Dab tsi yog kev siv ntawm dodes?

1, Rectification Function: hloov dua siab tshiab los ntawm AC rau DC
Ib qho ntawm cov khoom siv yooj yim tshaj plaws thiab dav siv cov ntawv thov ntawm dodes yog raws li rectifiers. Nyob rau hauv lub zog hluav taws xob, hloov pauv tam sim no (AC) yog cov khoom siv hluav taws xob feem ntau, xav tau cov khoom siv thaum ntxov (DC) kom muab lub zog. DAIV Rectifier siv cov yam ntxwv ntawm nws dodes ua nyob rau tom ntej kev tsis ncaj ncees thiab txiav nyob rau hauv rov qab bias los hloov lwm txoj kev hloov tshiab tam sim no. Los ntawm kev sib txuas ntau yam diodes hauv series lossis txuas ntxiv lim kev ruaj khov tuaj yeem txhim kho txuas ntxiv, muab lub zog hluav taws xob ntxiv rau cov hluav taws xob hluav taws xob.
2, Nrhiav tau thiab Demodulation: Tus yuam sij rau kev sib txuas lus wireless
Hauv kev sib txuas lus ntawm wireless, diodes tseem ua lub luag haujlwm tseem ceeb. Hauv cov xov tooj cua thaum ntxov, donges tau siv ua cov ntsuas pom kom rho tawm cov cim kaw suab los ntawm cov xov tooj cua ntsuas kev nqa cov ntaub ntawv. Tus txheej txheem no zoo ib yam li rectification, tab sis tsom xam ntau dua ntawm cais tsawg - zaus- cov cim zaus. Nrog rau kev txhim kho ntawm kev thev naus laus zis, txawm hais tias cov txheej txheem sib xyaw ua ke ntau ntxiv hauv cov ntsiab lus sib txuas lus tseem ceeb hauv kev nkag siab rau kev nkag siab txog kev sib txuas lus kev sib txuas lus ntxiv.
3, Voltage stabilization thiab amplitude txwv: stabilizers rau kev tiv thaiv cov voj voog
Diodes tseem tuaj yeem siv los tsim cov kev cai voltage thiab txwv cov khoom siv hluav taws xob, kom ua haujlwm tau zoo txawm tias nyob rau hauv cov kev sib tw ntawm voltage hloov pauv. Zener Diodes (tseem hu ua Zener Thaum cov tswv yim voltage tshaj nws qhov kev rhuav tshem hluav taws xob, cov diode nqus tau ntau dhau tam sim no los tswj hwm qhov ruaj khov ntawm cov zis hluav taws xob. Cov xeeb ceem no ua rau cov kev ntsuas hluav taws xob nrog ib qho tseem ceeb hauv cov hluav taws xob hluav taws xob, tiv thaiv cov khoom siv hluav taws xob ntxiv los ntawm kev sib txuas hluav taws xob. Qhov kev txwv Circuit Court siv cov NonLinear tus yam ntxwv ntawm diodes kom txwv qhov siab tshaj plaws thiab tiv thaiv kev sib tw los ntawm cov khoom siv hluav taws xob ua kom puas tsuaj.
4, Hloov thiab Logic Cov Haujlwm: Lub Hauv Paus Ntawm Lub Ntiaj Teb Digital
Hauv cov kev ncig digital, donges ua haujlwm ua hloov cov ntsiab thiab yog lub hauv paus rau kev siv cov haujlwm ntsuas. Los ntawm kev tswj cov conduction thiab txiav cov xeev ntawm diodes, ua kom muaj peev xwm ua tiav, xws li thiab rooj vag, tsis yog rooj vag, thiab lwm yam). Cov laj thawj logic yog cov chav tseem ceeb uas ua rau cov khoom siv digital xws li cov txheej txheem computer thiab cov microcontrollers. Nrog kev nce qib ntawm cov thev naus laus zis thev naus laus zis, txawm hais tias lub hauv paus kev hloov pauv (tshwj xeeb yog lub hauv paus rau kev nkag siab digital logic thiab digital system tsim.
5, Optoelectronic daim ntaub ntawv: photododes thiab coj
Daim ntawv thov ntawm diodes nyob rau hauv daim teb optoelectronic kuj tseem tsis tseem ceeb. Photodiodes yog cov khoom siv uas tuaj yeem hloov lub teeb pom kev hauv cov cim hluav taws xob thiab tau siv dav hauv cov teeb pom kev zoo, kev sib txuas lus kho qhov muag, thiab cov duab ntsuas. Thaum lub teeb ci ntsa iab rau ntawm lub photodiode, photon Zog zoo hloov hluav taws xob hauv cov ntawv sau ua haujlwm, tsim kev hloov pauv ntawm lub teeb rau hluav taws xob. Ntawm qhov tsis sib xws, lub teeb - emsting diodes (leds) siv cov khoom tseem ceeb hauv kev teeb tsa tam sim no, tso duab thev naus laus zis, thiab teeb liab qhia. LED, nrog nws cov effecticiency, txuag hluav taws xob, thiab maj mam hloov cov yam ntxwv ua thiab ua kev tawm tsam ntawm lub teeb pom kev zoo thev naus laus zis.
6, lwm cov ntawv thov tshwj xeeb
Ntxiv nrog rau cov ntawv thov tseem ceeb tau hais los saum no,} Cov Hluav Taws Xob Hluav Taws Xob Zoo Tshaj Plaws, nrog lawv cov hluav taws xob tshwj xeeb} Cov Hluav Taws Xob Cov Hluav Taws Xob teb.
