Iichips ze-IC zolawulo lwamandla ikakhulu zilawula ukuguqulwa kwamandla ombane, ukuhanjiswa, ukufumanisa kunye nolunye ulawulo lwamandla kwiinkqubo zezixhobo zombane.I-semiconductor yolawulo lwamandla ukusuka kwizixhobo eziqulethwe, ugxininiso olucacileyo kulawulo lwamandla oludibeneyo lwesiphaluka (ulawulo lwamandla IC, olubizwa ngokuba yi-chip yolawulo lwamandla) isikhundla kunye nendima.I-semiconductor yolawulo lwamandla ibandakanya iinxalenye ezimbini, ezizezi, ulawulo lwamandla oludityanisiweyo lwesekethe kunye nolawulo lwamandla oludityanisiweyo lwesixhobo sesemiconductor.
Kukho iintlobo ezininzi zeesekethe ezidityanisiweyo zolawulo lwamandla, ezinokwahlulwa ngokurhabaxa kulawulo lwamandla ombane kunye neesekethe zojongano.Imodyuli ye-voltage ibandakanya i-linear low voltage drop regulator (okt i-LOD), i-positive kunye ne-negative output series circuit, ukongeza, akukho modulation yobubanzi be-pulse (PWM) uhlobo lokutshintsha isekethe, njl.
Ngenxa yenkqubela phambili yetekhnoloji, ubungakanani bomzimba wesekethe yedijithali kwitshiphu yesekethe edibeneyo iya isiba yincinci kwaye incinci, ke unikezelo lwamandla osebenzayo luphuhlisa ukuya kumbane ophantsi, kwaye uthotho lwabalawuli bombane olutsha luvela ngexesha elifanelekileyo.Isekethe yojongano lolawulo lwamandla ikakhulu ibandakanya umqhubi we-interface, umqhubi wemoto, umqhubi we-MOSFET kunye nombane ophezulu wombane/umqhubi obonisayo wangoku, njl.
Iindidi ezisibhozo eziqhelekileyo zolawulo lwamandla IC ukuhlelwa kwetshiphu
Ulawulo lwamandla izixhobo ze-semiconductor ze-discrete ziquka ezinye izixhobo ze-semiconductor zamandla emveli, ezinokuthi zohlulwe zibe ziindidi ezimbini, enye iquka i-rectifier kunye ne-thyristor;Olunye luhlobo lwe-triode, kubandakanywa i-bipolar transistor yamandla, equlethe i-MOS isakhiwo samandla entsimi ye-transistor (MOSFET) kunye ne-insulated gate bipolar transistor (IGBT).
Inxalenye ngenxa yokwanda kwee-ics zolawulo lwamandla, ii-semiconductors zamandla zabizwa ngokuba zii-semiconductors zolawulo lwamandla.Kungenxa yokuba iisekethe ezininzi ezihlanganisiweyo (IC) kwindawo yonikezelo lwamandla, abantu bangaphezulu kulawulo lwamandla ukubiza inqanaba langoku lokubonelela ngombane.
I-semiconductor yolawulo lwamandla kwindawo ehamba phambili yolawulo lwamandla e-IC, inokushwankathelwa ngoku kulandelayo 8.
1. AC/DC ukumodareyitha IC.Iqulethe isiphaluka solawulo lwe-voltage ephantsi kunye ne-high voltage switching transistor.
2. I-DC/DC yokumodareyitha IC.Kubandakanya ukunyusa / ukuhla, kunye neepompo zentlawulo.
3. ulawulo factor zamandla PFC pretuned IC.Ukubonelela ngesekethe yegalelo lamandla kunye nomsebenzi wokulungisa izinto zamandla.
4. ukumodareyithwa kwe-pulse okanye i-pulse amplitude modulation PWM/PFM control IC.I-pulse frequency modulation kunye / okanye isilawuli sokumodareyitha ububanzi be-pulse ukuze uqhube utshintsho lwangaphandle.
5. I-IC ye-linear modulation (njenge-linear low voltage regulator LDO, njl.).Kubandakanya abalawuli abaphambili kunye nabangalunganga, kunye ne-low voltage drop drop LDO modulation tubes.
6. ukutshaja ibhetri kunye nolawulo IC.Ezi ziquka ukutshaja ibhetri, ukhuseleko kunye nee-ics zokubonisa amandla, kunye nee-ics zebhetri "ezihlakaniphile" zonxibelelwano lwedatha yebhetri.
7. Ulawulo lwebhodi eshushu yokutshintsha i-IC (ikhululekile kwimpembelelo yokufaka okanye ukususa enye i-interface kwinkqubo yokusebenza).
8. MOSFET okanye IGBT switching function IC.
Phakathi kwezi ics zolawulo lwamandla, ulawulo lwamandla ombane i-ICS lolona lukhula ngokukhawuleza kwaye lunemveliso.Ii-ics zolawulo lwamandla ezahlukeneyo zinxulunyaniswa ngokubanzi nenani lezicelo ezinxulumeneyo, ngoko ke iintlobo ezininzi zezixhobo zinokudweliswa kwizicelo ezahlukeneyo.
Umkhwa wobugcisa wolawulo lwamandla kukusebenza okuphezulu, ukusetyenziswa kwamandla aphantsi kunye nobukrelekrele.Ukuphucula ukusebenza kakuhle kubandakanya imiba emibini eyahlukeneyo: kwelinye icala, ukusebenza kakuhle kokuguqulwa kwamandla kugcinwa ngelixa kunciphisa ubungakanani bezixhobo;Ngakolunye uhlangothi, ubungakanani bokukhusela abutshintshi, buphucula kakhulu ukusebenza kakuhle.
Ukuchasana nomgangatho ophantsi kwi-AC / DC ukuguqulwa kuhlangabezana nesidingo seeadaptha ezisebenza ngakumbi kunye nokubonelela ngombane kwikhompyuter kunye nezicelo zonxibelelwano.Kuyilo lwesekethe yamandla, ukusetyenziswa kwamandla okulindile ngokubanzi kuye kwancitshiswa ukuya ngaphantsi kwe-1W, kwaye ukusebenza kakuhle kwamandla kunokunyuswa ukuya ngaphezu kwe-90%.Ukunciphisa ngakumbi ukusetyenziswa kwamandla okulindileyo ngoku, ubugcisa obutsha bokwenza i-IC kunye nokuphumelela kuyilo lwesekethe yamandla aphantsi kuyafuneka.
