Ma capacitor apamwamba kwambiri a ceramic amathanso kugwiritsidwa ntchito ngati ma decoupling capacitors. Ma capacitor awa amapangidwa kuti azigwira ntchito pamagetsi apamwamba ndipo angagwiritsidwe ntchito kuwongolera kusintha kwamagetsi pamayendedwe oyendetsa kuti apewe kusokonezana komanso kuchepetsa kusokoneza kwapang'onopang'ono. Komabe, mitundu yeniyeni ndi zitsanzo za ma high voltage ceramic capacitors ziyenera kusankhidwa malinga ndi zofunikira za dera ndi mavoti / mavoti apano a zigawo zomwe zimagwiritsidwa ntchito pozungulira. Ndibwino kuti mufunsane ndi wopanga www.hv-caps.com kapena wogawa kuti muwonetsetse kuti osankhidwa apamwamba kwambiri a ceramic capacitor ndi oyenera kugwiritsidwa ntchito ngati decoupling capacitor pakugwiritsa ntchito kwake.
Nazi zitsanzo zazithunzi zozungulira zomwe zikuwonetsa kugwiritsa ntchito ma decoupling capacitor:
Pachithunzi chozungulira ichi, capacitor (C) ndi decoupling capacitor yomwe imalumikizidwa pakati pa magetsi ndi nthaka. Zimathandiza kuchotsa phokoso lapamwamba kwambiri kuchokera ku chizindikiro cholowetsa chomwe chimapangidwa chifukwa cha kusintha ndi zinthu zina.
2. Digital dera pogwiritsa ntchito decoupling capacitors
Chizindikiro Cholowetsa--| Dalaivala |----||---| Katundu |---Siginali Yotulutsa
Pachithunzi chozungulira ichi, ma decoupling capacitors awiri (C1 ndi C2) amagwiritsidwa ntchito, imodzi kudutsa dalaivala ndi ina kudutsa katundu. Ma capacitors amathandizira kuchotsa phokoso lopangidwa chifukwa cha kusintha, kuchepetsa kugwirizanitsa ndi kusokoneza pakati pa dalaivala ndi katundu.
3. Magetsi oyendera magetsi pogwiritsa ntchito
Pachithunzi chozungulira ichi, decoupling capacitor (C2) imagwiritsidwa ntchito kuwongolera kutulutsa kwamagetsi kwamagetsi. Zimathandizira kusefa phokoso lomwe limapangidwa mugawo lamagetsi ndikuchepetsa kuphatikizika ndi kusokoneza pakati pa dera ndi zida zomwe zimagwiritsa ntchito magetsi.
Zotsatirazi ndi zomwe mumafunsa pafupipafupi za "decoupling capacitors"
1) Kodi ma decoupling capacitors ndi chiyani?
Ma decoupling capacitor ndi zida zamagetsi zomwe zimathandiza kusefa phokoso lapamwamba komanso kusinthasintha kwamagetsi. Zogwirizana pakati pa njanji yamagetsi ndi nthaka, zimakhala ngati njira yochepetsera yochepetsera maulendo apamwamba mpaka pansi, zomwe zimachepetsa phokoso lomwe limalowa m'derali.
2) Kodi ma decoupling capacitors amagwira ntchito bwanji?
Decoupling capacitors amapanga mphamvu yanthawi yochepa yamagetsi othamanga kwambiri kuti asinthe pakati pa magetsi ndi njanji zapansi. Mwa kuthamangitsa mphamvu zama frequency apamwamba mpaka pansi, amatha kuchepetsa phokoso lamagetsi ndikuchepetsa kulumikizana kwa ma siginecha osiyanasiyana.
3）Kodi ma decoupling capacitor amagwiritsidwa ntchito pati?
Decoupling capacitors amagwiritsidwa ntchito kwambiri pazida zamagetsi monga ma microprocessors, ma frequency ophatikizika, ma amplifiers, ndi zamagetsi zamagetsi. Amagwiritsidwanso ntchito pamapulogalamu apamwamba kwambiri komanso komwe kutsika kwa ma sign-to-noise-ratio ndikofunikira.
4) Kodi shunting ya capacitor ndi chiyani?
Capacitor shunting ndi njira yolumikizira capacitor pakati pa node ziwiri mudera lamagetsi kuti muchepetse phokoso kapena kulumikizana pakati pawo. Nthawi zambiri amagwiritsidwa ntchito pochotsa ma capacitor ngati njira yopititsira patsogolo mphamvu zamagetsi ndikupondereza EMI.
5) Kodi ma decoupling capacitor amachepetsa bwanji phokoso lapansi?
Decoupling capacitors amachepetsa phokoso lapansi popereka njira yochepetsera yochepetsera ma siginecha apamwamba kwambiri mpaka pansi. Capacitor imagwira ntchito ngati gwero lamphamvu lanthawi yayitali ndipo imathandizira kuchepetsa kuchuluka kwa mphamvu zomwe zimatha kuyenda pansi pa ndege.
Inde, ma decoupling capacitor amatha kupondereza EMI pochepetsa kuchuluka kwa phokoso lambiri lomwe limalowa mderali. Amapereka njira yochepetsetsa yochepetsera ma siginecha apamwamba kwambiri kuti atsike, kuchepetsa kuchuluka kwa phokoso lomwe limatha kulumikizana ndi ma siginecha ena.
7) Chifukwa chiyani ma decoupling capacitor ndi ofunikira pamabwalo apakompyuta?
Ma decoupling capacitor amatenga gawo lofunikira pakupanga ma circuit circuit pochepetsa phokoso ndi kusinthasintha kwa magetsi komwe kungakhudze magwiridwe antchito. Amathandizira kusunga umphumphu wa chizindikiro, kuchepetsa EMI ndi phokoso lapansi, kuteteza ku kuwonongeka kwa magetsi, ndi kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
8.)
Phokoso lapamwamba kwambiri komanso kulumikizana kwa ma siginecha kungayambitse kuchepa kwa magwiridwe antchito komanso kudalirika pamabwalo apakompyuta. Zitha kuyambitsa kusokoneza kwa ma siginecha osafunikira, kuchepetsa malire a phokoso, ndikuwonjezera chiwopsezo cha kulephera kwadongosolo.
9）Kodi mumasankha bwanji ma decoupling capacitor oyenera pa pulogalamu yanu?
Kusankhidwa kwa ma decoupling capacitor kumatengera zofunikira zomwe zimagwiritsidwa ntchito ngati ma frequency osiyanasiyana, voliyumu yamagetsi, ndi mtengo wa capacitance. Zimadaliranso kuchuluka kwa phokoso lomwe liripo mu dongosolo ndi zovuta za bajeti.
10) Ubwino wogwiritsa ntchito ma capacitor odulira mu chipangizo chamagetsi ndi chiyani?
Ubwino wogwiritsa ntchito ma decoupling capacitors pazida zamagetsi umaphatikizapo mawonekedwe abwinoko a siginecha, kukhazikika kwadera, kuchepetsedwa kwa phokoso lamagetsi, komanso chitetezo ku EMI. Angathandizenso kuchepetsa phokoso lapansi ndikuwongolera kudalirika kwathunthu kwa dongosolo.
Izi ndi zitsanzo zochepa chabe zazithunzi zozungulira zomwe zimagwiritsa ntchito ma decoupling capacitors. Miyezo yeniyeni ya dera ndi decoupling capacitor yomwe imagwiritsidwa ntchito idzasiyana malinga ndi ntchito ndi zofunikira za dera.
