Hauv DC Circuit Court, lub capacitor yog sib npaug rau qhov qhib kev sib txuas lus. Lub tshuab ntsuas hluav taws xob yog lub hauv paus uas muaj peev xwm khaws cov nqi, thiab tseem yog ib qho ntawm cov khoom siv hluav taws xob feem ntau.
Qhov no yuav tsum pib ntawm tus qauv ntawm tus capacitor. Qhov yooj yim tshaj plaws capacitor yog tsim ntawm cov ncej qaum ntawm ob qho kawg thiab ib qho thaiv hluav taws xob (suav nrog huab cua) hauv nruab nrab. Tom qab ua kom muaj zog, cov phaj raug them, tsim cov hluav taws xob (muaj peev xwm sib txawv), tab sis vim yog cov khoom siv insulating hauv nruab nrab, tag nrho cov capacitor tsis muaj conductive. Txawm li cas los xij, qhov xwm txheej no nyob hauv qhov pom tias qhov hluav taws xob tseem ceeb (tawg voltage) ntawm lub capacitor tsis siab tshaj. Peb paub tias txhua yam khoom siv kuj yog qhov ntxig tau. Thaum qhov voltage thoob plaws cov khoom nce mus rau ib qib, cov tshuaj yeeb yaj kiab tuaj yeem ua tau zoo. Peb hu qhov voltage no qhov hluav taws xob tawg. Capacitors tsis zam. Tom qab lub ntsuas hluav taws xob tawg, nws tsis yog tus insulator lawm. Txawm li cas los xij, hauv tsev kawm theem nrab, cov voltages tsis pom hauv Circuit Court, yog li lawv ua haujlwm qis dua qhov hluav taws xob tawg thiab tuaj yeem raug suav tias yog cov tsis muaj zog.
Txawm li cas los xij, hauv AC circuits, cov kev taw qhia ntawm kev hloov pauv tam sim no yog ib qho haujlwm ntawm lub sijhawm. Cov txheej txheem ntawm kev them nyiaj thiab cov paug tawm muaj lub sijhawm. Lub sijhawm no, daim teb hluav taws xob hloov pauv tau tsim nyob nruab nrab ntawm daim phiaj, thiab daim teb hluav taws xob no kuj tseem yog txoj haujlwm hloov nrog lub sijhawm. Qhov tseeb, tam sim no ntws ntawm capacitors hauv daim ntawv hluav taws xob.
Lub luag hauj lwm ntawm capacitors:
Kev Ntsuas Khoom: Lub ntsuas hluav taws xob siv hauv txoj kab txuas txuas hu ua txuas tus lej ntsuas. Hom hluav taws xob txuas hluav taws xob no tau siv dav hauv cov khoom tiv thaiv-capacitance txuas txuas ntxiv thiab lwm qhov txuas txuas ua ke kom ua lub luag haujlwm ntawm kev thaiv DC thiab AC.
● Lub Lim: Lub tshuab hluav taws xob siv hauv lub lim tawm yog hu ua lim capacitor. Lub tshuab hluav taws xob hauv hluav taws xob no siv rau hauv lub zog hluav taws xob lim thiab ntau lub voj voos. Cov lim capacitor tshem tawm cov teeb liab hauv qee cov kab tawm ntawm cov cim tag nrho.
Kev Txiav Txim Siab: Lub ntsuas hluav taws xob siv hauv hauv qhov hluav taws xob hu ua decoupling tau. Qhov hluav taws xob txuas hluav taws xob no siv nyob rau hauv DC voltage muab Circuit Court ntawm ntau yam suab nrov. Lub decoupling capacitor tshem tawm cov kev phom sij tsawg zaus ntawm kev sib txuas sib txuas ntawm txhua qib ntawm lub suab nrov.
High zaus vibration kev tshem tawm: lub capacitor siv nyob rau hauv lub siab ua kom muaj kev co tshem tawm Circuit Court hu ua qhov siab ua siab vibration kev tshem tawm cov capacitor. Nyob rau hauv cov suab tsis zoo lub tswv yim amplifier, txhawm rau tshem tawm qhov loj qhov nws tus kheej siab dhau qhov uas yuav tshwm sim, qhov hluav taws xob hauv lub xov tooj cua no siv rau kev tshem tawm siab heev howling uas yuav tshwm sim hauv cov amplifier.
On Resonance: Lub capacitor siv nyob rau hauv LC resonant Circuit Court yog hu ua resonant capacitor. Lub tshuab hluav taws xob txuas hluav taws xob no yuav tsum muaj nyob rau hauv ob qho tib si LC parallel thiab cov hluav taws xob txuas ntxiv.
Bypass: lub capacitor siv nyob rau hauv txoj kab kev sib tshooj hu ua kev bypass capacitor. Yog tias koj xav tau tshem tawm qee qhov hluav taws xob uas tsis tshua raug teeb meem los ntawm cov teeb liab hauv Circuit Court, koj tuaj yeem siv txoj kev hla dhau ntawm tus lej ntawm cov hluav taws xob. Raws li kev ua haujlwm zaus ntawm lub teeb liab tshem tawm, muaj tag nrho cov kab hluav taws xob (Txhua AC cov cim) Bypass capacitor Circuit Court thiab high zaus bypass capacitor Circuit Court.
Qhov nruab nrab nruab nrab: Lub tshuab hluav taws xob siv hauv qhov nruab nrab los tiv thaiv hluav taws xob yog hu ua neutralization capacitor. Qhov nruab nrab ntawm nruab nrab qhov nruab nrab ntawm cov xov hluav taws xob no siv nyob rau hauv qhov loj thiab ntau zaus ntawm cov xov tooj cua loj thiab ntau zaus ntawm lub xov tooj cua kom tshem tawm tus kheej kev ntxhov siab.
● Sijhawm Sijhawm: Lub ntsuas hluav taws xob siv hauv lub sijhawm ua ke hu ua lub sijhawm ua ke. Cov sijhawm siv hluav taws xob siv hluav taws xob tau siv rau hauv cov xov xwm uas yuav tsum tau tswj lub sijhawm los ntawm lub txim hluav taws xob thiab kev tso tawm, thiab lub capacitor ua lub luag haujlwm hauv kev tswj qhov loj ntawm lub sijhawm.
Kev sib xyaw ua ke: Lub ntsuas hluav taws xob siv hauv qhov sib xyaw ua ke yog hu ua kev sib xyaw ua ke. Hauv synchronous kev sib cais Circuit Court ntawm tej qhov kev sib tham hauv lub tshav pob, qhov kev sib xyaw hluav taws xob hauv lub xov tooj hluav taws xob no tuaj yeem siv los txhawm rau txhawm rau ntsuas phiaj xwm synchronization ntawm qhov chaw teeb tsa hluav taws xob sib xyaw.
● Kev hloov pauv txawv: Lub tshuab hluav taws xob siv hauv qhov hluav taws xob sib txawv hu ua kev sib txawv ntawm cov hluav taws xob. Txhawm rau kom tau txais lub teeb liab apex nyob rau hauv qhov kev sib tw hauv Circuit Court, hom kev sib txawv ntawm qhov ntsuas hluav taws xob tsis sib xws yog siv los txais lub apex pulse trigger teeb liab los ntawm ntau hom (feem ntau yog cov duab sib dhos pulse).
● Kev Them Nyiaj: Cov ntsuas hluav taws xob uas siv rau hauv lub rooj sib hais raug them nyiaj hu ua kev them nyiaj rov qab. Nyob rau hauv cov ntses bass thaj tsam ntawm qhov lawj, qhov no tsawg zaus them tus xov tooj liab hluav taws xob hluav taws xob tau siv los txhim kho qhov qis-tsawg zaus hauv cov teeb liab playback. Ntxiv rau, muaj qhov them nqi hluav taws xob ntau Circuit Court capacitor Circuit.
● Booststroke: Lub capacitor siv hauv txoj hlua txuas nraub qaum yog hu ua bootstrap capacitor. Feem ntau siv OTL fais fab amplifier tso tawm theem hluav taws xob siv lub pob hluav taws xob no cov hluav taws xob txuas hluav taws xob kom nce me ntsis ib qho zoo ib nrab-ntu kev hloov ntawm lub teeb liab los ntawm kev tawm tswv yim zoo.
Kev faib zaus: Lub ntsuas hluav taws xob hauv qhov zaus faib hluav taws xob hu ua qhov zaus faib hluav taws xob. Hauv kev hais lus zaus faib hluav taws xob Circuit Court ntawm tus hais lus, zaus faib hluav taws xob capacitor Circuit Court yog siv los ua lub siab hais ua haujlwm nyob rau hauv lub siab zaus, thiab cov kab lus nruab nrab zaus ua haujlwm nyob hauv nruab nrab zaus band, tsawg zaus Tus hais lus ua haujlwm hauv qis zaus band.
● Load capacitance: hais txog qhov ua tau zoo sab nraud ntawm qhov nruab nrab uas txiav txim siab qhov load resonance zaus ua ke nrog quartz crystal resonator. Cov kev cai siv dav siv rau cov teeb meem kev thauj khoom muaj peev xwm yog 16pF, 20pF, 30pF, 50pF thiab 100pF. Tus load capacitance tuaj yeem hloov kho kom haum raws li qhov xwm txheej tshwj xeeb, thiab kev ua haujlwm zaus ntawm lub tshuab hluav taws xob tuaj yeem hloov kho mus rau tus nqi me me los ntawm kev kho kom haum.
