Kwisekethe ye-DC, i-capacitor ilingana nokuvula isiphaluka.I-Capacitor luhlobo lwecandelo elinokugcina intlawulo yombane, kwaye ikwayenye yezona zinto zisetyenziswa kakhulu.izixhobo ze-elektroniki.Oku kuqala ngesakhiwo se-capacitor.I-capacitors elula kakhulu iqukethe iiplate ze-polar kuzo zombini iziphelo kunye ne-dielectric ekhuselayo (kubandakanywa nomoya) phakathi.Xa unamandla, iiplate zihlawuliswa, zenza i-voltage (umahluko onokwenzeka), kodwa ngenxa yezinto ezikhuselayo eziphakathi, i-capacitor yonke ayiqhubeki.Nangona kunjalo, le meko iphantsi komqathango wokuba i-voltage ebalulekileyo (i-voltage ye-breakdown) ye-capacitor ayigqithiswanga.Njengoko sisazi, nayiphi na into ikhuselwe ngokwentelekiso.Xa i-voltage kwi-substance inyuka ukuya kumlinganiselo othile, zonke izinto zinokuqhuba umbane, obizwa ngokuba yi-breakdown voltage.IiCapacitors azikho ngaphandle.Emva kokuba ii-capacitors ziphukile, azikho i-insulators.Nangona kunjalo, kwinqanaba lesikolo esiphakathi, i-voltages enjalo ayibonwa kwisekethe, ngoko ke zonke zisebenza ngaphantsi kwe-voltage yokuphazamiseka kwaye zinokuthathwa njenge-insulators.Nangona kunjalo, kwiisekethe ze-AC, isalathiso sotshintsho lwangoku njengomsebenzi wexesha.Inkqubo yokutshaja kunye nokukhupha i-capacitors inexesha.Ngeli xesha, umbane oguqukayo wenziwa phakathi kwee-electrodes, kwaye le ndawo yombane nayo ingumsebenzi wokutshintsha kunye nexesha.Enyanisweni, ngoku idlula phakathi kwee-capacitors ngendlela yombane.
Umsebenzi we-capacitor:
●Ukudityaniswa:I-capacitor esetyenziswe kwisekethe yokudibanisa ibizwa ngokuba yi-coupling capacitor, esetyenziswa ngokubanzi kwi-process-capacitance coupling amplifier kunye nezinye iisekethe zokudibanisa i-capacitive, kwaye idlala indima yokuhlukanisa i-DC kunye nokudlula i-AC.
●Uhluzo:Iicapacitors ezisetyenziswa kwiisekethe zokucoca zibizwa ngokuba zii-filter capacitors, ezisetyenziswa kwisihluzi samandla kunye neesekethe ezahlukeneyo zokucoca.Iicapacitors zesihluzi zisusa imiqondiso ngaphakathi kwebhendi ethile yefrikhwensi ukusuka kumqondiso opheleleyo.
●Uqhawulo-mtshato:Iicapacitors ezisetyenziswa kwiisekethe zokuqhawula zibizwa ngokuba yi-decoupling capacitors, ezisetyenziswa kwiisekethe zobonelelo lombane we-DC we-multistage amplifiers.I-Decoupling capacitors isusa uqhagamshelo oluyingozi olusezantsi-frequency phakathi kweamplifier yenqanaba ngalinye.
●Ukuphelisa ukungcangcazela kwamaza amaninzi:I-capacitor esetyenziswa kwisekethe yokuphelisa i-vibration ephezulu ibizwa ngokuba yi-high frequency vibration elimination capacitor.Kwi-audio negative amplifier yeamplifier, ukuze kupheliswe i-self-excitation ephezulu enokuthi yenzeke, le sekethi ye-capacitor isetyenziselwa ukuphelisa ukukhala okuphezulu okunokuthi kwenzeke kwi-amplifier.
●Izandi:Iicapacitors ezisetyenziswa kwiisekethe ze-LC resonant zibizwa ngokuba yi-resonant capacitors, ezifunekayo kwi-LC parallel kunye neesekethe ze-resonant.
●Ukugqitha:I-capacitor esetyenziswe kwisekethe ye-bypass ibizwa ngokuba yi-bypass capacitor.Ukuba isignali kwibhendi ethile ye-frequency kufuneka isuswe kwisignali kwisiphaluka, i-bypass capacitor circuit ingasetyenziswa.Ngokobuxhakaxhaka bomqondiso osusiweyo, kukho i-domain epheleleyo (yonke imiqondiso ye-AC) i-bypass capacitor circuit kunye ne-high frequency bypass capacitor circuit.
●Ukungathathi hlangothi:Iicapacitors ezisetyenziswe kwiisekethe zokungathathi hlangothi zibizwa ngokuba yi-neutralization capacitors.Kwirediyo yefrikhwensi ephezulu kunye ne-intermediate frequency amplifiers kunye ne-TV high frequency amplifiers, le sekethe ye-neutralization capacitor isetyenziselwa ukuphelisa ukuzihlaziya.
●Ixesha:Iicapacitors ezisetyenziswe kwiisekethe zexesha zibizwa ngokuba yi-timing capacitors.Ixesha le-capacitor circuit lisetyenziswe kwisekethe efuna ukulawula ixesha ngokushaja kunye nokukhupha i-capacitors, kwaye i-capacitors idlala indima yokulawula ixesha elingaguqukiyo.
●Udibaniso:Iicapacitors ezisetyenziswe kwiisekethe zokudibanisa zibizwa ngokuba yi-integration capacitors.Kwisekethe yolwahlulo olulungelelanisiweyo lokuskena indawo yombane enokwenzeka, isiginali ye-synchronous yentsimi inokutsalwa kwisiginali yekhompawundi yentsimi ngokusebenzisa le sekethi yecapacitor edibeneyo.
●Umahluko:Iicapacitors ezisetyenziswe kwiisekethe ezihlukeneyo zibizwa ngokuba yi-different capacitors.Ukuze ufumane i-spike trigger signal kwi-flip-flop circuit, i-differential capacitor circuit isetyenziselwa ukufumana i-spike pulse trigger signal evela kwiimpawu ezahlukeneyo (ikakhulukazi i-pulse rectangular).
●Imbuyekezo:I-capacitor esetyenziswe kwisiphaluka sembuyekezo ibizwa ngokuba yi-compensation capacitor.Kwisekethe yembuyekezo ye-bass yomnini wekhadi, le ngqungquthela ye-capacitor ye-capacitor ye-low-frequency compensation isetyenziselwa ukuphucula isignali ye-low-frequency kwisignali yokudlala.Ukongeza, kukho i-high frequency compensation capacitor circuit.
●I-Bootstrap:I-capacitor esetyenziswe kwisekethe ye-bootstrap ibizwa ngokuba yi-bootstrap capacitor, esetyenziswa ngokuqhelekileyo kwisiphaluka sesigaba sokuphuma se-OTL yokwandisa amandla okwandisa i-half-cycle amplitude yesiginali ngempendulo efanelekileyo.
●Ukwahlulahlula rhoqo:I-capacitor kwi-frequency division circuit ibizwa ngokuba yi-frequency division capacitor.Kwisekethe yolwahlulo lwamaza esandisi-zwi kwibhokisi yesandi, i-frequency division capacitor circuit isetyenziselwa ukwenza i-high-frequency isebenze isandisi-zwi kwibhendi ye-high-frequency, i-medium-frequency-frequency-loudspeaker isebenze kwi-medium-frequency band kunye ne-low-frequency. umsebenzi wesandisi-lizwi kwibhendi yefrikhwensi ephantsi.
●Umthamo wokulayisha:ibhekisela kwi-capacitance esebenzayo yangaphandle emisela i-resonant frequency yomthwalo kunye ne-quartz crystal resonator.Amaxabiso aqhelekileyo aqhelekileyo omthwalo we-capacitors yi-16pF, 20pF, 30pF, 50pF, kunye ne-100pF.I-capacitance yomthwalo inokulungelelaniswa ngokwemeko ethile, kwaye i-frequency yokusebenza ye-resonator inokulungiswa kwixabiso legama ngokuyilungisa.
Okwangoku, imboni yefilimu ye-capacitor ingena kwixesha lophuhliso oluzinzile ukusuka kwi-a
ixesha lokukhula ngokukhawuleza, kunye namandla entsha kunye endala kinetic kushishino kwi
inqanaba lotshintsho.
