Lub programmable DC fais fab mov ua haujlwm li cas?
Nrog rau kev txhim kho txuas ntxiv ntawm ntau yam khoom siv hluav taws xob, lawv kuj muaj cov kev xav tau siab dua rau DC fais fab mov. Piv nrog rau cov khoom siv hluav taws xob, tsis muaj txoj hauv kev los ua kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob nrog ib qho DC fais fab mov, yog li cov khoom siv hluav taws xob sib txawv DC xav tau. Cov khoom siv hluav taws xob fais fab. Ib qho programmable DC fais fab mov yog ib qho xws li. Hauv kev sim ntau lawm, qhov ntau qhov hluav taws xob tawm ntawm qhov programmable DC fais fab mov yog tsim rau kev sim thiab tshuaj xyuas cov yam ntxwv ntawm cov khoom, circuits, modules thiab cov tshuab ua tiav. Hnub no, Antai Test yuav qhia txog lub hauv paus ntsiab lus ua haujlwm ntawm programmable DC fais fab mov.
Programmable DC Power Supply Taw Qhia
Cov tsis-electrostatic quab yuam nyob rau hauv lub programmable DC fais fab mov cov ntsiab lus ntawm qhov tsis zoo mus rau qhov zoo. Thaum lub programmable DC fais fab mov txuas nrog rau sab nraud Circuit Court, vim yog lub zog ntawm lub zog hluav taws xob, tam sim no los ntawm tus ncej zoo mus rau tus ncej tsis zoo yuav raug tsim tawm sab nraud lub zog hluav taws xob (sab nraud Circuit Court). Nyob rau hauv lub hwj chim mov (sab hauv Circuit Court), qhov kev txiav txim ntawm tsis-electrostatic quab yuam ua rau tam sim no ntws los ntawm tus ncej tsis zoo mus rau tus ncej zoo, thiaj li hais tias tus nqi tsim ib lub voj kaw.
Ib qho tseem ceeb ntawm lub programmable DC fais fab mov yog nws lub zog hluav taws xob, uas yog sib npaug rau kev ua haujlwm los ntawm lub zog tsis muaj hluav taws xob thaum lub zog ntawm qhov zoo txav los ntawm qhov tsis zoo mus rau qhov zoo los ntawm sab hauv ntawm lub zog hluav taws xob. Thaum lub zog muab hluav taws xob muab lub zog rau hauv Circuit Court, lub zog muab P yog sib npaug rau cov khoom ntawm lub zog hluav taws xob E ntawm lub zog hluav taws xob thiab tam sim no I, P=EI. Lwm tus yam ntxwv muaj nuj nqis ntawm cov khoom siv hluav taws xob yog nws qhov kev tiv thaiv sab hauv (kev ua haujlwm sab hauv luv luv) R0. Thaum qhov tam sim no los ntawm lub hwj chim mov yog kuv, lub thermal hwj chim poob nyob rau hauv lub hwj chim mov (uas yog, lub Joule tshav kub generated ib lub sij hawm unit) yog sib npaug rau R0I.
Thaum qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob tsis txuas nrog, cov khoom siv hluav taws xob yog nyob rau hauv lub xeev qhib, thiab qhov sib txawv ntawm ob lub electrodes ntawm lub hwj chim mov yog sib npaug rau lub zog hluav taws xob ntawm lub zog hluav taws xob. Nyob rau hauv lub xeev qhib Circuit Court, tsis muaj kev sib hloov pauv ntawm cov hluav taws xob tsis muaj hluav taws xob thiab hluav taws xob hluav taws xob. Thaum lub load resistor txuas nrog rau ob tug ncej ntawm lub hwj huam mov los tsim ib lub voj kaw, cov tam sim no ntws los ntawm lub hwj chim mov ntws los ntawm tus ncej tsis zoo mus rau tus ncej zoo. Lub sijhawm no, lub zog EI muab los ntawm cov khoom siv hluav taws xob sib npaug sib npaug ntawm lub zog UI (U xa mus rau sab nraud Circuit Court (U yog qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob) thiab thermal zog R 0Kuv poob rau hauv qhov kev tiv thaiv sab hauv, EI=UIR0I. Yog li ntawd, thaum lub hwj chim mov Thaum muab lub hwj chim rau lub load kuj, qhov sib txawv ntawm ob tug ncej ntawm lub hwj chim khoom yog U=ER0I.
Thaum lwm lub zog hluav taws xob nrog lub zog hluav taws xob loj dua txuas nrog lub zog hluav taws xob nrog lub zog hluav taws xob me me, tus ncej zoo txuas nrog tus ncej zoo, thiab tus ncej tsis zoo txuas nrog tus ncej tsis zoo (piv txwv li, lub tshuab hluav taws xob DC yog siv. kom them lub roj teeb pob), thiab tam sim no ntws los ntawm tus ncej zoo mus rau tus ncej tsis zoo nyob rau hauv lub hwj chim mov nrog ib tug me me electromotive quab yuam. Lub sijhawm no, cov khoom siv hluav taws xob sab nraud UI sib npaug rau cov lej ntawm lub zog EI khaws cia hauv lub zog hluav taws xob ib lub sijhawm thiab lub zog hluav taws xob R{{0}}Kuv poob rau hauv qhov tsis kam, thiab UI =EIR0I. Yog li ntawd, thaum lub zog sab nraud nkag mus rau lub zog hluav taws xob, qhov hluav taws xob sab nraud siv nruab nrab ntawm ob tus ncej ntawm lub zog hluav taws xob yuav tsum yog U=ER0I.
Thaum qhov kev tiv thaiv sab hauv ntawm lub programmable DC fais fab mov tuaj yeem tsis quav ntsej, nws tuaj yeem txiav txim siab tias lub zog hluav taws xob ntawm lub zog hluav taws xob yog kwv yees li sib npaug ntawm qhov sib txawv lossis qhov hluav taws xob ntawm ob tus ncej ntawm lub zog hluav taws xob.
Txhawm rau kom tau txais DC voltages siab dua, cov khoom siv hluav taws xob DC programmable feem ntau yog siv hauv series. Lub sijhawm no, tag nrho cov hluav taws xob hluav taws xob yog qhov sib npaug ntawm tag nrho cov khoom siv hluav taws xob hluav taws xob, thiab tag nrho cov kev tiv thaiv sab hauv kuj yog qhov suav ntawm tag nrho cov khoom siv hluav taws xob sab hauv. Vim muaj qhov ua kom muaj zog sab hauv, nws tsuas yog siv tau rau hauv circuits uas tsis tshua muaj zog tam sim no. Txhawm rau kom tau txais kev siv tam sim no ntau dua, programmable DC fais fab khoom siv nrog sib npaug electromotive rog tuaj yeem siv ua ke. Lub sijhawm no, tag nrho cov hluav taws xob hluav taws xob yog lub zog hluav taws xob ntawm ib lub zog hluav taws xob, thiab tag nrho cov khoom siv hluav taws xob sab hauv yog qhov sib txuas sib txuas tus nqi ntawm cov khoom siv hluav taws xob sab hauv.
