Yuav ua li cas tsim cov kev tiv thaiv kev tiv thaiv kev tiv thaiv los txhim kho kev nyab xeeb ntawm cov khoom siv hauv tsev neeg?
Tso lus
1, cov tub ntxhais muaj nuj nqi ntawm Diode kev tiv thaiv Circuit Court
Anti Rov Qab Kev Tiv Thaiv Kev Tiv Thaiv
Rov qab fais fab kev sib txuas yog ib hom kev ua txhaum hauv cov khoom ua haujlwm hauv tsev, uas tuaj yeem ua rau Circuit Court cov khoom, sib xyaw ua ke, thiab hluav taws kub. Diode Anti Plain Kev Tiv Thaiv Circuit Charcuit Chainment Siv Series Los Tiv Thaiv Rov Qab ntws tawm los ntawm kev siv lawv cov kev coj ua. Piv txwv li, thaum ib qho diode txuas rau hauv cov lus qhia thaum kawg ntawm DC cov khoom siv hluav taws xob, thiab lub cev ntas yog qhov tseeb, tus lej ntawm Circuit Course; Thaum lub zog hluav taws xob tau thim rov qab, tsim cov diode txiav tawm, tsim kev qhib Circuit Court los tiv thaiv qhov tom ntej.
Rov qab tiv thaiv tam sim no
Hauv cov ntawv thov xws li lub cev muaj zog tsav thiab coj teeb pom kev zoo, rov qab tam sim no tej zaum yuav ua rau lub rhiab. Los ntawm parallel thim rov qab kev tiv thaiv diodes, nws tuaj yeem ua kom ntseeg tau tias tam sim no tsuas ntws hauv kev taw qhia tom ntej. Piv txwv li, hauv kev LED Circuit Court, 1N4001 Diode txuas nrog hauv parallel. Thaum cov thaub qab voltage ntau dua 50v, cov dikas tawg cia thiab ua, bypassing rov qab tam sim no thiab tiv thaiv tus coj los ntawm kev puas tsuaj.
Clampage Clamp
Qhov kev ntsuas hluav taws xob clamp txwv txwv qhov hluav taws xob tsis pub dhau txoj kev nyab xeeb los ntawm dodes. Thaum cov tswv yim voltage tshaj rau pem hauv ntej hluav taws xob ntawm Diode, tus diode ua thiab diverts cov ntau tshaj plaws. Piv txwv li, ib qho hluav taws xob regulator diode txuas rau hauv parallel ntawm lub tswv yim xaus ntawm DC cov khoom siv fais fab kawg. Thaum cov tswv yim voltage tshaj nws qhov kev sib cav sib ntau dua, clamping ua, clamping lub voltage ntawm cov nqi txuas thiab tiv thaiv cov kab txuas ntxiv los ntawm kev puas tsuaj.
Voltain Soltression
Cov kev hloov pauv hloov pauv (xws li xob laim, hloov haujlwm) yuav ua rau kev puas tsuaj rau Circuit Court. TVS DIODES DIEST (Transient voltage suppressors) muaj cov yam ntxwv ntawm cov lus teb ceev, uas tuaj yeem nqus tau lub zog hloov pauv. Piv txwv li, thaum lub TV bidireectional diode ntawm cov lus qhia ntawm lub zog, tso tawm lub zog hluav taws xob xaus rau hauv av thiab kev tiv thaiv lub zog tom qab.
2, Cov kev tiv thaiv Diode raug cov qauv kev tiv thaiv
Diode Series Anti Plaj Kev Tiv Thaiv
Qhov kev sib tw hluav taws xob ua tiav kev tiv thaiv los ntawm kev tiv thaiv rov qab los ntawm kev sib txuas nrog cov diode hauv cov lus ntawm lub zog cov tswv yim davhlau ya nyob twg. Qhov zoo yog cov qauv yooj yim thiab tus nqi qis, tab sis muaj kev ntsuas hluav taws xob ntawm 0.7v, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm qis}} voltage mov circuits. Txhawm rau kom txo tau hluav taws xob noj, muaj voltage qis suv schottky diodes yuav siv tau.
Diode parallel anti tiv thaiv
Kev tiv thaiv rov qab los tiv thaiv tau tiav los ntawm kev ua kom sib haum thiab rov qab ua ke. Thaum lub zog hluav taws xob tau thim rov qab, cov Diode ua, clamping lub voltage ntawm 0.7v, tsim qhov siab tam sim no uas ua rau lub fuse los ua haujlwm thiab txiav tawm ntawm Circuit Court. Cov Circuit Court no tuaj yeem tiv thaiv lub zog hluav taws xob rau cov nqi tom qab, tab sis yuav tsum muaj kev tso nyiaj ntxiv.
Rectific Choj Hom Anti Plaj Kev Tiv Thaiv
Kev sib txuas ntawm cov ntsuas hluav taws xob mus rau hauv qhov hluav taws xob ua kom muaj kev ua haujlwm ib txwm tsis hais txog cov polarity ntawm lub zog. Qhov tsis zoo ntawm Circuit Court yog tias qhov hluav taws xob poob hla cov diode noj lub zog, uas yog ob zaug lub zog tau noj ntawm series series.
TVs Diode Kev Tiv Thaiv Circuit Court
TVS DIODES tau dav siv rau kev tiv thaiv kev tiv thaiv hauv DC cov khoom siv fais fab, thiab kab teeb meem. Piv txwv li, hauv USB interface Circuitfation, ib qho TV unidirectional diode d
3, Xaiv cov kev xaiv thiab cov tswv yim ntawm cov tswv yim ntawm dodes
Qhov Tseem Ceeb Xaiv
Thaum tsim cov kev tiv thaiv DIode kev tiv thaiv, cov kab hauv qab no yuav tsum tau txiav txim siab:
Rov ua dua peak ntxiv voltage (VRRM): qhov siab tshaj plaws rov qab uas cov diode tuaj yeem tiv taus.
Qhov nruab nrab rau pem hauv ntej rectified tam sim no (yog (AV)): Qhov nruab nrab tam sim no thaum ib qho diode tab tom ua hauv kev taw qhia tom ntej.
Forward voltage (VF): Qhov hluav taws xob tso tawm thaum ib daim diode tab tom ua rau hauv ntej.
Rov qab lub sijhawm rov qab rov qab (TRR): Lub sijhawm rov qab los ntawm Diode los ntawm kev ua kom tiav los txiav.
Daim Ntawv Thov Kev Thov
Xaiv diodes raws li kev ua haujlwm volthage thiab tam sim no ntawm Circuit Court: Nco ntsoov tias VRRM thiab yog tias (AV) ntawm DIODE ua raws li kev ua raws li Circuit Court.
Txhim kho cov txheej txheem Circuit Court: txo Parasitic inductance ntawm diodes thiab lwm yam kev siv, thiab txhim kho kev teb kom ceev.
Xav txog cov teeb meem ua kom sov: Cov ntaub ntawv thov siab tam sim no, diodes yuav tsim cov cua sov, thiab cov dej sov yuav tsum tsim.
