Nkhani zaposachedwa kwambiri pamsika wamagetsi ndikukhazikitsa ma module atsopano a DC-DC okhala ndi umisiri waluso komanso kapangidwe kake. Ndi mawonekedwe apadera monga kuchita bwino kwambiri komanso kachulukidwe, kuyika kwakukulu ndi kutulutsa, ndikuthandizira kutali, kuwongolera kusintha, ndi kuwongolera ma voliyumu otulutsa, gawoli limawonedwa ngati losintha masewera pamakampani.
Module ya DC-DC ndi chipangizo chogwiritsira ntchito zinthu zambiri zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana kuphatikizapo ma seva, zipangizo zosungiramo zinthu, mauthenga a deta ndi zipangizo zoyankhulirana zopanda zingwe, zipangizo zamakampani, zida, zida zowunikira, ndi zida zoyesera. Izi zimapangitsa kukhala gawo lofunikira lamagetsi amakono omwe amafunikira kasamalidwe koyenera komanso kodalirika.
Chimodzi mwazinthu zazikulu za module ya DC-DC ndikugwiritsa ntchito topology yotsogola m'makampani, ukadaulo wamakina ndi kapangidwe kake ka synchronous rectifier. Mapangidwe awa amatsimikizira kuti gawoli limagwira ntchito bwino kwambiri ndikuchepetsa EMI ndi phokoso. Kuonjezera apo, mapangidwewa amalola kuti mphamvu zowonjezereka ziperekedwe ku katundu, zomwe zimapangitsa kuti zikhale zoyenera kwa ntchito zopanda malo.
Kuyika kwa ma module ndi kutulutsa kwake kumapangitsa kuti ikhale yosinthika kuti igwirizane ndi ntchito zosiyanasiyana. Zapangidwa kuti zizigwira ntchito kuchokera kumagetsi olowera otsika mpaka 4.5V komanso mpaka 60V, kutengera mtundu. Kusinthasintha kumeneku kumapangitsa kuti gawoli ligwiritsidwe ntchito pazinthu zosiyanasiyana popanda kufunikira kwa zigawo zina zowonjezera kuti zigwirizane ndi magetsi olowera.
Module ya DC-DC imasinthidwanso kwambiri ndi chithandizo chothandizira kutali, kuwongolera ma switch, ndikusintha kwamagetsi. Zinthuzi zimalola kusakanikirana kosavuta ndi machitidwe omwe alipo kale ndikupereka zina zowonjezera ndi kuyang'anira ntchito. Mphamvu yotulutsa mphamvu imasinthidwa mkati mwazomwe zafotokozedwa, zomwe zimalola kuti gawoli ligwiritsidwe ntchito ndi katundu wosiyanasiyana, kuphatikiza zomwe zimafunikira kuwongolera bwino kwamagetsi.
Chinthu chinanso chofunikira cha module ya DC-DC ndikuchita bwino kwambiri, komwe kumatha kufika 96%. Kuchita bwino kumeneku sikungothandiza kuchepetsa mphamvu yogwiritsira ntchito mphamvu, komanso kumathandiza kuchepetsa kutentha kwa kutentha, komwe kuli kofunikira pamapulogalamu omwe amafunikira kuziziritsa.
Ponseponse, gawo la DC-DC ndilowonjezera kwatsopano pamsika wamagetsi, lomwe limapereka zida zapamwamba komanso luso lomwe limapangitsa kuti likhale losunthika komanso lothandiza pamagwiritsidwe osiyanasiyana. Kuchita kwake kwakukulu, kuyika kwakukulu ndi kutulutsa, ndi mawonekedwe apadera zimapangitsa kukhala chinthu chofunikira kwambiri pamagetsi amakono omwe amafunikira mphamvu zoyendetsera bwino komanso zodalirika. Ndi kukhazikitsidwa kwa gawo la DC-DC, opanga zamagetsi ndi opanga tsopano ali ndi chida chatsopano champhamvu chowathandiza kukwaniritsa zomwe msika ukukula.
