Uninzi lwabaguquleli be-DC-DC benzelwe ukuguqulwa kwe-unidirectional, kwaye amandla angahamba kuphela ukusuka kwicala lokufaka ukuya kwicala lemveliso.Nangona kunjalo, i-topology yazo zonke ii-voltage converters zinokutshintshwa zibe yi-bidirectional conversion, enokuvumela amandla ukuba abuyele umva ukusuka kwicala lokuphuma ukuya kwicala lokufaka.Indlela yokutshintsha zonke ii-diode ukuba zilawule ngokuzimeleyo ukulungiswa okusebenzayo.Umguquli we-bidirectional ungasetyenziswa kwizithuthi kunye nezinye iimveliso ezifuna ukunyanyiswa kokuvuselela.Xa isithuthi sisebenza, umguquli uya kunika amandla kumavili, kodwa xa i-braking, amavili aya kunika amandla kwi-converter ngokulandelelana.
Ukutshintsha isiguquli kunzima ngakumbi kwimbono ye-elektroniki.Nangona kunjalo, ngenxa yokuba iisekethe ezininzi zipakishwe kwiisekethe ezidibeneyo, iinxalenye ezimbalwa ziyafuneka.Kuyilo lwesekethe, Ukuze kuncitshiswe ingxolo yokutshintsha (EMI / RFI) kuluhlu oluvumelekileyo kwaye wenze i-high-frequency circuit isebenze ngokuzinzileyo, kuyimfuneko ukuyila ngononophelo isiphaluka kunye nokuhlelwa kweesekethe zangempela kunye namacandelo.Ukuba ekusetyenzisweni kwe-step-down, iindleko zokutshintsha umguquli ziphezulu kunomguquli womgca.Nangona kunjalo, ngenkqubela yoyilo lwetshiphu, ixabiso lokutshintsha isiguquli liyehla ngokuthe ngcembe.
Isiguquli se-DC-DC sisixhobo esifumana amandla ombane we-DC kwaye sibonelela ngemveliso yombane we-DC.I-voltage ephumayo ingaba mkhulu kune-voltage yegalelo kunye ne-vice versa.Ezi zisetyenziselwa ukufanisa umthwalo kunikezelo lwamandla.Isekethe elula ye-DC-DC yokuguqula iquka iswitshi elawula umthwalo wokudibanisa kunye nokuqhawula unikezelo lwamandla.
Okwangoku, abaguquleli be-DC basetyenziswa ngokubanzi kwiinkqubo zokuguqula amandla ezithuthi zombane, izithuthi zokucoca umbane, izithuthuthu zombane kunye nezinye izithuthi zombane.Zikwasetyenziswa ngokubanzi kwiifowuni eziphathwayo, MP3, iikhamera zedijithali, abadlali beendaba eziphathwayo kunye nezinye iimveliso.
