I-chip yolawulo lwamandla i-IC liziko lonikezelo lwamandla kunye nekhonkco yazo zonke iimveliso zombane kunye nezixhobo, ezinoxanduva lokuguqulwa, ukuhanjiswa, ukufumanisa kunye neminye imisebenzi yolawulo lwamandla afunekayo, sisixhobo esibalulekileyo esiyimfuneko kwiimveliso zombane kunye nezixhobo.Kwangaxeshanye, ngophuhliso lwe-Intanethi yeZinto, amandla amatsha, ubukrelekrele bokwenziwa, iirobhothi kunye nezinye iindawo ezisakhulayo zezicelo, imarike esezantsi yolawulo lweetshiphu zolawulo ingenise amathuba amatsha ophuhliso.Oku kulandelayo kukwazisa ulwahlulo, ukusetyenziswa kunye nesigwebo solawulo lwamandla izakhono ezinxulumene netshiphu ye-IC.
Ukuhlelwa kwetshiphu yolawulo lwamandla
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 modulation yomgca (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. I-IC yokulawula ibhodi eshushu yokutshintsha (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.
Eyesibini, ukusetyenziswa kwetshiphu yolawulo lwamandla
Umda wolawulo lwamandla ubanzi, kubandakanywa hayi kuphela uguqulo lwamandla oluzimeleyo (ikakhulu i-DC ukuya kwi-DC, oko kukuthi i-DC/DC), unikezelo lwamandla oluzimeleyo kunye nobhaqo, kodwa kunye nokuguqulwa kwamandla adityanisiweyo kunye nenkqubo yolawulo lwamandla.Ngokuhambelanayo, ulwahlulo lwe-chip yolawulo lwamandla lubandakanya ezi zinto, ezifana ne-linear power chip, i-chip yereferensi yombane, i-chip yamandla yokutshintsha, i-chip ye-LCD yomqhubi, i-chip yomqhubi we-LED, i-chip yokubona umbane, i-chip yokulawula ukutshaja ibhetri njalo njalo.
Ukuba uyilo lwesekethe yonikezelo lwamandla ngengxolo ephezulu kunye nokucinezelwa kwe-ripple, wacela ukuba athathe indawo encinci ye-PCB (umzekelo, iifowuni eziphathwayo kunye nezinye iimveliso zombane eziphathwayo), isiphaluka sombane asivumelekanga ukusebenzisa i-inductor (ezifana nefowuni ephathekayo) , ukulinganisa okwexeshana kunye nokuphuma kwamandla ombuso kufuneka kube ngumsebenzi wokuzijonga, ukuhla koxinzelelo olufunekayo kwi-voltage stabilizer kunye nokusetyenziswa kwayo okuphantsi kwamandla, umgca weendleko eziphantsi kunye nesisombululo esilula, Emva koko unikezelo lwamandla oluchanekileyo lukhetho olufanelekileyo.Olu nikezelo lwamandla lubandakanya obu buchwepheshe bulandelayo: ireferensi yombane echanekileyo, ukusebenza okuphezulu, iamplifier yokusebenza kwengxolo ephantsi, isilawuli sokuhla kwamandla ombane aphantsi, i-static current esezantsi.
Ukongeza kwi-chip yokuguqula amandla asisiseko, i-chip yokulawula amandla ikwabandakanya i-chip yokulawula amandla ngenjongo yokusetyenziswa kwamandla okunengqiqo.Okufana ne-NiH ibhetri ehlakaniphile yokutshaja ngokukhawuleza i-chip, i-lithium ion ibhetri yentlawulo kunye ne-chip yokulawula ukukhupha, ibhetri ye-lithium ion phezu kwe-voltage, ngaphezulu kwangoku, phezu kobushushu, i-chip yokukhusela isiphaluka esifutshane;Kumgca wonikezelo lwamandla kunye ne-backup ye-battery switching management chip, i-chip yokulawula amandla e-USB;Impompo yokutshaja, unikezelo lwamandla ombane amaninzi e-LDO, ulawulo lokulandelelana kwamandla, ukukhuselwa okuninzi, intlawulo yebhetri kunye nolawulo lokukhutshwa kwe-chip eyinkimbinkimbi yamandla, njl.
Ngokukodwa kwii-elektroniki zabathengi.Umzekelo, iDVD ephathekayo, ifowuni ephathwayo, ikhamera yedijithali njalo njalo, phantse nge 1-2 iziqwenga zolawulo lwamandla chip inokubonelela ezintsonkothileyo unikezelo lwamandla multi-umbane, ukuze ukusebenza kwenkqubo ukuya best.
Eyesithathu, i-motherboard yolawulo lwamandla chip izakhono ezilungileyo okanye ezimbi zokugweba
I-Motherboard power management chip ibaluleke kakhulu kwi-motherboard, siyazi ukuba icandelo lomsebenzi ukuhlangabezana nale meko, enye i-voltage, enye inamandla.Itshiphu yolawulo lwamandla ebhodi yomama inoxanduva lombane kwindawo nganye yetshiphu yebhodi yomama.Xa i-motherboard embi ibekwe phambi kwethu, sinokubona kuqala i-chip yolawulo lwamandla ebhodi ye-motherboard kwaye sibone ukuba i-chip ine-voltage ephumayo.
1) Okokuqala emva kokuba i-chip yokulawula amandla ebhodi enkulu yaphukile, i-CPU ayiyi kusebenza, oko kukuthi, akuyi kubakho ukushisa emva kokuba i-mainboard inikwe amandla kwi-CPU, ngeli xesha ungasebenzisa impompo ye-diode yemitha. ukuvavanya ukuchasana kwekhoyili ye-inductor kunye nomhlaba ukuba imitha yehla ixabiso lokumelana liphakama ukubonisa ukuba i-chip yokulawula amandla ilungile, ngokuchaseneyo, kukho ingxaki.
2) Ukuba i-peripheral power supply iyinto eqhelekileyo kodwa i-voltage ye-chip yolawulo lwamandla ayiqhelekanga, unokujonga kuqala umbane we-FIELD effect ityhubhu ye-G pole, njengokunikela ingqalelo kwixabiso elahlukileyo lokumelana, kwaye uqinisekise ngokusisiseko ukuba itshiphu yolawulo lwamandla inempazamo.
