Test Aging Power Supply

Hais lus nqaim, lub nra yog qhov khoom ntawm kev sim cov khoom siv hluav taws xob laus, thiab cov khoom siv hluav taws xob kuj tuaj yeem hais tias yog cov hloov kho tau.

 

Kev sim thiab kev laus ntawm qee yam khoom siv hluav taws xob tsis zoo, xws li lub teeb lub teeb, kev thauj khoom tag nrho, thiab kev thauj khoom hnyav, tshwj xeeb tshaj yog thaum cov khoom siv hluav taws xob yuav tsum hloov pauv qhov yuav tsum tau ua.

 

Hom kev ua haujlwm ntawm cov khoom siv hluav taws xob muaj xws li hom tsis tu ncua tam sim no, hom tsis tu ncua voltage, hom tsis tu ncua, hom hluav taws xob tas li, thiab lwm yam.

 

Hauv hom tam sim no tsis tu ncua, cov khoom siv hluav taws xob nqus tam sim no ntawm tus nqi teeb tsa hauv ib puag ncig daim ntawv thov, txawm hais tias qhov kev hloov pauv hloov pauv li cas.

 

1. Hom tam sim no tsis tu ncua

Hauv hom tam sim no tsis tu ncua, cov khoom siv hluav taws xob nqus tam sim no ntawm tus nqi teeb tsa hauv ib puag ncig daim ntawv thov, txawm hais tias qhov kev hloov pauv hloov pauv li cas.

2. Kev ua haujlwm tsis tu ncua

Nyob rau hauv lub xeev no, lub load (xws li ib tug ntshiab resistor) absorbs ib tug tam sim no proportional rau lub voltage. Txoj kev no yog tsim rau pib thiab kuaj pom. Txwv qhov tam sim no ntawm lub hwj chim mov voltage thiab tam sim no qhov chaw

Hauv hom kev ua haujlwm tsis tu ncua, cov khoom hluav taws xob hluav taws xob absorbs cov input voltage raws li cov kab hluav taws xob tam sim no.

3. Kev ua haujlwm siab tsis tu ncua

Hauv hom hluav taws xob tas li, cov khoom siv hluav taws xob siv hluav taws xob txaus los kho qhov voltage rau tus nqi tsim. Cov hom hluav taws xob tas li tuaj yeem siv los ntsuas qhov txwv tam sim no ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, qhov kev thauj khoom no tuaj yeem siv los kuaj cov roj teeb chargers raws li nws tuaj yeem simulate qhov polarity voltage ntawm lub roj teeb.

4. Lub zog tsis tu ncua

Nyob rau hauv cov nqe lus ntawm lub zog tas li, feem ntau cov khoom hluav taws xob ua haujlwm los ntawm cov khoom siv hluav taws xob tsis tu ncua. Ua ntej, cia peb coj MCU uas xam cov input voltage ua piv txwv, thiab tom qab ntawd peb tuaj yeem suav cov zis tam sim no raws li tus nqi hluav taws xob.
