Iziguquli eziningi ze-DC-DC zenzelwe ukuguqulwa okukodwa, futhi amandla angageleza kuphela ukusuka ohlangothini lokokufaka ukuya ohlangothini lokuphumayo.Kodwa-ke, i-topology yazo zonke iziguquli zama-voltage ezishintshayo zingashintshwa zibe ukuguqulwa kwe-bidirectional, okungavumela amandla ukuthi abuyele emuva esuka ohlangothini olukhiphayo aye ohlangothini lokokufaka.Indlela iwukushintsha wonke ama-diode ekulungiseni okusebenzayo okulawulwa ngokuzimela.Isiguquli esinezinhlangothi ezimbili singasetshenziswa ezimotweni nakweminye imikhiqizo edinga ukubhuleka okuvuselelayo.Lapho imoto isebenza, isiguquli sizonikeza amandla emasondweni, kodwa lapho ibhuleka, amasondo azonikeza amandla kusiguquli ngokushintshana.
Ukushintsha isiguquli kuyinkimbinkimbi kakhulu ngokombono we-electronics.Nokho, ngenxa yokuthi amasekhethi amaningi ahlanganiswe kumasekhethi ahlanganisiwe, kudingeka izingxenye ezimbalwa.Ekwakhiweni kwesekethe, Ukuze kuncishiswe umsindo oshintshayo (EMI / RFI) ebangeni elivumelekile futhi wenze isekethe ye-high-frequency isebenze ngokuzinza, kuyadingeka ukuklama ngokucophelela isekethe kanye nokuhlelwa kwamasekethe angempela kanye nezingxenye.Uma ekusetshenzisweni kokuya phansi, izindleko zokushintsha isiguquli ziphezulu kunalezo zesiguquli esiqondile.Kodwa-ke, ngokuqhubeka kokwakhiwa kwe-chip, izindleko zokushintsha isiguquli ziyehla kancane kancane.
Isiguquli se-DC-DC siyidivayisi ethola i-voltage yokufaka ye-DC futhi inikeza i-DC ephumayo kagesi.I-voltage ephumayo ingaba nkulu kune-voltage yokufaka futhi ngokuphambene nalokho.Lezi zisetshenziselwa ukufanisa umthwalo nokunikezwa kwamandla.Isekhethi elula ye-DC-DC converter iqukethe iswishi elawula umthwalo ukuze uxhume futhi unqamule ukunikezwa kwamandla.
Njengamanje, abaguquli be-DC basetshenziswa kabanzi ezinhlelweni zokuguqula amandla ezimoto zikagesi, izimoto zokuhlanza zikagesi, izithuthuthu zikagesi nezinye izimoto zikagesi.Zibuye zisetshenziswe kabanzi kumaselula, iMP3, amakhamera edijithali, izidlali zemidiya eziphathwayo neminye imikhiqizo.
