuam tshuam tam sim no ntawm dodes hauv pob ntseg
Tam sim no limerving tiv thaiv
Cov haujlwm tseem ceeb ntawm diodees hauv pob ntseg hauv lub mloog pob ntseg yog txwv tsis pub tam sim no. Vim yog cov rhiab ntawm tus neeg hais lus thiab lwm lub pob ntseg hluav taws xob mus rau qhov ntau ntawm tam sim no, ntau tam sim no tuaj yeem ua rau tivtiv kev puas tsuaj lossis kev ua haujlwm tsis zoo. Los ntawm kev sib txuas nrog Diode hauv koob nyob hauv lub mloog pob ntseg Circuit Court, rau pem hauv ntej cov hluav taws xob poob cov yam ntxwv tuaj yeem siv los txwv qhov tam sim no. Thaum cov tam sim no dhau lawm, rau pem hauv ntej Voltage poob ntawm cov Diode nce, yog li txwv qhov ntau ntawm cov tam sim no thiab tiv thaiv cov hluav taws xob Cheebtsam sab hauv lub mloog pob ntseg.
Ruaj khov tam sim no
Ntxiv nrog rau kev txwv qhov loj tam sim no, diodes tseem tuaj yeem tswj qhov tam sim no rau qee yam. Vim tias qhov cuam tshuam tau zoo tshaj plaws rau pem hauv ntej Voltage poob ntawm ib qho nyob rau hauv ib qho kev tawm suab, yog qhov tsis txaus ntseeg ntawm lub ntsej muag tam sim no los ntawm lub mloog pob ntseg. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev ua kom muaj lub suab zoo thiab ua haujlwm ntawm lub mloog pob ntseg.
3, kev tiv thaiv cov nyhuv ntawm diodees hauv pob ntseg
Tiv Thaiv Kev Tshaj Tawm
Overload yog ib qho ntawm cov kev ua yuam kev hauv lub mloog pob ntseg. Thaum cov zis tam sim no cov twj tso suab siab dhau, tsis muaj kev tiv thaiv kev tiv thaiv tsim nyog, hluav taws xob hluav taws xob sab hauv lub pob ntseg yuav raug puas ntsoog. Raws li tam sim no limects, diodes tuaj yeem teb sai sai thiab txwv qhov tseem ceeb ntawm cov khoom siv hluav taws xob sab hauv lub mloog pob ntseg sab hauv lub mloog pob ntseg los ntawm kev puas tsuaj vim yog overheating.
Suppress Transient Voltage
Ntxiv rau kev tshaj tawm, kev hloov pauv khoom ntawm chaw nyob kuj tseem muaj kev hem thawj hauv lub mloog pob ntseg. Transient voltage tej zaum yuav tshwm sim los ntawm kev hloov pauv sab hauv, kev cuam tshuam hluav taws xob hluav taws xob, thiab lwm yam hauv cov cuab yeej siv suab. Kev ntsuas hluav taws xob ntau dhau yuav ncaj qha rau cov hluav taws xob hauv lub pob ntseg sab hauv lub mloog pob ntseg, ua rau lawv swb. Diodes have nonlinear characteristics that can suppress the amplitude of transient voltages to a certain extent, thereby protecting headphones from damage.
Txhim kho kev ntseeg tau
Los ntawm kev txwv tam sim no thiab tiv thaiv lub mloog pob ntseg los ntawm ntau dhau thiab hloov voltage puas tsuaj, diodes tuaj yeem txhim kho kev ntseeg tau ntawm lub mloog pob ntseg. Thaum muaj ntev -}}} siv, lub mloog pob ntseg muaj peev xwm tswj tau ruaj khov xws li kev hloov pauv tshiab lossis kev hloov pauv tam sim no lossis hloov hluav taws xob.
4, xaiv thiab application ntawm dodes
Thaum xaiv diodes rau lub mloog pob ntseg, nws yog ib qho tsim nyog los xav txog qhov tsis xws li lawv cov hluav taws xob hluav taws xob, nyob twj ywm tam sim no, thiab rov qab lub sijhawm rov qab los. Cov kev txwv no yuav tsum tau txiav txim siab raws li cov kev cai thiab kev ua haujlwm ib puag ncig ntawm lub mloog pob ntseg. Piv txwv li, rau lub mloog pob ntseg uas yuav tsum tau walland siab voltage, diodes nrog ntau dua rated voltage yuav tsum tau xaiv; Rau lub mloog pob ntseg uas xav tau los tiv thaiv kom siab, diodes nrog cov kev ntsuas siab dua uas yuav tsum tau xaiv.
Thaum ua ntawv thov diodes, nws yog ib qho tseem ceeb kom them sai sai rau lawv txoj kev sib txuas. Feem ntau, diodes yuav tsum tau txuas nyob rau hauv cov koob nyob rau ntawm lub hwj chim ntawm lub pob ntseg ntawm lawv tuaj yeem txwv qhov kev hla dhau lub pob ntseg. Ib qho ntxiv, kev saib xyuas yuav tsum tau them rau cov cua sov dissipation ntawm dodes. Vim yog cov cua sov tsim los ntawm kev ua haujlwm thaum lub sijhawm ua haujlwm, cov cua sov tsis zoo yuav ua rau txo qis hauv cov kev ua tau zoo lossis kev puas tsuaj. Yog li ntawd, thaum tsim lub ntsej muag circuits, txoj hauj lwm ntawm dodes yuav tsum tau npaj tsim nyog thiab tsim cua sov dissipation ntsuas yuav tsum tau ua.
