Yuav ua li cas siv diodes los daws cov teeb meem rov qab tam sim no hauv cov khoom lag luam hluav taws xob?
Tso lus
1, ua rau thiab muaj kev phom sij ntawm kev rov qab tam sim no
Qhov ua rau kom rov qab tam sim no
Lub Generation ntawm rov qab tam sim no yog los ntawm ob qho xwm txheej hauv qab no:
Rov qab fais fab kev twb kev txuas: Lub polarity ntawm lub zog hluav taws xob yog thim vim yog cov neeg siv ua tsis raug lossis lub zog ua tsis tau.
Inductive thauj khoom siv hluav taws xob: Thaum lub zog hluav taws xob xws li lub cev muaj zog thiab lub zog khaws cia, lub zog khaws cia hauv lub zog hluav taws xob rov qab los ntawm kev ua haujlwm ntawm tus kheej.
Cov phom sij ntawm rov qab tam sim no
Cov kev puas tsuaj tiv thaiv: kev thim rov qab tej zaum yuav rhiab cov khoom sib txawv xws li diodes thiab transisors, ua rau muaj kev sib tw luv luv lossis qhib Circuit Court hauv Circuit Court.
Cov ntaub ntawv poob: hauv cov cuab yeej cia, rov qab tam sim no yuav ua rau cov khoom sib dhos, ua rau cov ntaub ntawv poob.
Kev Nyab Xeeb Kev Nyab Xeeb: Rov qab ntau dhau lawm yuav ua rau muaj kev pheej hmoo ntawm hluav taws lossis hluav taws xob.
2, lub hauv paus ntsiab lus ntawm kev siv dodes los daws cov teeb meem tam sim no
Unidirectional conduction cov yam ntxwv
Cov yam ntxwv tseem ceeb ntawm Diode yog unidirectional conduction, uas tso cai rau tam sim no kom ntws mus rau hauv ntej kev coj thiab txiav tawm hauv kev taw qhia rov qab. Cov yeeb yaj kiab no ua rau nws xaiv qhov zoo tshaj plaws rau kev rov qab cov kev txuas thiab rov qab tam sim no supression.
Kev Tshawb Fawb Kom Ceev
Lub caij cooj thiab txiav tawm ntawm lub sij hawm diodes yog luv heev (feem ntau tuaj yeem teb sai sai los thim rov qab thiab zam kev puas tsuaj rau Circuit Court.
Tsawg tus nqi thiab kev ntseeg siab
Cov txheej txheem sib raug zoo Diode raug ua kom paub tab, raug nqi-}}}}} kev ua haujlwm zoo heev hauv cov khoom lag luam electronics.
3, Daim ntawv thov ntawm dodes nyob rau hauv rov qab kev tiv thaiv tam sim no
Anti Rov Qab Kev Tiv Thaiv Kev Tiv Thaiv
Circuit Tsim Tsim: Txuas Diode (xws li 1n4001) hauv cov lus ntawm lub zog cov tswv yim davhlau ya nyob twg. Thaum lub zog polarity muaj tseeb, tus devo ua thiab Circuit Court ua haujlwm ib txwm muaj; 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.
Txhim Kho Rau Lub Tswv Yim:
Tsis tshua muaj hluav taws xob tsim: schottky diodes (xws li 1n5819) tau xaiv, nrog rau pem hauv ntej Voltage poob ntawm tsuas 0.5v, uas tuaj yeem txo kev siv zog.
Kev tsim qauv zoo tshaj plaws: parallel ntau cov diodes nyob rau hauv qhov tseem ceeb circuees los txhim kho kev ua txhaum kev ua txhaum.
Ntaub Ntawv Tshawb Xyuas:
Hauv kev tsim ntawm USB cov chaw chargers, 1N5819 DIODE tau txuas nrog hauv cov hluav taws xob rov qab los ntawm cov neeg siv kev siv hluav taws xob.
Rov Qab Tam Sim No
Kev Tsim Circuit Court: Txuas cov Diode (xws li 1n4148) nyob rau hauv parallel ntawm ob xaus ntawm inductive thauj. Thaum lub nra tau siv tawm, daim dikas muab txoj kev tam sim no, noj lub zog khaws cia hauv cov kauj, thiab tsim kho lub zog electromotive.
Txhim Kho Rau Lub Tswv Yim:
Kev rov qab nrawm dua: Xaiv cov dailes nrog lub sijhawm rov qab them rov qab (TRR), xws li kev rov qab nrawm dua ntawm kev thim rov qab.
Cov ntaub ntawv cua sov dissipation: hauv qhov siab -}} Lub Hwj Chim Cov Kev Siv, nws yog ib qho tsim nyog los xav txog cov cua sov dissipation ntawm dodees kom tsis txhob overheating thiab puas.
Ntaub Ntawv Tshawb Xyuas:
Hauv DC lub cev tsav tsheb hluav taws xob, lub voj voog frd diode yog siv los ua kom zoo rau lub zog hluav taws xob rov qab los, tiv thaiv kev tsav tsheb los ntawm kev puas tsuaj.
Kev tiv thaiv Circuit Court
Circuit Tsim Tsim: Txuas TVs diodes (Transient voltage suppressors) hauv parallel rau cov paib tseem ceeb lossis cov kab hluav taws xob. Thaum lub voltage ntau dua nws qhov kev sib cav tau ntau dua, cov TVs sai sai ua, tso tawm lub zog ua rau hauv av thiab tiv thaiv lub voj tom ntej.
Txhim Kho Rau Lub Tswv Yim:
Tsawg clamping voltage: Xaiv cov TVs dodes dodes nrog qis clamping voltage los txo cov kev cuam tshuam ntawm lub voj voos tom ntej.
Bidirectional tiv thaiv: Hauv AC circuits, Balirectional TVs dodes dodes yog siv los tiv thaiv cov kev tiv thaiv zoo thiab tsis zoo ib nrab mus.

Hauv USB interface tsim qauv ntawm cov xov tooj smartphones
4, Diode xaiv thiab txhim kho lub tswv yim
Qhov Tseem Ceeb Xaiv
Kev rov ua dua peak ntxiv voltage (VRRM): Qhov ntau tshaj plaws voltage uas ib qho diode tuaj yeem tiv taus, uas yuav tsum muaj ntau dua qhov kev thim rov qab ntau tshaj plaws uas tuaj yeem tshwm sim hauv Circuit Court.
Qhov nruab nrab rau pem hauv ntej rectified tam sim no (yog (AV)): Qhov nruab nrab tam sim no thaum twg ib qho Diode tab tom ua rau pem hauv ntej, uas yuav tsum muaj ntau dua qhov kev ua haujlwm ntau tshaj plaws hauv Circuitating.
Forward voltage (VF): Qhov ntsuas hluav taws xob thaum muaj kev coj ua hauv kev coj ua, thiab tus nqi tsim nyog yuav tsum tau xaiv raws li kev xav tau ntawm Circuit Court.
