1. Muaj ntau txoj hauv kev khaws cia hluav taws xob
Hauv cov ntsiab lus nrov tshaj plaws, capacitors khaws cov hluav taws xob hluav taws xob. Cov roj teeb khaws cov tshuaj siv hluav taws xob hloov los ntawm hluav taws xob hluav taws xob. Lub qub tsuas yog hloov lub cev, qhov tom kawg yog kev hloov tshuaj.
2. Qhov ceev thiab zaus ntawm kev them nqi thiab tawm yog txawv.
Vim hais tias lub capacitor ncaj qha khw muag khoom nqi. Yog li ntawd, kev them nqi thiab kev tso tawm ceev yog ceev heev. Feem ntau, nws tsuas yog siv ob peb feeb lossis feeb kom them tag nrho lub peev xwm loj; thaum them lub roj teeb feem ntau yuav siv sij hawm ob peb teev thiab cuam tshuam los ntawm qhov kub thiab txias. Qhov no kuj yog txiav txim los ntawm qhov xwm ntawm cov tshuaj tiv thaiv. Capacitors yuav tsum tau them thiab tso tawm tsawg kawg yog kaum tawm txhiab mus rau pua pua lab lub sijhawm, thaum cov roj teeb feem ntau tsuas muaj ntau pua lossis ntau txhiab zaus.
3. Kev siv sib txawv
Capacitors tuaj yeem siv rau kev sib txuas, decoupling, filtering, theem hloov, resonance thiab ua lub zog cia Cheebtsam rau instantaneous loj tawm tam sim no. Lub roj teeb tsuas yog siv los ua lub zog hluav taws xob xwb, tab sis nws kuj tuaj yeem ua lub luag haujlwm hauv kev ruaj ntseg hluav taws xob thiab lim dej hauv qee qhov xwm txheej.
4. Cov yam ntxwv voltage txawv
Txhua lub roj teeb muaj qhov nominal voltage. Cov roj teeb sib txawv yog txiav txim siab los ntawm cov khoom siv electrode sib txawv. Xws li cov roj teeb lead-acid 2V, npib tsib xee hlau hydride 1.2V, lithium roj teeb 3.7V, thiab lwm yam. Lub roj teeb txuas ntxiv them thiab tawm ntawm qhov hluav taws xob no ntev tshaj plaws. Cov capacitors tsis muaj qhov yuav tsum tau muaj rau qhov voltage, thiab tuaj yeem nyob ntawm 0 mus rau ib qho hluav taws xob (qhov kev tiv thaiv hluav taws xob muaj nyob rau ntawm lub capacitor yog qhov ntsuas kom ntseeg tau tias kev siv lub capacitor muaj kev nyab xeeb, thiab tsis muaj dab tsi cuam tshuam nrog cov yam ntxwv ntawm lub capacitor).
Thaum lub sij hawm tus txheej txheem tso tawm, lub roj teeb yuav tenaciously "tseem" nyob ze ntawm lub nominal voltage nrog load, kom txog thaum nws thaum kawg tuav tsis tau thiab pib poob. Lub capacitor tsis muaj lub luag haujlwm no los "kho". Qhov hluav taws xob txuas ntxiv yuav poob nrog qhov ntws los ntawm qhov pib tawm, yog li thaum lub zog txaus txaus, qhov hluav taws xob tau poob mus rau qib "txaus ntshai".
5. Cov nqi them thiab cov kab tawm tawm txawv txawv
Tus nqi thiab tawm nkhaus ntawm lub capacitor yog nruj heev, thiab qhov tseem ceeb ntawm cov nqi thiab cov txheej txheem tawm tuaj yeem ua tiav hauv ib qho tam sim, yog li nws tsim nyog rau cov khoom siv hluav taws xob siab, siab zog, ceev them thiab tawm. Qhov nkhaus nkhaus no muaj txiaj ntsig zoo rau cov txheej txheem them nyiaj, cia nws ua kom tiav sai. Tab sis nws dhau los ua qhov tsis zoo thaum tso tawm. Kev poob qis hauv qhov hluav taws xob sai ua rau nws nyuaj rau cov capacitors los hloov cov roj teeb ncaj qha hauv cov khoom siv hluav taws xob. Yog tias koj xav nkag mus rau hauv lub tshav pob ntawm lub zog, koj tuaj yeem daws tau ob txoj hauv kev. Ib qho yog siv nws ua ke nrog lub roj teeb kom kawm los ntawm ib leeg lub zog thiab qhov tsis muaj zog. Lwm qhov yog los koom tes nrog DC-DC module los tsim kom muaj qhov tsis txaus ntawm lub capacitor tawm nkhaus, kom lub capacitor tuaj yeem muaj qhov hluav taws xob tso tawm kom ruaj khov li sai tau.
6. Muaj peev xwm siv cov capacitors los hloov cov roj teeb
Capacitance C = q.ⅴ(qhov twg C yog lub capacitance, q yog tus nqi hluav taws xob them los ntawm lub capacitor, thiab v yog qhov sib txawv ntawm daim hlau). Qhov no txhais tau hais tias thaum lub capacitance raug txiav txim, q / v yog qhov tsis tu ncua. Yog tias koj yuav tsum muab piv nrog lub roj teeb, koj tuaj yeem nkag siab ib ntus ntawm q ntawm no yog lub peev xwm ntawm lub roj teeb.
Yuav kom ua kom pom tseeb dua, peb yuav tsis siv lub thoob ua ib qho piv txwv. Lub capacitance C zoo li txoj kab uas hla ntawm lub thoob, thiab cov dej yog qhov hluav taws xob ntau q. Tau kawg, qhov loj ntawm txoj kab uas hla, dej ntau nws tuaj yeem tuav tau. Tab sis nws tuav tau npaum li cas? Nws kuj nyob ntawm qhov siab ntawm lub thoob. Qhov siab no yog qhov voltage siv rau lub capacitor. Yog li ntawd, nws tseem tuaj yeem hais tias yog tias tsis muaj qhov txwv siab tshaj plaws, lub tshuab hluav taws xob farad tuaj yeem khaws tag nrho lub ntiaj teb lub zog hluav taws xob!
