KweI-LEDukushayela isekethe yokunikezwa kwamandla ngokusekelwe kumgomo wokunciphisa amandla kagesi we-capacitor, umgomo wokunciphisa amandla kagesi ucishe kanje: lapho ugesi we-sinusoidal AC usetshenziswa kusekethe ye-capacitor, ukushaja kumapuleti amabili e-capacitor kanye nenkundla kagesi phakathi amapuleti ayimisebenzi yesikhathi.Okusho ukuthi: inani elisebenzayo kanye ne-amplitude ye-voltage kanye ne-current on capacitor nayo ilandela umthetho ka-Ohm.Okusho ukuthi, lapho i-voltage amplitude kanye nemvamisa ku-capacitor zilungiswa, i-AC ye-sinusoidal eqinile izogeleza.I-reactance ye-capacitive encane iwukuthi, inani elikhulu le-capacitance likhulu, futhi likhulu lamanje eligeleza nge-capacitor.Uma umthwalo ofanelekayo uxhunywe ochungechungeni ku-capacitor, umthombo we-voltage oncishisiwe ungatholakala, ongakhishwa ngokulungiswa, ukuhlunga kanye nokuqiniswa kwe-voltage.Inkinga okufanele iqashelwe lapha ukuthi kulesi simiso sesifunda, i-capacitor isebenzisa amandla kuphela kumjikelezo, kodwa ayidli amandla, ngakho-ke ukusebenza kahle kwe-capacitor buck circuit kuphezulu kakhulu.

Ngokuvamile, isifunda sokushayela esiyinhloko seI-LEDukunikezwa kwamandla okusekelwe kumgomo we-capacitor buck kuzokwakhiwa i-Buck capacitor, isifunda esinqunyelwe samanje, ukulungisa umjikelezo wesihlungi kanye ne-voltage stabilizing shunt circuit.Phakathi kwazo, i-capacitor eyehlayo ilingana ne-transformer eyehlayo kumjikelezo ojwayelekile wokuzinzisa kagesi, oxhunywe ngokuqondile kumjikelezo wokuphakela amandla we-AC futhi ithwala cishe wonke amandla kagesi we-AC u, ngakho-ke i-capacitor yefilimu yensimbi ngaphandle kwe-polarity. kufanele kukhethwe.Okwamanje lapho amandla avuliwe, kungase kube inani eliphakeme lenani eliphakeme lomjikelezo omuhle noma ongemuhle wengxenye ye-U. ngalesi sikhathi, umsinga osheshayo uzoba mkhulu kakhulu.Ngakho-ke, i-resistor ekhawula yamanje idinga ukuxhunywa ochungechungeni lwesekethe ukuze kuqinisekiswe ukuphepha kwesekethe, okuyisizathu esiyinhloko sokuthi kungani isekethe yamanje yokukhawulela ibalulekile.Izidingo zedizayini zesilungisi nesihlungi sesekethe ziyefana nalezo zesekethe yokuphakelwa kwamandla elawulwa yi-DC evamile.Isizathu sokuthi kungani i-voltage stabilizing shunt circuit iyadingeka ukuthi kumjikelezo wokunciphisa i-voltage, inani elisebenzayo le-current I lizinzile futhi alithinteki ngokushintsha komthwalo wamanje.Ngakho-ke, kumjikelezo wokuzinzisa i-voltage, kufanele kube nesifunda se-shunt ukuphendula ushintsho lwamanje lomthwalo.
