Lub luag haujlwm ntawm lub capacitor nyob rau hauv ib leeg Coupling Circuit Court?

Hav muaj! Raws li tus neeg xa khoom siv hluav taws xob, Kuv tau nug ntau txog lub capacitor nyob rau hauv ib co co} Yog li, Kuv xav tias kuv yuav yooj yim kom nkag siab.

Cia peb pib nrog cov hauv paus . Lub capacitor yog qhov sib txuas hluav taws xob hauv ib lub zog hluav taws xob, nws ua qee qhov tseem ceeb uas yog qhov tseem ceeb uas yog qhov tseem ceeb tshaj plaws.}

Thaiv DC thiab dhau AC

Ib qho ntawm cov haujlwm tseem ceeb ntawm capacitor nyob rau hauv ib tug coupling Circuit Court tam sim no uas ntws mus rau ib qho tam sim no, zoo li cov hluav taws xob tsis tu ncua, zoo li hluav taws xob hauv peb lub tsev.

Capacitors ua haujlwm raws li lub ntsiab lus ntawm kev them nyiaj thiab tsis muaj kev them nyiaj rau DC rho tawm raws li qhov hluav taws xob ntawm AC teeb liab hloov {}} Qhov no tso cai rau PS concitically ua kom zoo los ntawm cov capacitor {}}

Piv txwv li, hauv lub suab ampliCuit Court, koj tsis xav tau lub DC Indepage los ntawm ib theem ntawm lub ntsuas hluav taws xob tuaj yeem ua haujlwm ntawm lub dc kev ywj pheej nrog nws tus kheej kom haum DC biased .

Kev Cuam Tshuam Sib Tw

Lwm qhov tseem ceeb ntawm lub capacitor nyob rau hauv kev txuas ntawm Circuit Court yog qhov ntsuas ntawm ntau npaum li cas cov ntws los ntawm ntau npaum li cas ntau qhov no yog qhov twg impedance txuam los hauv .

Peev xwm muaj lub vaj tse hu ua Capacitive ((x _} Yog (f)} tus nqi ntawm capacitance, peb tuaj yeem kho cov peev xwm ntsuas hluav taws xob kom phim lub impedance ntawm qhov chaw thiab load .

Cia peb hais tias peb muaj lub hauv paus cuam tshuam nrog cov zis siv hluav taws xob (RF) Kev ntsuas kev ntsuas thiab txais tos hluav taws xob .

Kev lim

Capacitors kuj ua raws li cov ntxaij lim dej {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}

Tsawg kawg ntawm cov lim dej tso cai rau cov paib uas tsis muaj peev xwm ua kom muaj peev xwm ua kom muaj zog - Ntau dua ntawm lub teeb liab tau poob qis - zaus yog shunted mus rau hauv av .

Hloov siab, lub lim dej siab - PASS lim tso kom loj hlob - zaus ua kom dhau lub cev ntawm lub taub lim dej .

Band - Dhau Lim, raws li lub npe qhia, cia qee yam ntawm cov lim dej yog qhov tseem ceeb ntawm kev tsim cov band thiab tsis lees paub qhov tsis xav tau zaus.

 

 

Peb Lub Peev Xwm Khoom

Ntawm peb lub tuam txhab, peb muab ntau lub siab muaj peev xwm - qhov muaj peev xwm muaj peev xwm muaj peev xwm tsim nyog rau co coupling circuits {}} piv txwv li, pebAsmj ac filter fais fab condenseryog tsim los tuav High - Fais fab ac app thov {{1} Nws muaj peev xwm siv hluav taws xob zoo thiab muaj peev xwm siv hluav taws xob zoo thiab muaj teeb liab yog qhov tseem ceeb.

Peb liKev sib xyaw ua ke cov khoom siv khoom sivPuas yog lwm txoj kev xaiv zoo . nws ua ke ntau yam kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua kom zoo ntawm kev txhim kho hluav taws xob los ntawm kev ua kom muaj zog hloov kho hluav taws xob zoo siab thiab txo lub zog ua kom muaj zog.

Yog tias koj cuam tshuam nrog cov teeb meem harmonic hauv koj txoj kev txuas Circuit Court, pebNtse Harmonic Sai Kev Sib Koom Tes Hluav Taws Xobyog txoj kev mus . nws tuaj yeem txhim kho kev ua kom zoo thiab txhim kho lub zog ua haujlwm, uas yog cov haujlwm tsim nyog ntawm ntau lub tshuab hluav taws xob.

 

 

Vim li cas thiaj xaiv peb lub peev xwm capacitans?

Peb nkag siab tias xaiv cov captitor txoj cai rau koj cov ntaub ntawv zoo tshaj plaws rau koj cov ntaub ntawv tshwj xeeb, ua rau peb muaj kev ntseeg tau zoo thiab ntev -}}}

Peb tseem muab nqi sib tw, yog li koj tuaj yeem tau txais tus nqi zoo tshaj plaws rau koj cov nyiaj {}}}}}}} Koj puas muaj capacitor loj rau koj .

Tiv Tauj Peb Rau Kev Ua Haujlwm

Yog tias koj txaus siab rau peb cov khoom siv capinitor lossis muaj cov lus nug txog lawv cov kev sib tham zoo rau koj, thiab peb tau pib ua haujlwm rau koj {{4 4}}
