Capacitors yog cov khoom siv feem ntau thiab siv ntau hauv Circuit Court tsim, thiab lawv yog ib qho ntawm cov khoom sib txig. Cov khoom siv nquag yog cov khoom siv yooj yim uas xav tau lub zog (siv hluav taws xob) thiab hu ua cov khoom siv nquag. Cov cuab yeej siv uas tsis tas yuav siv hluav taws xob (hluav taws xob) yog cov khoom siv dhau los. Cov. Cov peev hluav taws xob feem ntau ua lub luag haujlwm tseem ceeb hauv kev kub ceev.
Muaj feem ntau muaj ntau txoj haujlwm thiab kev siv ntawm lub zog siv. Xws li: lub luag hauj lwm hauv kev hla, txiav tawm, lim, lub zog cia; hauv kev ua tiav ntawm oscillation, synchronization thiab lub sijhawm tsis tu ncua ...
Cia' s soj ntsuam nws hauv kev nthuav dav hauv qab no:
1. Kev thaiv DC: Qhov ua haujlwm yog tiv thaiv DC ntawm kev dhau thiab cia AC dhau.
2. Bypass (decoupling): Muab txoj hauv kev qis rau qee qhov sib txuam hauv AC puag ncig.
Bypass capacitor: Bypass capacitor, tseem hu ua decoupling capacitor, yog lub zog cia khoom uas muab lub zog rau lub cuab yeej. Nws siv cov zaus impedance yam ntxwv ntawm lub capacitor (cov yam ntxwv ntawm tus yam ntxwv zoo tagnrho nce nrog qhov zaus, thiab qhov cuam tshuam tsawg dua), Zoo li lub pas dej, nws tuaj yeem ua rau cov zis hluav taws xob cov zis thiab txo qhov hloov voltage hloov mus hloov. Lub bypass capacitor yuav tsum nyob ze li sai tau rau lub hwj huam muab pin thiab av tus pin ntawm lub ntaus khoom. Qhov no yog ib qho impedance yuav tsum tau ua. Tshwj xeeb yuav tsum tau them nyiaj thaum kos cov PCB. Tsuas yog thaum nws nyob ze rau ib qho kev tivthaiv tuaj yeem siv lub ntsuas hluav taws xob lossis lwm cov cim teeb meem yuav raug rho tawm vim yog ntau dhau qhov hluav taws xob. Hauv av muaj peev xwm nce thiab suab nrov, kom tso nws meej meej, yog kom ob peb AC tiv thaiv nyob rau hauv DC lub hwj huam mus rau lub zog hluav taws xob hauv av los ntawm lub zog hluav taws xob, uas ua lub luag haujlwm hauv kev ua kom huv DC lub zog hluav taws xob. Raws li qhia hauv daim duab, C1 yog lub cim kev muaj peev xwm, thiab nws yuav tsum yog ze li sai tau rau IC1 thaum kos duab.
Decoupling capacitor: Lub decoupling capacitor siv qhov cuam tshuam ntawm lub teeb liab tawm ua cov khoom siv lim. Lub decoupling capacitor yog sib piv rau lub roj teeb thiab siv nws lub txim thiab tawm mus rau kom lub teeb liab loj yuav tsis cuam tshuam los ntawm kev hloov tam sim no. Nws lub peev xwm tau txiav txim siab los ntawm qhov ntau zaus ntawm cov teeb liab thiab cov degree ntawm kev tseb rho tawm. Lub decoupling capacitor ua raws li" roj teeb" kom tau raws li qhov hloov ntawm cov tsav hluav taws xob tam sim no thiab zam kev sib txuam sib txuam.
Lub bypass capacitor yog qhov txiav txim siab tiag tiag, tab sis txoj kev bypass capacitor feem ntau hais txog kev siv high-frequency bypass, uas yog, txhawm rau txhim kho lub suab qis qis qis los tiv thaiv cov txheej txheem rau cov hloov suab nrov. High-frequency bypass capacitors feem ntau me me, feem ntau 0.1F, 0.01F, thiab lwm yam raws li cov resonance zaus; thiab lub peev xwm ntawm decoupling capacitors feem ntau loj dua, uas tej zaum yuav yog 10F lossis ntau dua, nyob ntawm seb cov khoom faib rau hauv Circuit Court thiab qhov hloov pauv ntawm tsav tam sim no kom ntseeg tau Daim duab C3 yog qhov ntsuas ntawm ua kom txawv txav
Qhov sib txawv ntawm lawv: Bypass yog coj qhov kev cuam tshuam hauv lub teeb liab tawm tswv yim raws li cov khoom siv lim, thaum decoupling yog coj qhov kev cuam tshuam ntawm cov paib tso tawm raws li cov khoom siv lim kom tiv thaiv kev cuam tshuam cov teeb liab los ntawm rov qab mus rau lub zog hluav taws xob.
3. Kev Ntsuas Khoom: Ua raws li kev sib txuas ntawm ob txoj kev sib txuas, nws tso cai rau AC cov cim kom hla thiab kis tau mus rau hauv Circuit Court tom ntej.
Lub hom phiaj ntawm kev siv cov capacitors los txuas rau cov khoom sib txuas yog xa cov teeb liab ntawm theem ua ntej mus rau theem tom ntej, thiab txiav cov cawv ntawm qhov ncaj qha tam sim no ntawm theem ua ntej rau theem kawg, kom lub Circuit Court debugging yog yooj yim thiab cov kev ua haujlwm ruaj khov.
AC teeb liab amplification yuav tsis hloov pauv yog tias tsis muaj lub zog txuas ntxiv, tab sis cov ntsiab lus ua haujlwm ntawm txhua theem yuav tsum rov ua haujlwm dua. Vim muaj tus yam ntxwv ntawm hauv ntej thiab nram qab theem, qhov debugging ntawm cov ntsiab lus ua haujlwm yog qhov nyuaj heev, thiab nws yuav luag tsis tuaj yeem ua tiav nws nyob hauv ntau theem.
4. Kev lim dej: Qhov no yog qhov tseem ceeb heev rau hauv Circuit Court, thiab lub capacitors tom qab CPU cia li ua qhov no.
Ntawd yog, qhov ntau dua cov zaus f, tus me impedance Z ntawm lub capacitor. Thaum muaj pes tsawg zaus, vim hais tias lub impedance Z ntawm lub zog capacitor C yog tus loj, cov cim tseem ceeb tuaj yeem hla dhau mus; nyob rau ntawm qhov muaj ntau zaus, lub capacitor C yog tsawg heev vim los ntawm impedance Z, uas yog sib npaug rau luv luv-luv-siab-nrov nrov rau GND.
Lub zog cia: khaws lub zog hluav taws xob thiab tso nws thaum tsim nyog.
Xws li lub koob yees duab nyem, cov khoom siv cua sov, thiab lwm yam (Tam sim no, lub zog cia theem ntawm qee lub capacitors ze rau theem ntawm lithium roj teeb, thiab lub zog hluav taws xob khaws cia los ntawm lub zog tau siv rau lub xov tooj ntawm tes rau ib hnub.
Lub zog cia muaj nuj nqi: Feem ntau, cov ntsuas hluav taws xob yuav muaj qhov ua haujlwm ntawm lub zog cia. Rau cov khoom siv hluav taws xob tshwj xeeb txuag lub zog, tus txheej txheem ntawm lub zog capacitor cia khoom yog hluav taws xob ob txheej txheej capacitor thiab Faraday capacitor. Nws daim ntawv tseem ceeb yog supercapacitor lub zog cia. Supercapacitors yog capacitors uas siv lub hauv paus ntawm hluav taws xob ua ob-txheej. Thaum qhov hluav taws xob sab nraud tau thov rau tus supercapacitor Thaum ob daim hlau ntawm tus capacitor yog tib yam li cov ntsuas hluav taws xob, cov hluav taws xob zoo ntawm lub phaj ntim cov nqi zoo, thiab cov phaj tsis zoo khaws cov nqi tsis zoo. Raws li qhov kev txiav txim ntawm cov hluav taws xob hluav taws xob tau tsim los ntawm kev them nyiaj ntawm ob daim phiaj ntawm cov supercapacitor, muaj qhov sib txawv nruab nrab ntawm cov electrolyte thiab cov electrodes. Kev tawm tsam ntawm cov nqi raug tsim rau ntawm lub interface kom sib npaug ntawm cov hluav taws xob sab hauv ntawm qhov hluav taws xob. Qhov no tus nqi them thiab qhov tsis zoo raug teeb tsa ntawm qhov tsis sib thooj nrog qhov sib txawv luv luv ntawm qhov zoo thiab qhov tsis zoo ntawm lub chaw tiv tauj ntawm ob theem sib txawv. Qhov no ntim khoom faib txheej txheej hu ua hluav taws xob ob txheej, yog li lub capacitance loj heev.
