Pali makamaka njira zotsatirazilithiamu batirekuchuluka kwa magetsi:
Njira yowonjezera:
Kugwiritsa ntchito boost chip:iyi ndiye njira yodziwika kwambiri yolimbikitsira. Chip chowonjezera chimatha kukweza mphamvu yotsika ya batri ya lithiamu kupita kumagetsi ofunikira. Mwachitsanzo, ngati mukufuna kuwonjezera3.7V lithiamu batirevoteji kuti 5V kupereka mphamvu kwa chipangizo, mungagwiritse ntchito kulimbikitsa chip choyenera, monga KF2185 ndi zina zotero. Tchipisi izi zimakhala ndi kutembenuka kwakukulu, zimatha kukhazikika pakusintha kwa voliyumu pakutulutsa kwamagetsi owonjezera, zotumphukira zake ndizosavuta, zosavuta kupanga ndikugwiritsa ntchito.
Kutengera ma transformer ndi mabwalo ofananira:Mphamvu yamagetsi yamagetsi imachitika kudzera mu mfundo yamagetsi yamagetsi yamagetsi yamagetsi. Kutulutsa kwa DC kwa batri ya lithiamu kumatembenuzidwa koyamba kukhala AC, ndiye magetsi amawonjezeka ndi transformer, ndipo pamapeto pake AC imakonzedwanso kubwerera ku DC. Njirayi ingagwiritsidwe ntchito nthawi zina ndi magetsi apamwamba komanso mphamvu zamagetsi, koma mapangidwe a dera ndi ovuta, aakulu komanso okwera mtengo.
Kugwiritsa ntchito pompa:charge pump ndi dera lomwe limagwiritsa ntchito ma capacitor ngati zinthu zosungira mphamvu kuti zizindikire kutembenuka kwamagetsi. Ikhoza kuchulukitsa ndi kukweza mphamvu ya batri ya lithiamu, mwachitsanzo, kukweza mphamvu ya 3.7V kumagetsi owirikiza kawiri kapena kuchulukitsa. Charge mpope dera lili ndi ubwino wokwera kwambiri, kukula kochepa, mtengo wotsika, woyenera malo ena apamwamba komanso zofunikira pazida zazing'ono zamagetsi.
Njira Zopangira Bucking:
Gwiritsani ntchito buck chip:Buck chip ndi gawo lapadera lophatikizika lomwe limatembenuza ma voliyumu apamwamba kukhala otsika. Zamabatire a lithiamu, magetsi ozungulira 3.7V nthawi zambiri amachepetsedwa kukhala voteji yotsika monga 3.3V, 1.8V kuti akwaniritse zofunikira zamagetsi zamagetsi zosiyanasiyana. Tchipisi wamba wamba monga AMS1117, XC6206 ndi zina zotero. Posankha buck chip, muyenera kusankha molingana ndi zomwe zikuchitika pano, kusiyana kwamagetsi, kukhazikika ndi magawo ena.
Series resistance voltage divider:njira imeneyi ndi kulumikiza resistor mu mndandanda mu dera, kuti mbali ya voteji akutsikira pa resistor, motero kuzindikira kuchepetsa lifiyamu batire voteji. Komabe, mphamvu yochepetsera voteji ya njirayi sikhazikika kwambiri ndipo idzakhudzidwa ndi kusintha kwa katundu wamakono, ndipo resistor idzadya mphamvu zambiri, zomwe zimapangitsa kuti mphamvu ziwonongeke. Chifukwa chake, njira iyi nthawi zambiri imakhala yoyenera pazochitika zomwe sizifuna kulondola kwamagetsi apamwamba komanso kutsitsa kwakanthawi kochepa.
Linear voltage regulator:Linear voltage regulator ndi chipangizo chomwe chimazindikira kutulutsa kwamagetsi kokhazikika posintha kuchuluka kwa ma transistor. Itha kukhazikika voteji ya batri ya lithiamu mpaka pamtengo wofunikira, yokhala ndi voliyumu yokhazikika, phokoso lotsika ndi zabwino zina. Komabe, kuyendetsa bwino kwa mzere wowongolera kumakhala kochepa, ndipo kusiyana pakati pa kulowetsa ndi kutulutsa mphamvu kumakhala kwakukulu, padzakhala kutaya mphamvu zambiri, zomwe zimabweretsa kutentha kwakukulu.
