I-adaptha yamandla yaziwa njengomgangatho ophezulu kunye nokubonelela ngombane okonga. Imele isikhokelo sophuhliso lonikezelo lwamandla olulawulwayo. Okwangoku, i-adapter yamandla edibeneyo ye-monolithic isekethe edibeneyo isetyenziswe ngokubanzi ngenxa yeenzuzo zayo ezibalulekileyo zokudityaniswa okuphezulu, ukusebenza kweendleko eziphezulu, isekethe ye-peripheral elula kunye nesalathisi sokusebenza kakuhle. Iye yaba yimveliso ekhethiweyo yeadaptha yamandla aphakathi kunye naphantsi-amandla kuyilo.
Ukumodareyitha kobubanzi be-Pulse
Imo yokulawula ukumodareyitha edla ngokusetyenziswa kwiadaptha yamandla. Ukumodareyitha kobubanzi be-Pulse yimowudi yokulawula i-analog, ehlengahlengisa i-bias yesiseko se-transistor okanye isango le-MOS ngokutshintsha komthwalo ohambelanayo ukutshintsha ixesha lokuqhuba le-transistor okanye i-MOS, ukuze utshintshe imveliso yokutshintsha umbane olawulwayo. Uphawu lwayo kukugcina i-frequency yokutshintsha rhoqo, oko kukuthi, umjikelo wokutshintsha uhlala ungatshintshi, kwaye utshintshe ububanzi be-pulse ukunciphisa utshintsho lombane ophumayo we-adapter yamandla xa i-voltage yegridi kunye nokutshintsha komthwalo.
Izinga lohlengahlengiso lomthwalo onqamlezayo
Izinga lokulawulwa komthwalo onqamlezayo libhekiselele kwireyithi yokutshintsha kombane ophumayo obangelwa kukutshintsha komthwalo kwi-adaptha yamandla ephuma kwiichaneli ezininzi. Ukutshintsha komthwalo wamandla kuya kubangela utshintsho lwemveliso yamandla. Xa umthwalo ukhula, imveliso iyancipha. Ngokuchasene noko, xa umthwalo uyancipha, imveliso iyanda. Utshintsho lwemveliso olubangelwa utshintsho oluhle lomthwalo wamandla luncinci, kwaye isalathisi esiqhelekileyo si-3% - 5%. Sisalathiso esibalulekileyo sokulinganisa ukusebenza kombane wokuzinzisa kweadaptha yamandla ephuma kwiitshaneli ezininzi.
Ukusebenza okufanayo
Ukuze kuphuculwe imveliso yangoku kunye namandla aphumayo, iiadaptha zamandla ezininzi zingasetyenziswa ngokufanayo. Ngexesha lokusebenza okufanayo, i-voltage ephumayo ye-adapter yamandla nganye kufuneka ifane (amandla abo aphumayo avunyelwe ukuba ahluke), kwaye indlela yokwabelana yangoku (emva koku kubhekiselwa kuyo njengendlela yokwabelana ngoku) yamkelwe ukuze kuqinisekiswe ukuba imveliso yangoku yesinye. iadaptha yamandla isasazwa ngokwe-coefficient yomlinganiselo ochaziweyo.
Isihluzi sokuphazamiseka kombane
Isihluzi sokuphazamiseka kwe-Electromagnetic, ekwabizwa ngokuba "yi-EMI filter", sisixhobo sesekethe ye-elektroniki esisetyenziselwa ukucinezela uphazamiseko lombane, ngakumbi ingxolo kwintambo yombane okanye kwilayini yesiginali yokulawula. Sisixhobo sokucoca esinokuthi sicinezele ngokufanelekileyo ingxolo yegridi yamandla kunye nokuphucula amandla okuthintela ukuphazamiseka kwezixhobo zombane kunye nokuthembeka kwenkqubo. Isihluzi sokuphazamiseka kwe-electromagnetic sesesihluzo se-RF esiphindwe kabini. Kwelinye icala, kufuneka kuhluzwe uphazamiseko lwangaphandle lwe-electromagnetic oluziswe kwigridi yamandla e-AC;
Kwelinye icala, inokunqanda ukuphazamiseka kwengxolo yangaphandle yesixhobo sayo, ukuze ingachaphazeli ukusebenza okuqhelekileyo kwezinye izixhobo zombane kwindawo efanayo ye-electromagnetic. Isihluzi se-EMI sinokucinezela zombini uphazamiseko lwemowudi yoluhlu kunye nokuphazamiseka kwemowudi eqhelekileyo. Isihluzo se-EMI siya kudityaniswa kwisiphelo se-AC engenayo ye-adaptha yamandla.
irediyetha
Isixhobo sokutshatyalaliswa kobushushu esisetyenziselwa ukunciphisa ubushushu obusebenzayo bezixhobo ze-semiconductor, ezinokuthintela ukushisa kwe-tube core ngaphezu kweqondo lokushisa eliphezulu le-junction ngenxa yokutshatyalaliswa kokushisa okungahambi kakuhle, ukwenzela ukuba i-adapter yamandla inokukhuselwa ekugqithiseni. Indlela yokutshatyalaliswa kobushushu ivela kwi-tube core, ipleyiti encinci yokuchitha ukushisa (okanye igobolondo lombhobho) > i-radiator → ekugqibeleni ukuya emoyeni ojikelezayo. Zininzi iindidi zeeradiyetha, ezifana nodidi lwepleyiti ecaba, uhlobo lwebhodi eprintiweyo (PCB), uhlobo lwembambo, uhlobo lwe-interdigital njalo njalo. Iradiyetha iya kugcinwa kude nemithombo yobushushu efana nesiguquli samaxesha ombane kunye netyhubhu yokutshintsha amandla kangangoko kunokwenzeka.
Umthwalo we-elektroniki
Imodeli esetyenziswayo inxulumene nesixhobo sombane esisetyenziswa ngokukodwa njengomthwalo wokuphuma kwamandla. Umthwalo we-elektroniki unokuhlengahlengiswa ngamandla phantsi kolawulo lwekhompyuter. Umthwalo we-elektroniki sisixhobo esisebenzisa amandla ombane ngokulawula amandla angaphakathi (MOSFET) okanye i-conduction flux (umjikelezo womsebenzi) we-transistor kunye nokuxhomekeka kumandla achithwayo kwi-tube yamandla.
amandla factor
Into yamandla inxulumene nomthwalo wendalo yesekethe. Imele umlinganiselo wamandla asebenzayo kumandla abonakalayo.
ukulungiswa kwamandla
PFC ngokufutshane. Inkcazo yeteknoloji yokulungiswa kwezinto zamandla yile: factor factor (PF) ngumlinganiselo wamandla asebenzayo P ukuya kumandla abonakalayo s. Umsebenzi wayo kukugcina igalelo le-AC langoku kwisigaba nge-voltage yegalelo le-AC, ukuhluza ii-harmonics zangoku, kunye nokunyusa amandla esixhobo kwixabiso elimiselweyo kufutshane ne-1.
Ulungiso lwamandla angenakwenziwa
Ulungiso lwamandla angenakwenziwa lubizwa ngokuba yiPPFC (ekwabizwa ngokuba yi-PFC yokwenziwa). Isebenzisa i-passive component inductance ukulungisa amandla. Isekethe yayo ilula kwaye inexabiso eliphantsi, kodwa kulula ukuvelisa ingxolo kwaye inokunyusa kuphela amandla ombane malunga nama-80%. Ezona zinto ziphambili} iingenelo zolungiso lwamandla okwenziwayo zezi: ukulula, ixabiso eliphantsi, ukuthembeka kunye ne-EMI encinci. Izinto ezingeloncedo zezi: ubungakanani obukhulu kunye nobunzima, kunzima ukufumana amandla aphezulu, kwaye ukusebenza kokusebenza kuhambelana nokuphindaphinda, umthwalo kunye negalelo lombane.
Ulungiso lwamandla asebenzayo
Ulungiso lwamandla asebenzayo lubizwa ngokuba yi-APFC (ekwabizwa ngokuba yi-PFC esebenzayo). Ulungiso lwamandla asebenzayo lubhekisa ekwandiseni igalelo lamandla ngesekethe esebenzayo (isekethe esebenzayo), kunye nokulawula isixhobo sokutshintsha ukwenza igalelo langoku lamaza ombane lilandele igalelo lamaza ombane. Xa kuthelekiswa ne-passive power factor correction circuit (i-passive circuit), ukongeza i-inductance kunye ne-capacitance inzima kakhulu, kwaye ukuphuculwa kwezinto zamandla kungcono, kodwa ixabiso liphezulu kwaye ukuthembeka kuya kuncitshiswa. Isekethe yokuguqula amandla yongezwa phakathi kwebhulorho yokulungisa igalelo kunye nemveliso yokucoca i-capacitor ukulungisa igalelo langoku kwi-sine wave kunye nesigaba esifanayo ne-voltage yegalelo kwaye akukho kuphazamiseka, kwaye into yamandla inokufikelela kwi-0.90 ~ 0.99.
