Puas yog lub diode AC lossis DC?

1, Lub hauv paus ntsiab lus ua haujlwm thiab cov yam ntxwv ntawm diodes
Lub hauv paus ntawm lub diode yog nyob rau hauv PN hlws ris, uas yog lub cheeb tsam interface tsim los ntawm kev sib cuag ntawm P-hom semiconductor (nplua nuj nyob rau hauv qhov) thiab N-hom semiconductor (nplua nuj nyob rau hauv electrons). Cov qauv no endows lub diode nrog tshwj xeeb unidirectional conductivity: thaum rau pem hauv ntej biased (anode rau zoo muaj peev xwm, cathode rau tsis zoo tej zaum), lub diode conducts, cia tam sim no mus dhau los; Thaum rov qab biased, lub diode yog muab tua thiab yuav luag tsis-conductive. Cov yam ntxwv no ua rau diodes yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.
2, Daim ntawv thov ntawm diodes nyob rau hauv alternating tam sim no thiab ncaj qha tam sim no
1. Daim ntawv thov ntawm Direct Current (DC)
Hauv DC circuits, diodes feem ntau yog siv rau kev kho thiab kev ruaj ntseg voltage. Rectification yog hais txog cov txheej txheem ntawm kev hloov pauv tam sim no rau hauv cov tam sim no ncaj qha, thiab diodes yog cov khoom tseem ceeb hauv cov txheej txheem no. Los ntawm kev tswj cov kev coj ua thiab kev txiav tawm ntawm diodes, qhov zoo thiab qhov tsis zoo ib nrab ntawm AC lub zog tuaj yeem khaws cia thiab txiav tawm raws, yog li ua tiav kev hloov pauv ntawm AC mus rau DC. Tsis tas li ntawd, diodes feem ntau siv nyob rau hauv cov kev cai voltage circuits kom stabilize cov zis voltage thiab tiv thaiv lwm yam nyob rau hauv lub Circuit Court los ntawm voltage fluctuations los ntawm kev kho lawv cov kev khiav hauj lwm taw tes.
2. Kev siv hluav taws xob hloov hluav taws xob (AC)
Hauv AC circuits, diodes kuj ua lub luag haujlwm tseem ceeb, tab sis lawv feem ntau tshwm sim nyob rau hauv daim ntawv ntawm cov keyboards, detectors, modulations, thiab lwm yam. Piv txwv li, nyob rau hauv ib tug switching Circuit Court, ib tug diode ua hauj lwm pab raws li ib tug hloov lub caij kom sai hloov nws conduction thiab txiav tawm lub xeev, ua tiav cov kev xaiv los yog thaiv ntawm AC teeb liab. Hauv kev kuaj xyuas Circuit Court, diodes yog siv los rho tawm cov ntaub ntawv tseem ceeb los ntawm cov teeb liab modulated, uas yog qhov tseem ceeb hauv cov khoom siv xws li xov tooj cua receivers. Tsis tas li ntawd, diodes kuj tseem siv rau hauv kev hloov pauv hauv Circuit Court txhawm rau thauj cov teeb liab tsawg zaus mus rau cov neeg nqa khoom siab, ua kom cov teeb liab xa mus thiab ua tiav.
3, Qhov tseem ceeb ntawm diodes nyob rau hauv niaj hnub Electronic Technology
Diodes tsis yog tsuas yog tus choj ntawm AC thiab DC lub zog hloov pauv, tab sis kuj yog lub hauv paus ntawm kev txhim kho hluav taws xob niaj hnub siv tshuab. Los ntawm thawj zaug rectifiers thiab voltage regulators, mus rau tom qab transistor xov tooj cua thiab TVs, mus rau niaj hnub integrated circuits, computers, kev sib txuas lus cov khoom, thiab lwm yam., diodes tau tsav cov kev loj hlob ntawm hluav taws xob technology nrog lawv cov cim kev ua tau zoo.
Nyob rau hauv lub tshav pob ntawm kev sib txuas, txawm hais tias diodes tau hloov los ntawm ntau cov transistors thiab kev sib xyaw ua ke, lawv cov ntsiab lus tseem ceeb thiab cov yam ntxwv ntawm unidirectional conductivity tseem yog lub hauv paus ntawm cov khoom siv hluav taws xob niaj hnub no. Tsis tas li ntawd, nrog rau kev tsim cov ntaub ntawv tshiab thiab cov txheej txheem, diodes tau tsim kho tas li, xws li Schottky diodes, lub teeb-emitting diodes (LEDs), thiab lwm yam. Lawv tau pom muaj peev xwm zoo rau kev siv hauv kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, teeb pom kev zoo, thiab lwm yam. teb.
