HauvLEDtsav tsheb fais fab mov Circuit Court raws li lub hauv paus ntsiab lus ntawm capacitor voltage txo, lub voltage txo txoj cai yog roughly raws li nram no: thaum ib tug sinusoidal AC fais fab mov u yog siv rau lub capacitor Circuit Court, tus nqi ntawm ob daim hlau ntawm lub capacitor thiab hluav taws xob teb ntawm cov phiaj yog cov haujlwm ntawm lub sijhawm.Qhov ntawd yog hais tias: tus nqi zoo thiab amplitude ntawm voltage thiab tam sim no ntawm capacitor kuj ua raws li Ohm txoj cai.Ntawd yog, thaum qhov voltage amplitude thiab zaus ntawm lub capacitor yog tsau, qhov ruaj khov sinusoidal AC tam sim no yuav ntws.Qhov me me ntawm capacitive reactance yog, qhov ntau dua tus nqi capacitance yog, thiab qhov ntau dua qhov tam sim no ntws los ntawm lub capacitor.Yog hais tias ib tug tsim nyog load yog txuas nrog nyob rau hauv series ntawm lub capacitor, ib tug txo voltage qhov twg los tau, uas yuav muab tau los ntawm rectification, filtering thiab voltage stabilization.Ib qho teeb meem uas yuav tsum tau pom ntawm no yog tias nyob rau hauv qhov system Circuit Court no, lub capacitor tsuas yog siv lub zog hauv Circuit Court, tab sis tsis siv lub zog, yog li qhov ua tau zoo ntawm lub capacitor puck Circuit Court yog siab heev.

Feem ntau, lub ntsiab tsav tsheb Circuit Court ntawmLEDfais fab mov raws li lub hauv paus ntsiab lus ntawm lub capacitor phaw yuav tsim los ntawm Buck capacitor, tam sim no limiting circuit, rectifying filter circuit thiab voltage stabilizing shunt circuit.Ntawm lawv, cov kauj ruam-down capacitor yog sib npaug rau cov kauj ruam-down transformer nyob rau hauv qhov zoo tib yam voltage stabilizing Circuit Court, uas yog ncaj qha mus rau AC fais fab mov Circuit Court thiab bears yuav luag tag nrho cov AC fais fab mov u, yog li cov hlau zaj duab xis capacitor tsis polarity. yuav tsum xaiv.Thaum lub sij hawm thaum lub hwj chim qhib, nws yuav yog lub ncov rau lub ncov tus nqi ntawm qhov zoo los yog tsis zoo ib nrab voj voog ntawm U. nyob rau lub sij hawm no, lub instantaneous tam sim no yuav loj heev.Yog li ntawd, tam sim no limiting resistor yuav tsum tau txuas nrog nyob rau hauv series nyob rau hauv Circuit Court kom muaj kev ruaj ntseg ntawm lub Circuit Court, uas yog lub ntsiab yog vim li cas vim li cas tam sim no limiting Circuit Court yog indispensable.Cov qauv tsim ntawm lub rectifier thiab lim Circuit Court yog tib yam li ntawm qhov zoo tib yam DC tswj fais fab mov Circuit Court.Yog vim li cas vim li cas thiaj li yuav tsum tau muaj qhov voltage stabilizing shunt Circuit Court yog tias nyob rau hauv qhov hluav taws xob txo Circuit Court, tus nqi zoo ntawm tam sim no kuv ruaj khov thiab tsis cuam tshuam los ntawm kev hloov pauv ntawm cov khoom tam sim no.Yog li ntawd, nyob rau hauv lub voltage stabilizing Circuit Court, yuav tsum muaj ib tug shunt Circuit Court los teb rau qhov kev hloov ntawm load tam sim no.
