Ama-chips e-IC okuphatha amandla ikakhulukazi aphatha ukuguqulwa kwamandla kagesi, ukusatshalaliswa, ukutholwa kanye nokunye ukuphathwa kwamandla ezinhlelweni zemishini kagesi.Isemiconductor yokuphathwa kwamandla evela kumadivayisi aqukethwe, ukugcizelelwa okucacile kwesekethe edidiyelwe yokuphathwa kwamandla (ukuphathwa kwamandla IC, okubizwa ngokuthi yi-chip management chip) isikhundla nendima.I-semiconductor yokuphathwa kwamandla ihlanganisa izingxenye ezimbili, okuyisekethe edidiyelwe yokuphathwa kwamandla kanye nedivayisi ye-discrete semiconductor yokuphathwa kwamandla.
Kunezinhlobo eziningi zamasekethe adidiyelwe okuphathwa kwamandla, angahlukaniswa cishe abe ukulawulwa kwamandla kagesi kanye namasekhethi esixhumi esibonakalayo.I-voltage modulator ihlanganisa isilawuli se-linear low voltage drop regulator (okungukuthi, i-LOD), isekethe yochungechunge lokuphumayo okuhle nokubi, ngaphezu kwalokho, ayikho i-pulse width modulation (PWM) yohlobo lokushintsha isifunda, njll.
Ngenxa yenqubekelaphambili yezobuchwepheshe, usayizi womzimba wesekhethi yedijithali ku-chip yesekethe ehlanganisiwe uya uba mncane futhi ube mncane, ngakho amandla okusebenza athuthukela ku-voltage ephansi, futhi uchungechunge lwabalawuli bamandla kagesi abasha luvela ngesikhathi esifanele.Umjikelezo wokuphathwa kwamandla ikakhulukazi uhlanganisa umshayeli wesixhumi esibonakalayo, umshayeli wemoto, umshayeli we-MOSFET kanye nomshayeli we-voltage ephezulu/phezulu wamanje wokubonisa, njll.
Izinhlobo eziyisishiyagalombili ezijwayelekile zokuphathwa kwamandla kwe-IC chip classification
Amadivayisi okuphatha amandla ahlukene e-semiconductor ahlanganisa amanye amadivaysi e-semiconductor yamandla endabuko, angahlukaniswa abe izigaba ezimbili, esisodwa sihlanganisa i-rectifier ne-thyristor;Olunye uhlobo lwe-triode, okuhlanganisa i-power bipolar transistor, equkethe i-MOS structure power field effect transistor (MOSFET) kanye ne-insulated gate bipolar transistor (IGBT).
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 (ikhululekile 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.
Umkhuba wezobuchwepheshe wokuphathwa kwamandla ukusebenza kahle okuphezulu, ukusetshenziswa kwamandla okuphansi kanye nobuhlakani.Ukuthuthukisa ukusebenza kahle kuhilela izici ezimbili ezihlukene: ngakolunye uhlangothi, ukusebenza kahle okuphelele kokuguqulwa kwamandla kugcinwa ngenkathi kunciphisa ubukhulu bemishini;Ngakolunye uhlangothi, usayizi wokuvikela awushintshile, uthuthukisa kakhulu ukusebenza kahle.
Ukumelana nesifunda okuphansi ekuguquleni kwe-AC/DC kuhlangabezana nesidingo sama-adaptha asebenza kahle kakhudlwana nezinto zikagesi ezinhlelweni zekhompuyutha nezokuxhumana.Ekwakhiweni kwesekethe yamandla, ukusetshenziswa kwamandla okulindile okujwayelekile kwehlisiwe kwaba ngaphansi kwe-1W, futhi ukusebenza kahle kwamandla kunganyuswa kube ngaphezu kwama-90%.Ukuqhubeka nokunciphisa ukusetshenziswa kwamandla okulindile kwamanje, ubuchwepheshe obusha bokukhiqiza i-IC kanye nempumelelo ekwakhiweni kwesekethe yamandla aphansi kuyadingeka.
