HoLEDho khanna potoloho ea phepelo ea motlakase ho ipapisitse le molao-motheo oa phokotso ea motlakase oa capacitor, molao-motheo oa phokotso ea motlakase o batla o le tjena: ha motlakase oa sinusoidal AC o sebelisoa ho potoloho ea capacitor, tefiso ho lipoleiti tse peli tsa capacitor le tšimo ea motlakase lipakeng tsa. lipoleiti ke mesebetsi ea nako. Ke ho re: boleng bo sebetsang le amplitude ea voltage le hona joale ho capacitor le tsona li latela molao oa Ohm. Ke hore, ha matla a motlakase le maqhubu a motlakase ho capacitor a tsitsitse, ho tla phalla hona joale e tsitsitseng ea sinusoidal AC. E nyenyane reactance ea capacitive ke, boleng bo boholo ba capacitance ke, 'me ho feta hona joale ho phalla ka capacitor ke. Haeba mojaro o loketseng o hokahantsoe letotong la capacitor, mohloli o fokotsehileng oa motlakase o ka fumanoa, o ka hlahisoang ka ho lokisoa, ho sefa le ho tsitsisa ha motlakase. Bothata bo lokelang ho hlokomeloa mona ke hore tsamaisong ena ea potoloho, capacitor e sebelisa matla feela potolohong, empa ha e sebelise matla, kahoo katleho ea potoloho ea capacitor buck e phahame haholo.

Hangata, potoloho e kholo ea ho khanna eaLEDphepelo ea motlakase e ipapisitseng le molao-motheo oa capacitor buck e tla etsoa ka Buck capacitor, potoloho e lekanyang ea hajoale, potoloho e lokisang filthara le "voltage stabilizing shunt circuit". Har'a bona, capacitor ea ho theoha e lekana le transformer ea mohato o theoha ka potoloho e tloaelehileng ea ho tsitsa ha motlakase, e amanang ka ho toba le potoloho ea motlakase ea AC 'me e jara hoo e batlang e le matla a matla a AC u, kahoo tšepe ea filimi capacitor ntle le polarity. e lokela ho khethoa. Nakong eo motlakase o butsoeng, e ka 'na ea e-ba tlhōrō ea tlhōrō ea boleng ba halofo e ntle kapa e mpe ea U. ka nako ena, hona joale hang-hang e tla ba kholo haholo. Ka hona, mohanyetsi oa hona joale oa moeli o hloka ho hokahanngoa letotong la potoloho ho netefatsa polokeho ea potoloho, e leng lona lebaka le ka sehloohong le etsang hore potoloho ea hona joale e fokotseheng e be ea bohlokoa. Litlhoko tsa moralo oa potoloho ea mochini o lokisang le sefe li tšoana le tsa potoloho e tloaelehileng ea phepelo ea motlakase e laoloang ke DC. Lebaka leo ka lona "voltage stabilizing shunt circuit e hlokahalang ke hore potolohong ea ho fokotsa motlakase, boleng bo sebetsang ba hona joale ke bo tsitsitseng mme ha bo amehe ke phetoho ea mojaro oa hona joale. Ka hona, potolohong ea ho tsitsa ha motlakase, ho lokela ho ba le potoloho ea shunt ho arabela phetoho ea mojaro oa hona joale.
