Cov Upution impedance cuam tshuam rau kev ua tau zoo ntawm lub voltage qis dua tshiab series?

Hav muaj! Raws li tus xa khoom ntawm cov lus nug tsis tshua muaj kev hloov pauv ntawm kev ua tau zoo rau koj kom tsis txhob muaj kev cuam tshuam rau koj rau kev nkag siab uas yooj yim to taub.

Thawj zaug tawm, cia tham txog dab tsi tsim tawm impedance yog qhov ua kom muaj zog ntxiv rau thaum koj sim ua kom muaj zog ntxiv rau cov khoom siv tau tam sim no rau lub nra yam tsis muaj qhov tseem ceeb poob hauv voltage, thaum lub zog siab tshaj tawm txhais tau tias qhov hluav taws xob ntawm lub nra yuav poob ntau dua li qhov tam sim no nce ntxiv.

Tam sim no, cia peb nkag mus ua kom cov zis tawm cuam tshuam rau kev ua tau zoo ntawm kev siv voltage qis dua .

Kev cai voltage

Ib qho tseem ceeb tshaj plaws ntawm kev siv voltage qis dua yog nws lub peev xwm los tswj cov kev hloov pauv hloov pauv, thaum lub tshuab hluav taws xob txuas nrog qhov no.

 

 

Cia peb hais tias koj muaj lub tshuab hloov pauv nrog cov khoom siv siab tshaj plaws {}}}}}}}} Thaum twg cov khoom siv hluav taws xob loj heev tuaj yeem tswj cov khoom txaus ntshai heev voltage even when the load current changes. This is because there is less internal voltage drop, so more of the voltage from the switcher reaches the load.

Piv txwv li, yog tias koj siv lub voltage tsis tshua muaj zog rau lub zog hluav taws xob tsis zoo rau cov khoom siv hluav taws xob tsis zoo rau cov khoom siv hluav taws xob tsis zoo rau cov khoom siv ua haujlwm zoo li no los yog tsis tau ua tiav.

 

Cov lus teb hloov pauv

Lwm qhov chaw uas tso tawm cov kev xav tau lub luag haujlwm loj heev hauv lub tshuab hloov pauv tau sai heev

A low output impedance allows the switcher to respond more quickly to transient changes in the load current. When there is a sudden increase in the load current, a switcher with low output impedance can supply the additional current without a large drop in voltage. This is because the low impedance allows the current to flow more easily from the switcher to the load.

Hloov siab, lub siab ua kom tiav impedance tuaj yeem ua rau cov lus teb qeeb, xws li hauv kev sib txuas lus tam sim no thiab ruaj khov rau hauv cov khoom sib txuas lus lossis cov khoom siv hluav taws xob tsis tu ncua

 

Ua tau zoo

Cov zis Impedance tseem muaj kev cuam tshuam ntawm kev ua tau zoo ntawm lub zog hluav taws xob {{}} Qhov kev ua kom muaj zog ntxiv rau feem ntau ua rau muaj kev ua tau zoo.

Thaum cov zis impedance yog siab, ntau zog yog dissipated nyob rau hauv lub tshuab hloov pauv, thiab (r) yog tam sim no, thiab (r) yog tam sim no, thiab (r) yog tam sim no, thiab (r) tam sim no, thiab (r) tes, cov zis qis impedance txhais tau txhais tau tias tsawg dua sab hauv lub zog poob, yog li ntau ntawm cov hwj chim tawm tau xa mus rau lub thawv {}}}

Piv txwv, nyob rau hauv lub roj teeb - ntaus ntawv siv, kev ua tau zoo heev ntxiv nrog kev txo lub roj teeb lub neej los ntawm kev txo lub hwj chim uas kub.

 

Lub zog tuav lub peev xwm

Cov zis impedance ntawm qhov kev siv hluav taws xob qis kuj cuam tshuam nws lub zog tuav hluav taws xob impedance tuaj yeem ua rau muaj zog ntau dua .

Thaum cov zis impedance yog tsawg, tus hloov hloov tuaj yeem muab cov khoom siv hluav taws xob tam sim no tsis muaj zog -

Ntawm qhov tod tes, lub tshuab hloov pauv nrog cov zis siab tej zaum yuav tsis muaj peev xwm xa cov nyiaj hauv lub zog sab hauv

 

Hom ntawm cov voltage qis thiab tso zis impedance

Muaj ntau hom ntawm cov voltage qis qis hauv peb cov series, thiab txhua tus muaj nws tus yam ntxwv thaum nws los tso zis impedance .

GCK tsawg voltage rho tawm lub zog hloov lub thawv: GCK tsawg voltage rho tawm fais fab hloov lub thawv yog tsim kom muaj zog hluav taws xob {1} Nws muaj cov tshuab tswj kev lag luam rau kev lag luam kev lag luam.

GCS Tsawg Voltage Tshem Cov Hloov Pauv Hloov: GCS tsawg voltage rho tawm hloov chaw tau paub txog nws qhov kev ua tau zoo thiab hloov kho cov khoom siv hluav taws xob zoo} Nws tseem muaj qhov tseem ceeb tshaj plaws {}}

XL21 Tsawg Voltage Txee: XL21 Tsawg Voltage Hluav Taws Xob Hluav Taws Xob yog qhov kev xaiv nrov rau cov khoom siv hluav taws xob me me uas muab cov kev siv hluav taws xob zoo - {5 5}}
