Kukhona ikakhulukazi izindlela ezilandelayo foribhethri ye-lithiumukuthuthukiswa kwe-voltage:
Indlela yokuthuthukisa:
Ukusebenzisa i-boost chip:lena yindlela evame kakhulu yokuthuthukisa. I-boost chip ingakhuphula i-voltage ephansi yebhethri ye-lithium iye ku-voltage ephakeme edingekayo. Isibonelo, uma ufuna ukukhulisa i-Ibhethri ye-lithium engu-3.7VI-voltage eya ku-5V ukuze unikeze amandla kudivayisi, ungasebenzisa i-chip yokuthuthukisa efanelekile, njenge-KF2185 njalonjalo. Lawa ma-chips asebenza kahle kakhulu ekuguquleni, angaqiniswa esimweni sokushintsha kwe-voltage yokufaka ekuphumeni kwe-set boost voltage, isifunda se-peripheral silula, kulula ukuklama nokusebenzisa.
Ukwamukela i-transformer namasekethe ahlobene:I-Boost voltage yenziwa ngomgomo wokungeniswa kwe-electromagnetic we-transformer. Ukukhishwa kwe-DC kwebhethri ye-lithium kuqala kuguqulelwa ku-AC, bese i-voltage ikhuliswa yi-transformer, futhi ekugcineni i-AC ilungiswa ibuyele ku-DC. Le ndlela ingase isetshenziswe kwezinye izikhathi ngezidingo zamandla kagesi aphezulu kanye namandla, kodwa umklamo wesifunda uyinkimbinkimbi, mkhulu futhi uyabiza.
Ukusebenzisa iphampu yokushaja:iphampu yokushaja iyisekhethi esebenzisa ama-capacitor njengezinto zokugcina amandla ukuze ibone ukuguqulwa kwamandla kagesi. Ingakwazi ukuphindaphinda futhi iphakamise i-voltage yebhethri ye-lithium, isibonelo, ukuphakamisa i-voltage engu-3.7V ku-voltage ephindwe kabili leyo noma i-multiple ngaphezulu. Isekhethi yephampu yokushaja inezinzuzo zokusebenza kahle okuphezulu, usayizi omncane, izindleko eziphansi, ezifanele ezinye zezindawo eziphezulu kanye nezidingo ezisebenza kahle zamadivayisi amancane kagesi.
Izindlela ze-Bucking:
Sebenzisa i-buck chip:I-Buck chip iyisekhethi ekhethekile ehlanganisiwe eguqula i-voltage ephezulu ibe yi-voltage ephansi. Ngobaamabhethri e-lithium, i-voltage ezungeze u-3.7V imvamisa yehliswa ibe amandla kagesi aphansi njenge-3.3V, 1.8V ukuze ihlangabezane nezimfuneko zokuphakelwa kwamandla ezingxenyeni ezihlukahlukene ze-elekthronikhi. Ama-buck chips ajwayelekile afaka i-AMS1117, XC6206 njalonjalo. Lapho ukhetha i-chip buck, udinga ukukhetha ngokuya ngokuphuma kwamanje, umehluko we-voltage, ukuzinza neminye imingcele.
Isihlukanisi se-voltage yokumelana nochungechunge:le ndlela iwukuxhuma i-resistor ochungechungeni kumjikelezo, ukuze ingxenye ye-voltage iwele ku-resistor, ngaleyo ndlela ibone ukuncishiswa kwe-lithium battery voltage. Kodwa-ke, umphumela wokunciphisa i-voltage wale ndlela awuzinzile kakhulu futhi uzothinteka izinguquko kumthwalo wamanje, futhi i-resistor izodla inani elithile lamandla, okuholela ekulahlekeni kwamandla. Ngakho-ke, le ndlela ngokuvamile ifaneleka kuphela ezenzakalweni ezingadingi ukunemba kwe-voltage ephezulu kanye nomthwalo omncane wamanje.
I-Linear voltage regulator:I-Linear voltage regulator iyisisetshenziswa esibona ukuphuma kwamandla kagesi ezinzile ngokulungisa izinga lokuqhuba kwe-transistor. Ingakwazi ukuzinzisa i-lithium yebhethri ye-lithium yehle ibe yinani le-voltage edingekayo, nge-voltage ephumayo ezinzile, umsindo ophansi nezinye izinzuzo. Kodwa-ke, ukusebenza kahle kwesilawuli somugqa kuphansi, futhi uma umehluko phakathi kwama-voltage okokufaka nokuphumayo mkhulu, kuzoba nokulahlekelwa kwamandla amaningi, okuholela ekukhiqizeni ukushisa okukhulu.
