A DC unikezelo lwamandlayinxalenye ebalulekileyo yezixhobo zombane neesistim ezahlukeneyo. Ibonelela ngobonelelo oluzinzileyo noluzinzileyo lwamandla ombane othe ngqo wangoku (DC) kumbane weesekethe zombane kunye namalungu. Ngokungafaniyo nombane otshintshayo (AC) wangoku, oguquguqukayo kumbane kunye necala,Unikezelo lwamandla eDCukuhambisa ukuhamba okuhambelanayo kwamandla ombane kwicala elinye. Eli nqaku lijonge ukuphonononga imiba esisiseko yeUnikezelo lwamandla eDC, izicelo zabo, kunye neentlobo ezahlukeneyo ezikhoyo kwimarike.
Unikezelo lwamandla eDCzisetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa uvavanyo lombane, uthungelwano ngomnxeba, i-industrial automation, kunye nophando lwezenzululwazi. Ngokuqhelekileyo baqeshwe kwiilabhoratri zombane kunye nezixhobo zokuvelisa amandla kunye nokuvavanya izixhobo zombane kunye neesekethe. Ukongeza,Unikezelo lwamandla eDCzisetyenziswa kwii-elektroniki ezahlukeneyo zabathengi, njengeelaptops, ii-smartphones, kunye nezixhobo zombane eziphathwayo. Ezi zibonelelo zombane zikwabalulekile ekunikeni amandla izithuthi zombane, iinkqubo zamandla ahlaziyekayo, kunye neziseko zonxibelelwano ngomnxeba.
Kukho iintlobo ezininzi zeUnikezelo lwamandla eDCekhoyo, nganye iyilelwe usetyenziso kunye neemfuno ezithile. UmgcaUnikezelo lwamandla eDCziyaziwa ngokulula kwazo kunye nokuthembeka, ukubonelela nge-voltage ephumayo ezinzileyo kunye nengxolo encinci yombane. UkutshintshaUnikezelo lwamandla eDC, ngakolunye uhlangothi, zisebenza kakuhle kwaye zihlangene, zibenza zilungele izicelo apho indawo kunye nokusebenza kwamandla kubalulekile. IyacwangciswaUnikezelo lwamandla eDCzibonelela ngeempawu eziphambili ezinjengolawulo olukude, amandla ombane kunye nenkqubo yangoku, kunye nohlengahlengiso oluchanekileyo lweziphumo, luzenza zilungele uphando kunye nophuhliso lweemeko.
Umgaqo osisiseko aDC unikezelo lwamandlaibandakanya ukuguqula amandla ombane e-AC ukusuka kumthombo wamandla ongundoqo ukuya kwimveliso ye-DC ezinzileyo. Le nkqubo yokuguqula ibandakanya ukulungiswa, ukuhluzwa, kunye nolawulo lombane. Kwinqanaba lokulungiswa, amandla ombane e-AC aguqulwa abe yi-voltage ye-DC esebenzayo kusetyenziswa iidiode. Emva koko, ukuhluzwa kusetyenziswa i-capacitors ukunciphisa i-ripple kunye nokuguquguquka kumbane wokuphuma. Okokugqibela, inqanaba lolawulo lombane liqinisekisa ukuba amandla ombane aphumayo ahlala engaguquki, kungakhathaliseki umahluko kumbane wokufaka okanye iimeko zomthwalo.
Ukuququmbela,Unikezelo lwamandla eDCidlala indima ebalulekileyo ekunikeni amandla izixhobo zombane kunye neesistim kuwo wonke amashishini ahlukeneyo. Ukukwazi kwabo ukubonelela ngomthombo ozinzileyo kunye nongaguqukiyo wombane othe ngqo wangoku kubenza babaluleke kakhulu kuvavanyo lwe-elektroniki, ukuvelisa, kunye nombane wabathengi. Ngeentlobo ezahlukeneyo zeUnikezelo lwamandla eDCekhoyo, kuquka imigca, ukutshintsha, kunye nemifuziselo ecwangcisiweyo, abasebenzisi bangakhetha eyona ndlela ifanelekileyo ngokusekelwe kwiimfuno zabo ezithile. Ukuqonda imigaqo esisiseko yeUnikezelo lwamandla eDCkwaye izicelo zabo zibalulekile kwiinjineli, amagcisa, kunye nabathandi abasebenza ngeenkqubo zombane kunye nezixhobo.
