Indima nomsebenzi wama-capacitors ku-elekthronikhi yanamuhla
Ama-capacitors awumpi abiliatous emhlabeni we-elekthronikhi, esebenza njengezakhi eziyisisekelo ezenza uhlu oluningi lwemisebenzi ebucayi. Noma ngabe kutholakala kuhlelo lokusebenza lomndeni olulula noma uhlelo olunzima lwezimboni, ama-capacitors ahlanganiswe ekusebenzeni nasekusebenzeni kwemibuthano kagesi. Le ndatshana ingena kwizindima ezihlangene zama-capacitors, ukuhlola izimiso zazo eziphansi, izinhlelo zokusebenza, kanye nomthelela kuma-elekthronikhi anamuhla.
1. Ukuqonda izisekelo zama-capacitors
Emgogodleni wayo, i-capacitor iyinto ebonakalayoIngxenye ye-elekthronikhiLokho kugcina amandla kagesi emkhakheni kagesi. Siqukethe amapuleti amabili aphambukayo ahlukaniswe impahla ye-dielectric, esebenza njenge-insulator. Lapho i-voltage isetshenziswa kuwo wonke amapuleti, inkambu kagesi iqala ngaphesheya kwe-dielectric, okubangela ukunqwabelana kwenkokhiso enhle epuletini elilodwa kanye necala elibi ngakolunye. La mandla agciniwe angakhishwa lapho edingeka, okwenza ama-capacitors abaluleke ngezicelo ezahlukahlukene.
1.1I-Capacitance kanye nabasizi bayo
Amandla we-capacitor ukugcina ukushaja kukalwa nge-capacitance yayo, ebonisiwe eFaraDS (F). I-Capacitance ilingana ngqo nendawo engaphezulu kwamapuleti kanye ne-dielectric njalo yezinto ezisetshenzisiwe, kanye nokulingana ngokungafani nebanga phakathi kwamapuleti. Izinhlobo ezahlukene zama-capacitors zenzelwe amanani ahlukahlukene amakhono okuhambisana nezicelo ezithile, ezisukela kumasendulo e-picofarads (PF) kumasekethe afudumele aphezulu kuya kuma-farads kuma-supercapacitors asetshenziselwa ukugcinwa kwamandla.
2. Imisebenzi ebalulekile yama-capacitors
Ama-capacitor enza imisebenzi eminingana ebalulekile emibuthanweni ye-elekthronikhi, ngalinye lifaka isandla ekusebenzeni okuphelele nokuqina kohlelo.
2.1Ukugcinwa Kwamandla
Enye yezindima eziyinhloko ze-capacitor ukugcina amandla. Ngokungafani namabhethri agcina amandla ngamakhemikhali, ama-capacitors agcina amandla e-electrostiance. Leli khono ukugcina ngokushesha nokukhulula amandla kwenza ama-capacitos elungele izinhlelo zokusebenza ezidinga ukuphuma okusheshayo, njengokukhanya kwekhamera, ama-defibrillators kanye nezinhlelo ze-laser ezihlanganisiwe.
Ama-Supercapacitors, uhlobo lwe-capacitor ephezulu, aphawuleka kakhulu ngamakhono abo okugcina amandla. Bavala igebe phakathi kwama-capacitors ajwayelekile namabhethri, anikela ngobuningi bamandla aphezulu kanye nemijikelezo esheshayo / yokukhipha. Lokhu kubenza baligugu kuzinhlelo zokusebenza ezinjengezinhlelo zokuvuselela kabusha ezimotweni zikagesi kanye nezinto zokusekelayo zamandla.
2.2Isihlungu
Emibuthanweni yokunikeza amandla, ama-capacitors adlala indima ebalulekile ekuhlunga. Zibusheleleze ukuguquguquka kwamandla kagesi ngokuhlunga umsindo ongafuneki ne-ripple kusuka kumasiginali e-AC, kuqinisekisa ukuphuma kwe-DC eqinile. Lo msebenzi ubalulekile ekuhlinzekeni kwamandla kwamadivayisi we-elekthronikhi abucayi, lapho kudingeka khona amandla ashukumisekayo ukuvikela ukungasebenzi kahle noma ukulimala.
Ama-capacitor asetshenziswa futhi ngokubambisana ne-Inductor ukudala izihlungi ezivimba noma zidlule amabanga athile athile. Lezi zihlungi zibalulekile kuzinhlelo zokusebenza ezinjengokusebenza komsindo, imvamisa yeRadio (RF), kanye nokusebenza kwesiginali, lapho zisiza ekuhlukaniseni noma ekuqedeni amaza angafuneki.
2.3Ukuhlangana nokuzithoba
Ama-capacitors asetshenziswa kaningi ekuxhumaneni nasekuhlotsheni kwezicelo. Ekuhlanganeni, ama-capacitors avumela amasiginali e-AC ukuthi adlule esigabeni esisodwa somjikelezo kwelinye ikhehla ngenkathi evimba noma iyiphi ingxenye ye-DC. Lokhu kubalulekile ezinhlelweni ze-Amplifiers nasezinhlelweni zokuxhumana, lapho kubalulekile ukudlulisa amasiginali ngaphandle kokuguqula i-baseline voltage yabo.
Ukuqothuka, ngakolunye uhlangothi, kufaka phakathi ukubeka ama-capacitors eduze kwezikhonkwane zokuhlinzekwa kwamandla ezifunda ezihlanganisiwe (ics) ukuze zilondoloze amandla aqinile ngokuthatha ama-voltage spikes futhi anikeze indawo yokugcina yendawo yendawo. Lokhu kubaluleke kakhulu emibuthanweni yedijithali ephezulu yedijithali lapho ukushintshwa okusheshayo kungadala ukuguquguquka okungazelelwe kumandla kagesi, okuholela emaphutheni noma ngomsindo.
2.4Isikhathi kanye ne-oscillation
Ama-capacitors ayizinto ezibalulekile ekuhambeni kwesikhathi nasezisekelweni ze-oscillation. Lapho kuhlangene nabamelana noma i-inducrosors, ama-capacitors angakha i-RC (i-Resistor-capacitor) noma i-LC (induc-capacitor) ekhiqiza ukubambezeleka kwesikhathi noma ama-oscillations. Lemibuthano iyisisekelo ekwakhiweni kwamawashi, isikhathi kanye nama-oscillator asetshenziswa kukho konke kusuka kumawashi edijithali kuya kumsakazo wokudlulisela umsakazo.
Ukushaja kanye nokukhipha izici zama-capacitors kule mibuthano kunquma izikhathi zokugcina isikhathi, okwenza ukuba zibe zibalulekile kwizicelo ezidinga ukulawula isikhathi okunembile, njengasezinhlelweni ezisuselwa ku-microcontroller noma i-PwM) yokushintshashintsha.
2,5Ukuhanjiswa kwamandla
Kuzinhlelo zokusebenza lapho kudingeka khona ukudluliswa kwamandla okusheshayo, ama-capacitors excel ngenxa yekhono lawo lokukhipha amandla agciniwe ngokushesha. Le mpahla ixhashazwa kumadivayisi afana nama-electromagnetic pulse generator, lapho ama-capacitors akhipha khona amandla abo agciniwe ekuqhumeni okunempilo. Ngokufanayo, kuma-defibrillators, ama-capacitors akhipha ngokushesha ukuletha ukushaqeka kukagesi okudingekayo enhliziyweni yesiguli.
