GudahaLEDwadida korontada ku salaysan mabda'a yaraynta danab capacitor, mabda'a yaraynta danab waa qiyaas ahaan sida soo socota: marka sahayda koronto AC sinusoidal u waxaa codsatay in wareegga capacitor ah, kharashka ku saabsan labada taarikada ee capacitor iyo beerta korontada u dhexeeya taarikada waa hawlaha waqtiga.Taasi waa in la yidhaahdo: qiimaha wax ku ool ah iyo baaxadda danab iyo hadda on capacitor sidoo kale raacaan sharciga Ohm.Taasi waa, marka baaxadda korantada iyo inta jeer ee korantadu ay go'an tahay, qulqulka AC sinusoidal deggan ayaa qulquli doona.Mar kasta oo ay yar tahay falcelinta kaabsitiga, waa sii weynaada qiimaha awoodda, iyo weynaanta hadda socda ee capacitor waa.Haddii culeys ku habboon uu si taxane ah ugu xiran yahay capacitor-ka, il koronto oo la dhimay ayaa la heli karaa, kaas oo lagu soo saari karo hagaajinta, shaandhaynta iyo xasilinta tamarta.Dhibaato u baahan in la ogaado halkan waa in nidaamka wareegga, capacitor kaliya uu isticmaalo tamarta wareegga, laakiin ma isticmaalo tamar, sidaas darteed waxtarka wareegga buck capacitor waa mid aad u sarreeya.

Sida caadiga ah, wareegga ugu weyn ee wadista eeLEDsahayda korantada ee ku salaysan mabda'a capacitor buck waxay ka koobnaan doontaa capacitor Buck, wareegga xaddidan ee hadda, hagaajinta wareegga filter iyo korantada xasilinta wareegga shunt.Waxaa ka mid ah, capacitor-ka-hoos u dhigma koronto-hoosaadka hoos-u-dhaca ee wareegga xasilinta tamarta caadiga ah, kaas oo si toos ah ugu xiran wareegga korantada AC oo u sita ku dhawaad ​​dhammaan tamarta AC u, sidaas darteed filimka birta ah ee birta ah iyada oo aan lahayn polarity waa in la doortaa.Waqtigan xaadirka ah marka korantada la shido, waxa laga yaabaa inay noqoto meesha ugu saraysa ee lagu qiimeeyo wareegga nuska togan ama taban ee U. wakhtigan, wakhtigan degdega ahi aad buu u weynaan doonaa.Sidaa darteed, iska caabiyaha xaddidan ee hadda jira wuxuu u baahan yahay in lagu xiro si taxane ah wareegga wareegga si loo hubiyo badbaadada wareegga, taas oo ah sababta ugu weyn ee xaddidaadda xaddidan ee hadda jirta lagama maarmaanka ah.Shuruudaha naqshadaynta ee rectifier iyo filter circuit waxay la mid yihiin kuwa caadiga ah ee DC-ga ee wareegga sahayda korontada ee nidaamsan.Sababta loo baahan yahay korantada xasilinta wareegga shunt waa in wareegga yaraynta korantada, qiimaha wax ku oolka ah ee hadda I uu yahay mid deggan oo aan saameyn ku yeelan isbeddelka culeyska hadda.Sidaa darteed, wareegga xasilinta korantada, waa inay jirtaa wareegga shunt si looga jawaabo isbeddelka hadda jira.
