I-chip yokuphatha amandla i-IC iyisikhungo sokuphakela amandla kanye nesixhumanisi sayo yonke imikhiqizo ye-elekthronikhi namathuluzi, ebhekele ukuguqulwa, ukusatshalaliswa, ukutholwa kanye neminye imisebenzi yokulawula amandla adingekayo, iyithuluzi elibalulekile elibalulekile lemikhiqizo namathuluzi kagesi.Ngesikhathi esifanayo, ngokuthuthukiswa kwe-inthanethi Yezinto, amandla amasha, ubuhlakani bokwenziwa, amarobhothi kanye nezinye izinkambu zezicelo ezisafufusa, imakethe ephansi yokulawulwa kwamandla yangenisa amathuba amasha okuthuthukisa.Okulandelayo ukwethula ukuhlukaniswa, ukusetshenziswa kanye nokwahlulela kwamakhono ahlobene ne-IC chip yokuphatha amandla.
Ukuhlukaniswa kwe-chip yokuphatha amandla
Ngokwengxenye ngenxa yokwanda kwe-ics yokuphatha amandla, ama-semiconductors kagesi aqanjwe kabusha ngokuthi ama-semiconductors okuphatha amandla.Kungenxa yokuthi amasekethe amaningi ahlanganisiwe (IC) emkhakheni wokuphakelwa kukagesi, abantu bangaphezu kwamandla okuphatha ukubiza isigaba samanje sobuchwepheshe bokuhlinzekwa kwamandla.I-semiconductor yokuphathwa kwamandla engxenyeni ehamba phambili ye-IC yokuphatha amandla, ingafinyezwa njengokulandelayo 8.
1. AC/DC modulation IC.Iqukethe i-low voltage control circuit kanye ne-high voltage switching transistor.
2. DC/DC modulation IC.Kufaka phakathi izilawuli ze-boost/step-down, namaphampu wokushaja.
3. Ukulawula isici samandla i-PFC eyenziwe sengathi i-IC.Nikeza isekethe yokufaka amandla ngomsebenzi wokulungisa isici samandla.
4. ukuguqulwa kwe-pulse noma i-pulse amplitude modulation PWM/PFM control IC.Isilawuli sokuguquguquka kwefrikhwensi ye-pulse kanye/noma noma isilawuli sokushintshwa kobubanzi be-pulse sokushayela amaswishi angaphandle.
5. i-linear modulation IC(njenge-linear low voltage regulator LDO, njll.).Kufaka phakathi izilawuli eziya phambili nezingezinhle, kanye namashubhu okushintsha amandla kagesi aphansi we-LDO.
6. ukushajwa kwebhethri nokuphatha i-IC.Lokhu kufaka phakathi ukushajwa kwebhethri, ukuvikela kanye nezibonisi zamandla, kanye nama-ics ebhethri “ahlakaniphile” okuxhumana kwedatha yebhethri.
7. I-IC yokulawula ibhodi eshintshashintshayo eshisayo (ikhululiwe ethonyeni lokufaka noma lokususa esinye isixhumi esibonakalayo ohlelweni lokusebenza).
8. Umsebenzi wokushintsha we-MOSFET noma we-IGBT IC.
Phakathi kwalezi zi-ic zokuphatha amandla, i-voltage regulation ICS ikhula ngokushesha futhi ikhiqiza kakhulu.Ama-ics okuphatha amandla ahlukahlukene ngokuvamile ahlotshaniswa nenani lezinhlelo zokusebenza ezihlobene, ngakho-ke izinhlobo eziningi zamadivayisi zingafakwa kuhlu lwezinhlelo zokusebenza ezahlukene.
Okwesibili, ukusetshenziswa kwe-chip yokuphatha amandla
Ububanzi bokuphathwa kwamandla banzi uma kuqhathaniswa, okuhlanganisa hhayi kuphela ukuguqulwa kwamandla okuzimele (ikakhulukazi i-DC kuya ku-DC, okuyi-DC/DC), ukusatshalaliswa kwamandla okuzimele nokutholwa, kodwa futhi ukuguqulwa kwamandla okuhlanganisiwe kanye nesistimu yokuphatha amandla.Ngokunjalo, ukuhlukaniswa kwe-chip yokuphatha amandla kuhlanganisa nalezi zici, njenge-linear power chip, i-voltage reference chip, i-switching power chip, i-LCD driver chip, i-LED driver chip, i-voltage chip chip, i-chip yokuphatha ukushaja kwebhethri nokunye.
Uma idizayini yesekethe yokunikezwa kwamandla okunomsindo omkhulu nokucindezelwa kwe-ripple, icelwa ukuthi ithathe indawo encane ye-PCB (isb, omakhalekhukhwini neminye imikhiqizo ye-elekthronikhi ephathwa ngesandla), isekethe yokuphakelwa kwamandla kagesi ayivunyelwe ukusebenzisa i-inductor (efana nomakhalekhukhwini) , ukulinganisa okudlulayo kanye namandla ombuso okukhiphayo kudinga umsebenzi wokuzihlola, ukwehla kwengcindezi okudingekayo kokuqiniswa kwe-voltage kanye nokusetshenziswa kwayo okuphansi kwamandla, ulayini wezindleko eziphansi nesixazululo esilula, Khona-ke ukunikezwa kwamandla omugqa kuyisinqumo esifanele kakhulu.Lokhu kunikezwa kwamandla kuhlanganisa lobu buchwepheshe obulandelayo: ireferensi ye-voltage enembayo, ukusebenza okuphezulu, isikhulisi sokusebenza somsindo ophansi, isilawuli sokwehla kwamandla kagesi aphansi, amandla aphansi amile.
Ngokungeziwe ku-chip yokuguqula amandla eyisisekelo, i-chip yokuphatha amandla ihlanganisa ne-chip yokulawula amandla ngenjongo yokusebenzisa amandla okunengqondo.Njenge-chip yebhethri ye-NiH ehlakaniphile esheshayo yokushaja, i-lithium ion ibhethri yokushaja kanye ne-chip yokulawula ukukhipha, ibhethri ye-lithium ion phezu kwe-voltage, phezu kwamanje, ngaphezu kwezinga lokushisa, i-chip yokuvikela isifunda esifushane;Kulayini wokunikezwa kwamandla kanye ne-chip yokulawula ukushintsha kwebhethri eyisipele, i-chip yokulawula amandla e-USB;Iphampu yokushaja, ukunikezwa kwamandla kagesi we-LDO enamashaneli amaningi, ukulawula ukulandelana kwamandla, ukuvikela okuningi, ukushajwa kwebhethri nokuphathwa kokukhipha amandla chip eyinkimbinkimbi, njll.
Ikakhulukazi kuma-electronics omthengi.Isibonelo, i-DVD ephathekayo, iselula, ikhamera yedijithali nokunye, cishe ngezingcezu ezingu-1-2 ze-chip yokuphatha amandla ingahlinzeka ngokuhlinzeka kwamandla okuyinkimbinkimbi, ukuze ukusebenza kwesistimu kube kuhle kakhulu.
Okwesithathu, i-motherboard power management chip amakhono okwahlulela okuhle noma okubi
I-Motherboard power management chip ibaluleke kakhulu i-motherboard, siyazi ukuthi ingxenye yomsebenzi ukuhlangabezana nalesi simo, enye i-voltage, enye ingamandla.I-chip ye-motherboard yokuphatha amandla inesibopho se-voltage yengxenye ngayinye ye-chip ye-motherboard.Uma i-motherboard embi ibekwa phambi kwethu, singakwazi kuqala ukuthola i-chip yokuphatha amandla ebhodini lomama futhi sibone ukuthi i-chip inawo yini amandla okukhipha amandla.
I-1) Okokuqala nje ngemva kokuphulwa kwe-chip yokuphatha amandla ebhodi elikhulu, i-CPU ngeke isebenze, okusho ukuthi, ngeke kube khona izinga lokushisa ngemuva kokuthi i-mainboard inikwe amandla ku-CPU, kulokhu ungasebenzisa impompi ye-diode yemitha. ukuhlola ukumelana kwekhoyili ye-inductor kanye nomhlabathi uma imitha yehla inani lokumelana likhuphuka ukuze lifakazele ukuthi i-chip yokuphatha amandla inhle, ngokuphambene nalokho, kunenkinga.
2) Uma ukunikezwa kwamandla we-peripheral kuyinto evamile kodwa i-voltage ye-chip yokuphatha amandla ingavamile, ungahlola kuqala i-voltage ye-FIELD effect tube G pole, njengokunaka inani elihlukile lokumelana, futhi ngokuyisisekelo uqinisekise ukuthi I-chip yokuphatha amandla inephutha.
