Doorka Chip Capacitors

Ka gudub

Capacitor bypass waa aalad kaydisa tamarta oo siisa tamar aaladda maxalliga ah, taas oo xattaa soo saarta wax-soo-saarka nidaamiyaha oo yareeya baahida culeyska.Sida batari yar oo dib lagu dallaci karo, capacitor-ka dhaafa waa lagu dalaci karaa oo lagu sii dayn karaa qalabka.Si loo yareeyo is-hortaagga, capacitor-ka dhaafka waa in la dhigaa sida ugu dhow ee suurtogalka ah biinka korantada iyo biinka dhulka ee aaladda rarka.Tani waa hab wanaagsan oo looga hortagayo kor u kaca suurtagalka ah ee dhulka iyo buuqa ay sababto qiyamka wax gelinta ee xad dhaafka ah.Awooda dhulku waa hoos u dhaca danab ee xidhiidhka dhulka marka la dhex marayo burka hadda sare.

Kala goynta

Goynta, oo sidoo kale loo yaqaan kala goynta.Xaga wareegga mar walba waxa lagu kala saari karaa isha la wado iyo culayska la wado.Haddii capacitance load uu yahay mid aad u weyn, wareegga wadista waa in ay dallacaan oo ay sii daayaan capacitor si ay u dhamaystiraan boodka signal, iyo hadda waa ka weyn yahay marka cidhifka kor u kacaya waa steeper, si hadda la kexeeyey nuugi doonaa hadda sahayda weyn, iyo sabab u ah. in inductance ee wareegga, iska caabin ah (gaar ahaan inductance on pin chip, kaas oo dhalin doona bounce a), hadda tani dhab ahaantii waa buuq la xidhiidha xaaladda caadiga ah, taas oo saamayn doonta marxaladda hore Tani waa waxa loogu yeero " isku xidhka”.

Kapacitor-ka isku xidhka ayaa ah inuu ciyaaro doorka "batteriga", si uu ula kulmo isbeddellada hadda ee wareegga wadista, si looga fogaado faragelinta isku-xirnaanta labada dhinac.

Isku-dubbaridka capacitor-ka-dhaafka ah iyo kaabcitor-ka-goynta ayaa fududaan doonta in la fahmo.Kapacitor-ka dhaafka dhab ahaantii waa kala goynaysaa, laakiin capacitor-ka dhaafka guud ahaan waxa uu tilmaamayaa soo noqnoqoshada sare ee soo noqnoqoshada, taas oo ah in la hagaajiyo dariiqa dheecaanka impedance hoose ee dhawaaqa beddelka soo noqnoqda.Capacitor-soo noqnoqoshada sare ee dhaafitaanka guud ahaan waa yar yahay, marka loo eego inta jeer ee resonant waxaa guud ahaan la qaataa 0.1μF, 0.01μF, iwm.;halka awoodda capacitor decoupling guud ahaan ka weyn yahay, laga yaabaa in 10μF ama ka weyn, marka loo eego xuduudaha qaybinta ee wareegga, iyo cabbirka isbeddelka ee drive hadda si loo go'aamiyo.Bypass waa in la shaandheeyo faragelinta calaamadda wax-soo-gelinta, halka kala-goynta ay tahay in la shaandheeyo faragelinta calaamadda wax-soo-saarka si looga hortago in calaamadda faragelintu ku soo noqoto sahayda korontada.Tani waa inay noqotaa farqiga lama huraanka ah ee u dhexeeya.

Shaandhaynta

Aragti ahaan (tusaale, iyadoo loo malaynayo in capacitor-ku uu saafi yahay), kobaca awooddu, way sii yaraanaysaa xannibaadda iyo kor u kaca inta jeer ee uu dhex maraayo.Laakiin ficil ahaan, inta badan capacitors in ka badan 1μF waa capacitors electrolytic, kuwaas oo leh qayb weyn inductive, sidaas impedance kordhin doonaa halkii ka dib markii inta jeer waa sare.Mararka qaarkood waxaad arki kartaa capacitance weyn oo korontolytic capacitor barbar socda capacitor yar, marka capacitor weyn iyada oo inta jeer ee hooseeya, capacitor yar iyada oo inta jeer ee sare.Doorka capacitance waa in la dhaafo iska caabin sare oo hooseeya, iyada oo loo marayo iska caabin badan oo soo noqnoqonaya oo hooseeya.Inta uu sii weynaado awoodda, waa ay fududahay in la dhaafo inta jeer ee hooseeya.Si gaar ah loogu isticmaalo shaandhaynta, capacitor weyn (1000μF) shaandheeya soo noqnoqoshada hooseeya, capacitor yar (20pF) filter soo noqnoqoshada sare.Isticmaalayaasha qaar ayaa si male-awaal ah u barbardhigay capacitor filtarka iyo "balliga biyaha".Mar haddii korantada labada daraf ee capacitor-ku aanu si kedis ah isu beddelin, waxa la arki karaa in mar kasta oo uu kor u kaco soo noqnoqoshada ishaadu, ay sii badanayso yaraanta, taas oo si garaaf ahaan loo odhan karo capacitor-ku waa sida balli-biyood oo kale, oo aanay sababin a dhawr dhibcood oo biyo ah si ay ugu biiraan ama uga baxaan isbeddelka mugga biyaha.Waxay u beddeshaa isbeddelka danab beddelka isbeddelka hadda, iyo inta jeer ee sarreeya, waa sarreeyaa hadda ugu sarreeya, sidaas awgeedna korantada.Shaandhaynta waa habka dallacaadda, dallacaadda.

Kaydinta tamarta

Capacitor-ka kaydinta tamarta waxa uu ku soo dalacayaa rectifier waxana uu ku wareejiyaa tamarta kaydsan iyada oo loo sii marinayo beddelaha waxa ay keentaa soo saarida sahayda korontada.Aluminium electrolytic capacitors oo leh qiimaynta danab ee 40 ilaa 450 VDC iyo qiyamka awooda inta u dhaxaysa 220 iyo 150,000 μF (sida B43504 ama B43505 ee EPCOS) ayaa inta badan la isticmaalaa.Iyada oo ku xidhan shuruudaha bixinta korantada, aaladaha mararka qaarkood waxay ku xidhan yihiin si taxane ah, barbar socda ama isku dhafan.Sahayda korantada ee leh heer awood ka badan 10 kW, capacitors terminal caado ka weyn ayaa badanaa la isticmaalaa.
