Yuav ua li cas diiodes ua haujlwm ua ke hauv kev sib txuas lus zoo tshaj plaws?

一, synergistic moolism ntawm diodes hauv teeb liab ua
1. Kev txwv thiab clamping ua haujlwm
Hauv kev sib txuas lus zoo tshaj plaws, donges muaj feem ntau siv los ua kom tsis txhob muaj teeb meem amplitude thiab tiv thaiv kev cuam tshuam rau overload distortion. Piv txwv li, hauv cov theem nrab zaus amplement ntawm qhov kev ntsuas qhov tau txais, ib qho kev sib txuas yog tsim los ntawm rov qab sib txuas ntawm ob dodes. Thaum cov phiajcim nkag tau ntau dua rau pem hauv ntej conduction voltage ntawm diode (clamping ua, clamping lub teeb liab nthuav dav hauv kev nyab xeeb. Cov tshuab no tuaj yeem tiv thaiv kev cuam tshuam tom qab tom ntej los ntawm cov teeb liab muaj zog thaum muaj teeb liab kev ncaj ncees.
2. Rectification thiab Kev Tshawb Nrhiav Ua Haujlwm
Dailes feem ntau siv nyob rau hauv kev sib txuas lus hauv kev sib txuas lus zoo tshaj plaws thiab ntes cov cim. Piv txwv li, hauv ib qho voltmeter nyob rau hauv lub suab thaj tsam, lub teeb liab tau hloov mus rau DC lub teeb liab los ntawm tus choj Rectifier Circuit Court. Thaum cov teeb liab tawm tswv yim yog qhov zoo ib nrab voj voog, qhov tam sim no ntws los ntawm Diode D1 rau lub ntsuas; Ntawm qhov tsis zoo ib nrab hlis, qhov tam sim no ntws los ntawm D2 rau lub ntsuas dej. Cov qauv no tshem tawm cov tsis ua yuam kev ntawm Diode thiab ua kom cov kab ntawm txoj kev ntsuas.
3. Kev kuaj pom thiab tuav
Hauv lub ncov mus kuaj pom kev ua haujlwm, cov kev ua haujlwm thiab ua haujlwm ua haujlwm ua haujlwm ua ke kom ua tiav kev paub tseeb thiab txij nkawm ntawm lub teeb liab peaks. Piv txwv li, thaum cov teeb liab tawm tswv yim yog qhov zoo, cov kev ua haujlwm ua haujlwm thiab diode follower, them sai sai them cov cim npe; Thaum cov teeb liab tawm tswv yim txo qis, cov diode hloov thiab lub capacitor tuav nws lub peak voltage. Qhov Circecth no tau siv dav hauv tsis siv neeg nce tswj (AGB), muab kev siv rau kev hloov kho ntxiv.
2, lub synergistic moolism ntawm diodes hauv kev tiv thaiv Circuit Court
1. Electrostatin (ESD) Kev Tiv Thaiv
Ntawm cov tswv yim ntawm kev sib txuas lus ntxiv amplifier, ib khub ntawm kev rov qab series dodes feem ntau txuas nrog thaum ntsuas qhov kev tiv thaiv Esd. Thaum cov phiajcim tawm tswv yim yog qhov qis dua qis dua li cov conduction voltage ntawm Diode, tus diode tsis muaj nuj nqi; Thaum cov lus qhia tshaj li ntawm cov conduction rau pem hauv ntej ntawm Diode, tus dide ua, kos cov paib qhia tawm hauv qhov hluav taws xob zoo. Cov tshuab no tuaj yeem tiv thaiv kev puas tsuaj rau lub tswv yim amplifier cov theem tshwm sim los ntawm kev tawm hluav taws xob.
2. Kev Tiv Thaiv Kev Tiv Thaiv
Ntawm lub zog muab kev sib txuas lus kawg ntawm kev sib txuas lus, Diode cov luam yog feem ntau siv rau kev tiv thaiv kev tiv thaiv. Piv txwv li, los ntawm kev sib txuas ntau cov dodes nyob rau hauv series, qhov siab tshaj plaws tam sim no los ntawm kev nyab xeeb nyob rau hauv ib qho kev nyab xeeb nyob rau hauv ib qho kev nyab xeeb ntawm txhua qhov hluav taws xob rau pem hauv ntej. Cov qauv no muaj peev xwm muab cov kev paub ruaj khov rau hauv qhov tsawg tsawg, tiv thaiv cov Circuit Court Board los ntawm kev cuam tshuam ntawm overvoltage.
3. Txuas ntxiv ntws thiab lub zog nqus tau
Nyob rau hauv inductive thauj khoom siv hluav taws xob, donges feem ntau siv rau kev ua kom dawb thiab nqus hluav taws xob. Piv txwv li, nyob rau hauv ib qho hloov chaw hluav taws xob, thaum lub tshuab hloov chaw tau tua, lub zog hluav taws xob uas tau tso tam sim no thiab ua kom muaj zog hluav taws xob. Lub freewheeling Diode tiv thaiv lub transcuit Court ntawm kev puas tsuaj los ntawm kev tso cai tam sim no, tiv thaiv cov teeb meem ntawm kev them nqi hla nrog lub inductor thauj.
3, diode synergy mechanism nyob rau hauv dynamic nce kev tswj hwm
1. Daim ntawv thov ntawm PIN diode hauv AGC
Tus Pin Diodes muaj qhov tseem ceeb hauv kev tswj hwm kev tswj hwm vim lawv cov qauv txheej txheem txheej txheem. Nws cov microwave conduction yog kwv yees li ua ntu zus rau DC tam sim no, thiab nws cov Series tiv thaiv yog me, ua rau poob qis. Nyob rau hauv AGC cov voj voog, tus lej Pin feem ntau siv los ua cov resistic ua tiav hauv ntu txuas ntawm Cleupling Coupren ntawm Amplifiers. Thaum qhov siab - zaus kos npe nce, nws qhov sib npaug ntawm kev nce ntxiv, thiab cov kev cuam tshuam shuntant, yog li txo qhov nce ntawm lub amplifier.
2. Forward txoj kev tswj thiab rov qab tswj txoj kev
Nyob rau hauv AGC systems, diodes feem ntau siv los siv rau pem hauv ntej thiab rov qab tswj txoj kev. Txoj kev tswj hwm nraim txo qhov nce los ntawm kev hloov cov kev ua haujlwm tam sim no ntawm lub cuab yeej tam sim no ntawm lub sijhawm luv luv- Circuit Court tam sim no Amplemificate Factor. Qhov kev tswj hwm rov qab txo qhov nce los ntawm kev hloov cov haujlwm ua haujlwm ntawm lub siab tseem ceeb, txo qis nws cov tswv yim impedance. Ob txoj kev ua tiav kev hloov kho dua tshiab tau hloov los ntawm kev sib koom tes ua haujlwm ntawm diodes thiab amplififiers.
3. Nce tswj Circuit Court
Nyob rau hauv ncua Aphc voj voog, dodes ua haujlwm ua ke nrog detectors nrog dcifiers kom ua tiav kev ncua sij hawm tswj tau. Piv txwv li, kev nrhiav cov zis voltage yog thov rau qhov zoo ntawm Diode, thiab tsuas yog thaum muaj hluav taws xob voltage ntau dua li cov ntaub ntawv ntsuas, tso cai rau AGC tswj voltage ua rau lub amplifier. Cov txheej txheem no tuaj yeem zam qhov tsis raug ntawm lub system AGC thaum lub cim me me thiab txhim kho kev ruaj ntseg ntawm lub system.
4, Daim Ntawv Thov Raug Raug Zoo thiab Kev Koom Tes Ua Haujlwm
1. AGC system nyob rau hauv qhov dav hloov kho tus tau txais
Nyob rau hauv amplitudation tau txais, AGC system ua tiav Automatic tau kev hloov kho los ntawm kev ua haujlwm ua haujlwm ntawm diodes thiab amplifas. Ob leeg siab - zaus} ampl frequ frequ frequ and and and and and and and ampl ampl ingfiers thiab lawv tau txais kev tswj hwm los ntawm AGC tswj voltage. Cov zis tawm ntawm cov theem nrab zaus amplifier tau xa mus rau ib sab channel ntes ntawm ib sab, thiab yog thov rau lwm lub hnab ntawv ntsuas ncov ntawm sab nraud. Lub DC voltage protortional rau cov cab kuj yog demodulated thiab piv nrog siv voltage, thiab tom qab ntawd AGC tswj voltage yog tau los ntawm DC amplifier.
2. Optical pem hauv ntej -}} xaus rau kev sib txuas lus fiber optic kev sib txuas lus tau txais
Nyob rau hauv cov ntawv sib txuas lus fiber ntau, photododes thiab preamlifiers tsim lub optical optical pem hauv ntej {kawg, uas hloov kho kho qhov muag rau hauv cov cim hluav taws xob. Photodiodes hloov lub teeb rau hauv photocrifent rau hauv photocrify hloov ntaub photocurrifent rau volfage thiab ua kom nrov rau lub teeb liab. Thaum lub sijhawm ua haujlwm no, diodes ua haujlwm ntawm cov duab muaj nuj nqi los ntawm cov duab muaj nuj nqi los ntawm kev sib xyaw ua ke, ua haujlwm nrog cov khoom siv hluav taws xob kom ntseeg tau tias thiab kev sib kis.
3. Suab nrov hauv TV Antenna Amplifas
Hauv TV astenna amplifas, diodes thiab amplifiient ua haujlwm ua ke kom ua tau lub suab nrov transpress thiab teeb liab txhim kho. Piv txwv li, los ntawm kev xaiv tsawg- party tsis tau txais cov kab ke, thiab lub teeb liab} {3} {{3} {{3} {{3} {} Cov suab nrov tuaj yeem hloov kho. Lub Diod ua si lub luag haujlwm hauv teeb liab kev txwv thiab lub suab nrov thaum lub sijhawm ua haujlwm no, kom ua haujlwm ruaj khov ntawm lub siab zoo.
