Pane kunyanya zvinotevera nzira kutilithium bhatirikuwedzera voltage:
Boosting nzira:
Kushandisa boost chip:iyi ndiyo yakajairika nzira yekusimudzira. Iyo boost chip inogona kusimudza yakaderera voltage yelithium bhatiri kune inodiwa yakakwirira voltage. Semuenzaniso, kana iwe uchida kusimudza iyo3.7V lithium bhatirivoltage ku5V kupa simba kune mudziyo, unogona kushandisa yakakodzera boost chip, senge KF2185 zvichingodaro. Aya machipisi ane hunyanzvi hwekushandura, anogona kudzikamiswa kana iri shanduko yemagetsi ekuisa mukubuda kweiyo set boost voltage, iyo peripheral dunhu iri nyore, nyore kugadzira uye kushandisa.
Kutora transformer uye maseketi ane hukama:Boost voltage inowanikwa kuburikidza neiyo electromagnetic induction musimboti we transformer. Iyo DC inobuda yelithium bhatiri inotanga kushandurwa ku AC, ipapo iyo voltage inowedzerwa ne transformer, uye pakupedzisira iyo AC inogadziridzwa kudzokera kuDC. Iyi nzira inogona kushandiswa mune dzimwe nguva ine yakakwirira voltage uye simba zvinodiwa, asi dhizaini yedunhu yakaoma, yakakura uye inodhura.
Kushandisa pombi yekuchaja:pombi yekuchaja idunhu rinoshandisa ma capacitor sesimba rekuchengetedza zvinhu kuti uone kutendeuka kwemagetsi. Inogona kuwedzera uye kusimudza simba re lithiamu bhatiri, semuenzaniso, kusimudza voltage ye 3.7V kusvika kune voltage kaviri iyo kana yakawanda yakawanda. Charge pombi yedunhu ine zvakanakira kushanda kwepamusoro, saizi diki, mutengo wakaderera, wakakodzera kune imwe nzvimbo yepamusoro uye nehunyanzvi zvinodiwa zvemidziyo midiki yemagetsi.
Nzira dzekubvisa:
Shandisa buck chip:Buck chip idunhu rakakosha rakasanganiswa rinoshandura yakakwira voltage kuita yakaderera voltage. Forlithium mabhatiri, magetsi akapoteredza 3.7V anowanzo kuderedzwa kusvika kune yakaderera voltage se 3.3V, 1.8V kuti isangane nezvinodiwa zvemagetsi emagetsi akasiyana-siyana. Yakajairika buck machipisi anosanganisira AMS1117, XC6206 zvichingodaro. Paunosarudza buck chip, iwe unofanirwa kusarudza zvinoenderana neinobuda ikozvino, voltage musiyano, kugadzikana uye mamwe ma parameter.
Series resistance voltage divider:nzira iyi ndeyekubatanidza resistor munhevedzano mudunhu, kuitira kuti chikamu chevoltage chinodonha pane chinopikisa, nokudaro kuona kuderedzwa kwe lithium bhatiri voltage. Nekudaro, iyo voltage yekudzikisa mhedzisiro yeiyi nzira haina kugadzikana uye ichakanganiswa nekuchinja kwemutoro wazvino, uye resistor inopedza imwe huwandu hwesimba, zvichikonzera kupera kwesimba. Naizvozvo, iyi nzira inowanzokodzera chete kune zviitiko zvisingade yakakwira voltage kurongeka uye diki mutoro ikozvino.
Linear voltage regulator:Linear voltage regulator chishandiso chinoona yakagadzikana voltage kubuda nekugadzirisa conduction degree ye transistor. Inogona kudzikamisa iyo lithium bhatiri voltage pasi kune inodiwa voltage kukosha, ine yakagadzikana yekubuda voltage, yakaderera ruzha uye zvimwe zvakanaka. Nekudaro, kugona kweiyo linear regulator kwakadzikira, uye kana mutsauko uripo pakati pekupinza uye kubuda voltages wakakura, pachava nekurasikirwa kwesimba kwakawanda, zvichikonzera kukura kukuru kwekupisa.
