Yuav ua li cas siv DC fais fab tuag, thiab cov ntsuas uas xav tau kev saib xyuas?
DC cov khoom siv hluav taws xob yog qhov ntsuas uas ua rau lub zog ntshiab thiab ruaj khov. Ntxiv nrog rau tus naj npawb ntawm cov channel, tag nrho cov hwj chim, kev tawm tsam ntawm txhua qhov ntsuas tau ua hauv qab no txhawm rau txhawm rau siv DC fais fab tuag:
Thauj cov nqi kho mob sib tham
Nyob rau hauv contrant voltage tso zis lub xeev, thaum lub load (tawm tam sim no) hloov, cov zis voltage e kuj hloov pauv, txhais tau tias yog △ out. Txoj kev ntsuas hluav taws xob tas li ntsuas qhov ntsuas muaj feem cuam tshuam txog kev sib raug zoo sib xws ntawm △ out thiab E.
Nyob rau hauv tas sij hawm tam sim no lub xeev, thaum lub thauj khoom (cov zis voltage) hloov, cov zis tam sim no kuv yuav hloov pauv, txhais tau tias yog △ iout. Tus tas sim tam sim no load tus nqi kev tswj hwm qhia txog kev sib raug zoo sib xws ntawm eet thiab I.
Tus nqi tswj hwm hluav taws xob tiv thaiv
Nyob rau hauv tas sij hawm voltage tawm (tag nrho cov kev hnav ris tsho) lub xeev, thaum lub tswv yim tawm hluav taws xob e hloov pauv (± 10%), cov zis hluav taws xob e yuav hloov pauv, txhais tau tias yog △ out. Txoj cai tswj hwm tas li linear tus nqi kev tswj hwm kev sib raug zoo sib xws ntawm Δ eout thiab E.
Nyob rau hauv tas sij hawm tam sim no lub xeev (tag nrho cov kev hnav ris tsho), thaum lub tswv yim hluav taws xob e kev hloov pauv (± 10%), cov zis tam sim no kuv yuav hloov pauv, tsis hloov pauv li △ iout. Qhov kev cai lij choj tam sim no muaj feem cuam tshuam txog kev sib raug zoo sib npaug ntawm △ i. Feem ntau yog * * * * * Tus nqi tam sim no + OFFSET.
ruaj khov
Nyob rau hauv qhov chaw sov tas li, qhov tso zis hluav taws xob thiab hloov pauv tsis tau li ntawm 8 teev. Feem ntau * * * *% x tso zis voltage tus nqi / tus nqi tam sim no + bias sawv cev
coefficient
Thaum qhov ntsuas kub hloov los ntawm 1 degree, cov zis hluav taws xob lossis hloov tam sim no. Feem ntau * * * *% x tso zis voltage muaj nuj nqis / tam sim no
Tus nqi + kev tsis ncaj ncees sawv cev.
Ripple thiab nrov nrov
Ripple yog tus AC tivthaiv ntawm DC voltage. Feem ntau, DC voltage tau tau los ntawm kev ua kom zoo thiab lim ac voltage, thiab vim tsis tiav lim, seem ac Cheebtsam yuav nyob twj ywm. Txawm hais tias powered los ntawm cov roj teeb, ripples tseem yuav tsim vim kev thauj khoom hloov pauv. Feem ntau yog sawv cev los ntawm VPP thiab RMS cov txiaj ntsig ntawm ripple thiab nrov.
kev ua yog
Programming qhov tseeb: Qhov taw qhia ntawm qhov yuam kev ntawm cov teeb tsa tus nqi thiab cov tso zis tseeb.
Nyeem rov qab qhov tseeb: Qhov ntsuas yuam kev ntawm cov zis tiag tiag tus nqi thiab cov khoom pom ntawm tus nqi nyeem rov qab.
Cov lus teb hloov pauv
Thaum lub thauj khoom tam sim no hloov tam sim no, cov zis hluav taws xob hloov pauv thiab lub sijhawm ua tiav. Lub sijhawm nws yuav siv rau cov zis hluav taws xob kom rov zoo li ntawm 15mv thaum cov zis tam sim no hloov mus rau ib nrab load los yog ntawm ib nrab thauj mus rau tag nrho cov kev thauj khoom.
