Lub series kev twb kev txuas ntawm capacitors li ib qho kev xaiv xaiv capacitance

Condenser - ib tug heev xov tooj cua Cheebtsam, uas yog pom nyob rau hauv tag nrho cov tswv yim. Nws muaj ob conductors sib cais los ntawm ib tug dielectric (nyob ntawm seb lub hom capacitors siv nws cov ntau hom), i.e. lub cev no Circuit Court, tab sis tus nqi yuav tsim nyob rau hauv lub dielectric. Lub ntsiab yam ntxwv ntawm tej capacitor yog lub peev xwm los cia xwb - capacitance thiab nyob voltage ntawm qhov hluav taws xob xwb. Lub electrolytic capacitors muaj polarities, thiab yog yus muaj los ntawm ib tug loj muaj peev xwm thiab ib tug ntau yam ntawm voltages, daim ntawv mas zoo kev nyuaj siab, tab sis muaj ib tug me me muaj peev xwm. Muaj kuj pab kiag li lawm uas ua muaj peev xwm, tab sis txhua yam - nws daim ntawv thov.

Feem ntau hams yuav ntsib nrog qhov teeb meem ntawm kev xaiv ntawm capacitors ntawm capacitance los yog voltage. Cov tub txawg paub: nyob rau hauv lub qhaj ntawv ntawm txoj cai, koj muaj peev xwm sau ib ke ntawm ob peb seev, xws li lub roj teeb. Nyob rau hauv lub neej coj roj teeb yog tso cai, thaum uas tig mus thiab series kev twb kev txuas ntawm capacitors.

Txuas pab kiag li lawm nyob rau hauv parallel, nws yog tau mus cuag ib qho kev nce nyob rau hauv lub peev xwm. General nyob rau hauv no roj teeb yuav tsum tau sib npaug zos rau cov sum ntawm tag nrho cov capacitances (Ceq. = C1 + C2 + ...), cov voltage rau txhua lub caij yuav tau sib npaug. Qhov no txhais tau hais tias tsawg kawg nkaus voltage ntawm lub capacitor, nyob rau hauv lub chaw tub rog ntawm lub hos, yog lub siab tshaj plaws rau tag nrho roj teeb.

Series kev twb kev txuas ntawm capacitors siv nyob rau hauv ib rooj plaub uas nws yog tsim nyog los ua rau kom cov voltage uas yuav withstand cov khoom siv los yog txo lawv lub peev xwm. Nyob rau hauv no embodiment, ntsiab yog kev cob cog rua raws li nram no: pib nrog ib kawg ntawm lub lwm yam, uas yog lub "plus" rau ib tug "rho tawm" lwm yam. Peev Xwm sib npaug capacitor nyob rau hauv cov ntaub ntawv no yog xam los ntawm cov nram qab no mis :. 1 / Ceq = 1 / C1 + 1 / C2 + ... From los ntawm no, hais tias ob capacitors Ceq = C1 * C2 / (C1 + C2), thiab yog li ntawd, lub roj teeb peev xwm yuav tsawg tshaj li qhov tsawg kawg nkaus peev xwm, siv nyob rau hauv nws.

Txuas. Los mus laij lub capacitance ntawm xws li ib tug ntaus ntawv nyob rau hauv uas lub applied thaum uas tig mus thiab series kev twb kev txuas ntawm capacitors, Circuit Court tawg mus rau hauv khej, ces successively xam muaj peev xwm ntawm txhua tus ntawm lawv. Yog li, lub xam capacitance C12 = C1 + C2, ces Ceq = C12 * C3 / (C3 + C12).

Los ntawm lub tsev lag luam ntawm capacitor nyiaj nrog txawv configurations thiab npaj
kev twb kev txuas, koj yuav tsum khaws tej peev xwm rau tej xav voltage. Series kev twb kev txuas ntawm capacitors, raws li zoo raws li tag nrho, siv nyob rau hauv ntau npaj txhij-ua amateur circuits. Nyob rau hauv cov ntaub ntawv no nws yuav tsum coj mus rau hauv tus account lub fact tias txhua capacitor muaj ib tug heev ib qho tseem ceeb ib tug neeg parameter - lub to tam sim no, nws yuav Unbalance voltage nyob rau hauv thaum uas tig mus kev twb kev txuas thiab capacitance nyob rau hauv series. Nws yog ib qho tseem ceeb heev los xaiv tus yuav tsum tau shunt kuj.

Thaum ua hauj lwm nrog capacitors thiab electronics, tsis txhob hnov qab txog cov cai ntawm tus kheej kev ruaj ntseg thiab cov kev hem thawj ntawm hluav taws xob poob siab.
