Dab tsi yog qhov ua haujlwm ntawm tus qauv diode?

1, cov ntsiab lus tseem ceeb thiab ua haujlwm ntawm cov ntsiab cai ntawm cov qauv diodes
Cov qauv txheej txheem ib txwm xa mus rau cov cuab yeej semiconductor nrog unidirectional conductivity. Nws yog tsim los ntawm ib qho kev sib tw PN (tsim los ntawm kev sib cuag ntawm ib qho P- hom semiconductor), uas ua thaum lub zog nthuav dav thiab tam sim no tuaj yeem ntws los ntawm nws; Thaum rov qab voltage yog thov, lub pn kev sib tshuam yog txiav tawm thiab yuav luag tsis muaj tam sim no ntws. Qhov kev coj tsis zoo no yog qhov tseem ceeb tshaj plaws ntawm cov yam ntxwv ntawm diodes thiab lub hauv paus rau lawv txoj haujlwm hauv kev voj voog.
Tus ua haujlwm ua haujlwm ntawm diodes yog raws li cov qauv band thiab cov cab kuj xav ntawm cov semiconductors. Nyob rau hauv lub pn kev sib tshuam, ib qho kev ua kom zoo rau hauv hluav taws xob yog tsim vim muaj qhov sib txawv hauv cov kab hlau sib txawv ntawm P thiab cov cheeb tsam. Thaum cov voltage rau pem hauv ntej, lub tsim {{3} Nyob rau hauv hluav taws xob tsis muaj zog, cia cov neeg nqa khoom mus dhau los ntawm pn hlws ris thiab tsim ib qho tam sim no. Thaum rov qab voltage yog thov, lub tsim tsa {{5} Nyob rau hauv cov hluav taws xob txuas, ua rau muaj kev rov qab nrawm dua (hu ua thim rov qab tam sim no).
2, lub ntsiab ntawm cov qauv txheej txheem
Cov qauv txheej txheem dodes tuaj yeem faib rau ntau yam raws li lawv cov ntaub ntawv, qauv, thiab kev siv. Ntawm lawv, cov uas muaj xws li silicon diodes, German diodes, taw tes sib cuag diodes, nto moo sib cuag diodes, thiab lwm yam.
Silicon Diode: Ua los ntawm silicon li cov khoom siv, nws muaj kev rov qab siab dua tam sim no, thiab yog siv dav hauv siab {- zaus.
German Diode: ua los ntawm Germanium raws li cov khoom siv, nws muaj qhov ntxiv rov qab los tam sim no, tab sis ib qho kev haum rau qis {{- zaus.
Taw tes hu rau Diode: Nrog thaj chaw sib tshuam me me, nws yog qhov tsim nyog rau cov haujlwm xws li nrhiav kom paub thiab kho kom pom tseeb hauv qhov siab {{zaus.
Nto tiv toj Diode: Nrog thaj chaw sib tshuam loj, nws tuaj yeem tiv thaiv cov dej loj loj thiab haum rau hluav taws xob xws li cov kev cai hluav taws xob.
3, lub luag haujlwm ntawm cov qauv txheej txheem hauv cov voj voog
Lub luag haujlwm ntawm cov qauv txheej txheem hauv cov hluav taws xob yog muaj ntau yam sib txawv, suav nrog tab sis tsis txwv rau cov hauv qab no:
Rectification muaj nuj nqi: ib tug Diode tuaj yeem ua raws li lub rectifier ntawm AC lub zog thiab DC thauj khoom, hloov AC lub zog rau hauv DC lub zog. Nov yog ib qho ntawm cov kev siv yooj yim tshaj plaws ntawm diodes, siv ntau lub zog fais fab.
Kev Nrhiav Ua Haujlwm: Hauv xov tooj cua tau txais hluav taws xob, donges tuaj yeem ua raws li cov ntsuas pom los rho tawm cov teeb liab cov teeb liab. Qhov no yog ib feem tseem ceeb ntawm cov tshuab sib txuas lus wireless.
Voltage ruaj khov ua haujlwm: los ntawm kev siv cov kev sib txig tom qab dodees, tseem hu ua zenerlization detiodes Qhov no yog qhov tseem ceeb rau kev tiv thaiv lwm cov khoom hauv Circuit Court los ntawm kev sib pauv hluav taws xob.
Hloov ua haujlwm: Hauv cov khoom siv digital, donges tuaj yeem ua cov khoom hloov mus rau kev tswj hwm ntawm / tawm ntawm Circuit Court. Daim ntawv thov no siv Unidirectional kev coj ua ntawm diodes, tso cai rau cov Circuit Court coj los coj raws li voltage rau pem hauv ntej.
Kev ua haujlwm ntawm cov teeb meem ntawm cov teeb meem ntawm kev ua haujlwm zoo li cas (xws li cov kab ke tawm ntawm cov teeb meem Txawm li cas los xij, qhov txiaj ntsig amplification yog feem ntau tsis yog qhov tseem ceeb thiab txuag tau ua cov transistors.
4, thov cov piv txwv ntawm cov qauv dodes
Muaj ntau cov piv txwv ntawm cov ntawv thov ntawm cov qauv txheej txheem hauv cov hluav taws xob hluav taws xob. Ntawm no yog ob peb hom neeg ua piv txwv:
Rectifier Choj choj Circuit Court: Lub Rectifier Choj Circuita tsim ntawm plaub diodes, uas tuaj yeem hloov dua tshiab rau hauv qhov tam sim no thiab ua tiav ib nrab lub voj voog. Hom ntawm Circuit Court yog dav siv nyob rau ntau lub zog fais fab.
Voltage regulator lub hwj chim hluav taws xob muab khoom: ib qho hluav taws xob regulator lub zog hluav taws xob muab cov zis hluav taws xob thiab tiv thaiv lwm yam, thiab muaj peev xwm tswj tau cov khoom siv hluav taws xob thiab tiv thaiv lwm yam hauv cov hluav taws xob los ntawm kev sib hloov hluav taws xob.
Cov teeb liab ntes: Hauv xov tooj cua tau txais cov hluav taws xob, kev kuaj xyuas ntawm dendal cov teeb liab cov teeb liab, ua tiav cov teeb liab kev tos txais thiab rhuav tshem.
Logic Rooj vag Circuit Court: hauv cov kev sib tw digital, xws li thiab cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog lub rooj vag, lossis cov rooj vag, tsis yog rooj vag los cuag cov kev ua haujlwm thiab kev ua haujlwm digital.
