Kev txhawb siab rau Cov Lus Qhia no yog qhov ntev dua los tsim, uas taug qab qhov kev nce qib los ntawm Texas Instruments Robotics System Learning Kit Lab Lab. Thiab qhov kev txhawb siab rau chav kawm ntawd yog tsim (rov tsim dua) kom zoo dua, muaj zog dua neeg hlau. Kuj tseem muaj txiaj ntsig zoo yog "Ntu 9: Kev siv hluav taws xob, Lub zog, thiab lub zog cia hauv lub Capacitor, DC Engineering Circuit Analysis", muaj nyob ntawm MathTutorDvd.com.

Muaj ntau qhov teeb meem uas ib tus yuav tsum tau txhawj xeeb txog thaum tsim lub neeg hlau loj, uas ib tus tuaj yeem feem ntau tsis quav ntsej thaum tsim lub me me lossis cov khoom ua si neeg hlau.

Kev paub ntau dua lossis paub txog capacitors tuaj yeem pab koj ntawm koj txoj haujlwm tom ntej.

Kauj Ruam 1: Qhov Chaw thiab Khoom Siv

Yog tias koj xav ua si ib puag ncig nrog, tshawb xyuas, thiab kos koj tus kheej cov lus xaus, ntawm no yog qee qhov thiab cov cuab yeej siv uas yuav pab tau.

• sib txawv tus nqi resistors
• sib txawv tus nqi capacitors
• jumper cov xov hlau
• laub khawm hloov
• ib daim ntawv qhia zaub mov
• ib qho oscilloscope
• ib voltmetter
• muaj nuj nqi/teeb liab generator

Hauv kuv qhov xwm txheej, kuv tsis muaj lub tshuab hluav taws xob teeb tsa, yog li kuv yuav tsum siv lub micro-controller (MSP432 los ntawm Texas Instruments). Koj tuaj yeem tau txais qee qhov taw qhia ntawm kev ua koj tus kheej los ntawm lwm qhov Qhia Qhia.

(Yog tias koj tsuas xav kom lub rooj tswj hwm micro ua koj tus kheej (Kuv tab tom sau cov lus qhia uas yuav pab tau), MSP432 txoj kev txhim kho pawg thawj coj nws tus kheej tsis kim li ntawm $ 27 USD. Koj tuaj yeem tshawb xyuas nrog Amazon, Digikey, Newark, Element14, lossis Mouser.)

Kauj Ruam 2: Cia Peb Saib Cov Capacitors

Cia peb xav txog lub roj teeb, lub laub-khawm hloov (Pb), tus tiv thaiv (R), thiab lub tshuab hluav taws xob tag nrho hauv koob. Hauv lub voj kaw.

Thaum lub sij hawm xoom t (0), nrog Pb qhib, peb yuav ntsuas tsis muaj qhov hluav taws xob hla ib qho resistor lossis lub capacitor.

Vim li cas? Teb qhov no rau tus tiv thaiv tau yooj yim - tsuas yog tuaj yeem ntsuas qhov ntsuas hluav taws xob thaum muaj qhov tam sim no ntws los ntawm tus tiv thaiv. Hla tus tiv thaiv, yog tias muaj qhov sib txawv hauv qhov muaj peev xwm, uas ua rau muaj qhov tam sim no.

Tab sis txij li qhov hloov pauv tau qhib, yuav tsis muaj qhov tam sim no. Yog li, tsis muaj hluav taws xob (Vr) hla R.

Yuav ua li cas txog hla tus capacitor. Zoo.. dua, tsis muaj tam sim no hauv Circuit Court tam sim no.

Yog tias lub tshuab hluav taws xob raug tshem tawm tag nrho, qhov ntawd txhais tau tias tsis muaj peev xwm sib txawv tuaj yeem ntsuas tau hla nws cov dav hlau.

Yog tias peb thawb (kaw) Pb ntawm t (a), tom qab ntawd yam tau nthuav. Raws li peb tau qhia hauv ib qho ntawm cov vis dis aus, lub capacitor pib tawm thaum tso tawm. Tib theem voltage ntawm txhua lub davhlau ya nyob twg. Xav tias nws yog xaim luv.

Txawm hais tias tsis muaj lub tshuab hluav taws xob tiag tiag ntws los ntawm lub tshuab hluav taws xob sab hauv, muaj tus nqi zoo uas pib tsim ntawm ib lub davhlau ya nyob twg, thiab them tsis zoo ntawm lwm lub davhlau ya nyob twg. Tom qab ntawd nws tshwm (sab nrauv) zoo li yog tias muaj tam sim no.

Ua tias lub tshuab hluav taws xob nyob hauv nws lub xeev tso tawm ntau tshaj, tam sim ntawd yog thaum nws muaj peev xwm tshaj plaws los lees txais tus nqi. Vim li cas? Vim tias raws li nws tau them, qhov ntawd txhais tau tias muaj peev xwm ntsuas tau thoob plaws nws lub davhlau ya nyob twg, thiab qhov ntawd txhais tau tias nws nyob ze rau qhov muaj nuj nqis rau lub roj teeb thov. Nrog qhov sib txawv tsawg dua ntawm kev thov (roj teeb) thiab nws nce tus nqi (qhov nce siab), tsis muaj kev txhawb zog kom khaws cov nqi sib npaug ntawm qhov qub.

Tus nqi tsub nqi qis dua raws sijhawm mus. Peb pom qhov ntawd hauv ob qho yeeb yaj kiab, thiab L. T. Spice simulation.

Txij li thaum nws yog qhov pib uas lub capacitor xav lees txais qhov them nyiaj ntau tshaj plaws, nws ua haujlwm zoo li luv luv ib ntus mus rau qhov seem ntawm lub Circuit Court.

Qhov ntawd txhais tau tias peb yuav tau txais qhov tam sim no dhau los ntawm Circuit Court thaum pib.

Peb pom qhov no hauv daim duab uas qhia txog kev sim sim LTT.

Raws li tus nqi hluav taws xob, thiab nws tab tom tsim hluav taws xob hla nws cov dav hlau mus rau qhov siv hluav taws xob, qhov kev txhawb nqa lossis kev muaj peev xwm them tau raug txo. Xav txog nws - qhov ntau ntawm qhov sib txawv ntawm qhov hluav taws xob hla qee yam, qhov muaj peev xwm ntau ntawm kev ntws tam sim no. Loj loj = ua tau tam sim no loj. Qhov me me = ua tau me me tam sim no. (Feem ntau).

Yog li ntawd raws li lub tshuab hluav taws xob nce mus txog qib theem ntawm lub roj teeb thov, nws zoo li qhib lossis tawg hauv Circuit Court.

Yog li, lub capacitor pib tawm luv luv, thiab xaus li qhib. (Ua qhov yooj yim heev).

Yog li, dua, tam sim no max thaum pib, yam tsawg kawg tam sim no thaum kawg.

Ib zaug ntxiv, yog tias koj sim ntsuas qhov hluav taws xob hla luv luv, koj yuav tsis pom ib qho.

Yog li, hauv lub capacitor, tam sim no yog nws qhov loj tshaj thaum qhov hluav taws xob (hla lub capacitor) yog nyob rau xoom, thiab tam sim no yog qhov tsawg kawg thaum qhov hluav taws xob (hla lub capacitor) yog qhov loj tshaj.

Ib Ntus Cia Thiab Muab Lub Zog

Tab sis muaj ntau ntxiv, thiab nws yog ntu no uas tuaj yeem pab tau hauv peb cov neeg hlau txuas.

Cia peb hais tias lub capacitor raug them. Nws nyob ntawm qhov siv roj teeb qhov hluav taws xob. Yog tias yog vim li cas qee qhov kev siv hluav taws xob tau poob qis ("sag"), tej zaum vim qee qhov xav tau tam sim no hauv kev siv hluav taws xob, hauv qhov xwm txheej ntawd, tam sim no yuav tshwm sim ntws tawm ntawm lub capacitor.

Yog li, cia peb hais tias cov tswv yim siv hluav taws xob tsis yog qib pob zeb-khov kho uas peb xav tau. Lub tshuab hluav taws xob tuaj yeem pab ua kom cov dej ntws tawm (luv).

Kauj Ruam 3: Ib Daim Ntawv Thov Cov Capacitors - Lim Lub Suab nrov

Lub tshuab hluav taws xob tuaj yeem pab peb li cas? Peb tuaj yeem thov qhov uas peb tau pom txog lub capacitor li cas?

Ua ntej, cia ua qauv qee yam uas tshwm sim hauv lub neej tiag tiag: lub tsheb ciav hlau muaj suab nrov hauv peb cov neeg hlau lub voj voog.

Peb siv L. T. Cov txuj lom, peb tuaj yeem tsim lub voj voog uas yuav pab peb txheeb xyuas cov suab nrov uas tuaj yeem tshwm sim hauv peb cov neeg hlau lub voj voog 'txoj kab hluav taws xob. Cov duab qhia pom qhov Circuit Court, thiab Spice tus qauv ntawm qhov ua kom muaj hluav taws xob hluav taws xob ntau theem.

Qhov laj thawj Spice tuaj yeem ua qauv nws yog vim tias kev siv hluav taws xob ("V.5V. Batt") muaj qhov ua haujlwm me ntsis. Tsuas yog rau ncaws, Kuv ua rau nws muaj 1ohm ntawm sab hauv tsis kam. Yog tias koj ua qauv no tab sis tsis ua rau lub hauv paus pov ntawv tawm suab muaj kev tiv thaiv sab hauv, koj yuav tsis pom txoj kev tsheb nqaj hlau poob vim yog lub suab nrov digital, vim tias tom qab ntawd qhov hluav taws xob qhov hluav taws xob yog "qhov zoo tshaj plaws".
