Otembenuza ambiri a DC-DC amapangidwira kutembenuka kwa unidirectional, ndipo mphamvu imatha kuyenda kuchokera kumbali yolowera kupita ku mbali yotulutsa.Komabe, topology ya ma switching voltage converters onse amatha kusinthidwa kukhala bidirectional conversion, yomwe imatha kulola mphamvu kuyenderera kuchokera kumbali yotuluka kupita ku mbali yolowera.Njira ndikusintha ma diode onse kuti aziwongolera paokha.The bidirectional converter itha kugwiritsidwa ntchito m'magalimoto ndi zinthu zina zomwe zimafuna kuyambiranso.Galimoto ikathamanga, chosinthiracho chidzapereka mphamvu ku mawilo, koma pobowola, mawilowo amapereka mphamvu kwa wosinthirayo.
Kusintha kosinthira kumakhala kovuta kwambiri kuchokera kuzinthu zamagetsi.Komabe, chifukwa mabwalo ambiri amaphatikizidwa mumayendedwe ophatikizika, magawo ochepa amafunikira.Pakukonza dera, Kuti muchepetse phokoso losinthira (EMI / RFI) kumalo ovomerezeka ndikupangitsa kuti ma frequency apamwamba azigwira ntchito mosasunthika, ndikofunikira kupanga mosamalitsa kuzungulira ndi kuyika mabwalo enieni ndi zigawo zake.Ngati mukugwiritsa ntchito njira yotsika, mtengo wosinthira masinthidwe ndi wapamwamba kuposa wosinthira mzere.Komabe, ndi kupita patsogolo kwa kapangidwe ka chip, mtengo wosinthira masinthidwe ukutsika pang'onopang'ono.
DC-DC converter ndi chipangizo chomwe chimalandira voteji ya DC ndipo chimapereka mphamvu ya DC.Mphamvu yotulutsa imatha kukhala yayikulu kuposa mphamvu yolowera komanso mosemphanitsa.Izi zimagwiritsidwa ntchito kuti zigwirizane ndi katundu ndi magetsi.Chigawo chosavuta cha DC-DC chosinthira chimakhala ndi chosinthira chomwe chimawongolera katundu kuti alumikizike ndikuchotsa magetsi.
Pakadali pano, otembenuza a DC amagwiritsidwa ntchito kwambiri pamakina osinthira mphamvu zamagalimoto amagetsi, magalimoto oyeretsa magetsi, njinga zamoto zamagetsi ndi magalimoto ena amagetsi.Amagwiritsidwanso ntchito kwambiri m'mafoni am'manja, MP3, makamera a digito, osewera atolankhani ndi zinthu zina.
