Mu dziko la machitidwe amphamvu, Alternating current (AC) ndi Direct current (DC) ndi mitundu iwiri yofala ya magetsi. AC ndi current yomwe imasintha njira nthawi zonse, pomwe DC ndi current yomwe imayenda nthawi zonse mbali imodzi. Posankha magetsi, tingasankhe pakati pa AC ndi DC kapena DC Kupita ku DC malinga ndi zosowa zathu.


Mphamvu yamagetsi ya AC/DC ndi chipangizo chomwe chimasintha AC kukhala DC. Kusinthika kumeneku nthawi zambiri kumachitika kudzera mu kukonzanso. Chosinthira magetsi chimasintha mphamvu ya AC kukhala mphamvu ya DC yokhala ndi njira yolunjika nthawi zonse. Ma diode amagwiritsidwa ntchito kwambiri mu zosinthira magetsi chifukwa zimangolola mphamvu kuyenda mbali imodzi. Chosinthira magetsi chingakhale chosinthira magetsi theka kapena chosinthira magetsi lonse. Zosinthira magetsi theka zimalola theka la kayendedwe ka AC kudutsa, pomwe zosinthira magetsi zonse zimalola kayendedwe konse ka AC kudutsa. Ma capacitor nthawi zambiri amagwiritsidwa ntchito limodzi ndi zosinthira magetsi kuti ziwongolere mphamvu ya DC yotuluka.


Mphamvu yamagetsi ya DC/DC ndi chipangizo chomwe chimasintha DC kukhala ma voltage osiyanasiyana kapena ma current levels. Kusintha kumeneku nthawi zambiri kumachitika kudzera mu DC-DC converter.

Chosinthira cha DC-DC chingakweze kapena kutsitsa voteji yolowera kuti chipereke voteji yotulutsa yapamwamba kapena yotsika. Chingakwezenso kapena kutsitsa voteji yolowera kuti chipereke voteji yotulutsa yapamwamba kapena yotsika. Osinthira a DC-DC nthawi zambiri amagwiritsa ntchito ukadaulo wamagetsi osinthira. Zipangizo zamagetsi zosinthira zimagwiritsa ntchito zida zosinthira, monga ma transistors kapena ma MOSFET, kuti ziwongolere kuyenda kwa magetsi. Polamulira nthawi yosinthira ndi kuchuluka kwa zida izi, mphamvu yamagetsi kapena kusintha kwa magetsi komwe mukufuna kumatha kuchitika.


Zipangizo zamagetsi za AC kupita ku DC ndi DC kupita ku DC zimagwiritsidwa ntchito mosiyanasiyana m'njira zosiyanasiyana. Zipangizo zamagetsi za AC/DC zimagwiritsidwa ntchito kwambiri m'zida zapakhomo, zida zamagetsi, ndi makompyuta omwe amafunikira mphamvu za DC.

Kumbali inayi, magetsi ochokera ku DC kupita ku DC amagwiritsidwa ntchito kwambiri m'magalimoto amagetsi, ma solar panels, ndi zida zolumikizirana zopanda zingwe zomwe zimafuna magetsi osiyanasiyana kapena milingo yamagetsi. Magetsi ochokera ku AC kupita ku DC ndi magetsi ochokera ku DC mwachindunji amachita gawo lofunikira kwambiri m'makina amagetsi, zomwe zimatilola kupereka magetsi okhazikika komanso odalirika pansi pa zofunikira zosiyanasiyana zamagetsi.

Mwachidule, magetsi ochokera ku AC kupita ku DC ndi magetsi ochokera ku DC ndi ofala kwambiri m'makina amagetsi, zomwe zimatipatsa mphamvu yokhazikika komanso yodalirika.
