Ubumenyi bwibanze bwimbaraga adapt

Imbaraga zamashanyarazi zizwi nkibikorwa byo hejuru kandi bitanga ingufu zitanga ingufu.Yerekana icyerekezo cyiterambere cyogutanga amashanyarazi yagenwe.Kugeza ubu, monolithic power adapter ihuriweho n’umuzunguruko yakoreshejwe cyane kubera ibyiza byayo byo kwishyira hamwe kwinshi, imikorere ihenze cyane, umuzenguruko woroheje wa periferique hamwe nindangagaciro nziza.Byahindutse ibicuruzwa byatoranijwe byimbaraga ziciriritse nimbaraga nke adaptateur mugushushanya.

Impinduka y'ubugari

Uburyo bwo kugenzura uburyo bukoreshwa muburyo bukoreshwa na adapt.Impinduka z'ubugari bwa pulse ni uburyo bwo kugenzura ibintu, bihindura kubogama kwa base ya transistor cyangwa irembo rya MOS ukurikije ihinduka ryumutwaro uhuye kugirango uhindure igihe cyo gutwara transistor cyangwa MOS, kugirango uhindure umusaruro wo guhinduranya amashanyarazi yagenwe.Ibiranga ni ugukomeza guhinduranya inshuro zihoraho, ni ukuvuga, guhinduranya kwinzira ntiguhinduka, no guhindura ubugari bwa pulse kugirango ugabanye impinduka ziva mumashanyarazi asohoka mumashanyarazi mugihe gride ya voltage hamwe nu mutwaro uhinduka

Igipimo cyo guhindura imitwaro

Igipimo cyumutwaro wambukiranya bivuga ihinduka ryumuvuduko wibisohoka biterwa nimpinduka yumutwaro mumiyoboro myinshi isohora ingufu adapt.Guhindura imitwaro yingufu bizatera impinduka ziva mumashanyarazi.Iyo umutwaro wiyongereye, ibisohoka bigabanuka.Ibinyuranye, iyo umutwaro ugabanutse, ibisohoka biriyongera.Impinduka zisohoka zatewe nimbaraga nziza zo guhindura ibintu ni nto, naho urutonde rusange ni 3% - 5%.Nibipimo byingenzi byo gupima imbaraga za voltage zihagarika imikorere yimiyoboro myinshi isohora ingufu adapt.

Igikorwa kibangikanye

Kugirango tunonosore ibyasohotse nibisohoka imbaraga, adaptate nyinshi zishobora gukoreshwa murwego rumwe.Mugihe kibangikanye, ibisohoka voltage ya buri adaptateur igomba kuba imwe (imbaraga zabo zisohoka zemerewe kuba zitandukanye), kandi uburyo bwo kugabana ubu (aha ni bwo buryo bwo kugabana ubu) bwakoreshejwe kugirango harebwe niba ibisohoka muri buri power adapt ikwirakwizwa ukurikije coefficient yagereranijwe.

Akayunguruzo ka Electromagnetic

Akayunguruzo ka Electromagnetic, nako kazwi nka "EMI filteri", ni ibikoresho byumuzunguruko wa elegitoronike bikoreshwa muguhagarika amashanyarazi, cyane cyane urusaku mumurongo w'amashanyarazi cyangwa kugenzura ibimenyetso.Nigikoresho cyo kuyungurura gishobora guhagarika neza urusaku rwamashanyarazi no kunoza ubushobozi bwo kurwanya kwivanga mubikoresho bya elegitoronike no kwizerwa kwa sisitemu.Akayunguruzo ka Electromagnetic ni akayunguruzo ka RF.Ku ruhande rumwe, bigomba gushungura hanze ya electromagnetic interineti ituruka kuri AC power gride;

Ku rundi ruhande, irashobora kandi kwirinda urusaku rw’ibikoresho by’ibikoresho byayo bwite, kugira ngo bitagira ingaruka ku mikorere isanzwe y’ibindi bikoresho bya elegitoronike mu bidukikije bimwe bya electroniki.Akayunguruzo ka EMI karashobora guhagarika uburyo bwombi bwo guhuza hamwe nuburyo busanzwe bwo kwivanga.Akayunguruzo ka EMI kazahuzwa na AC yinjira ya power adapt.

imirasire

Igikoresho cyo gukwirakwiza ubushyuhe gikoreshwa mu kugabanya ubushyuhe bwakazi bwibikoresho bya semiconductor, bishobora kwirinda ubushyuhe bwibanze bwa tube burenze ubushyuhe ntarengwa bwo guhuza bitewe n’ubushyuhe buke, ku buryo adapteri ishobora gukingirwa ubushyuhe bukabije.Inzira yo gukwirakwiza ubushyuhe iva mu miyoboro ya tube, isahani ntoya yo gukwirakwiza ubushyuhe (cyangwa igikonoshwa)> radiator → amaherezo ikagera mu kirere gikikije.Hariho ubwoko bwinshi bwimirasire, nkubwoko bwa plaque isanzwe, ubwoko bwanditseho (PCB), ubwoko bwimbavu, ubwoko bwimibonano mpuzabitsina nibindi.Imirasire igomba kubikwa kure yubushyuhe nka transformateur yumurongo wamashanyarazi hamwe numuyoboro wamashanyarazi bishoboka.

Umutwaro wa elegitoroniki

Icyitegererezo cyingirakamaro kijyanye nigikoresho cya elegitoronike gikoreshwa cyane nkumutwaro usohoka.Umutwaro wa elegitoronike urashobora guhindurwa muburyo bugenzurwa na mudasobwa.Umutwaro wa elegitoronike ni igikoresho gikoresha ingufu z'amashanyarazi mugucunga ingufu zimbere (MOSFET) cyangwa flux flux (cycle cycle) ya tristoriste kandi wishingikirije kumashanyarazi yatakaye.

imbaraga

Imbaraga zingirakamaro zijyanye numutwaro wumuzunguruko.Yerekana igipimo cyimbaraga zikora nimbaraga zigaragara.

imbaraga zo gukosora

PFC muri make.Igisobanuro cyingufu zikosora tekinoroji ni: imbaraga zingufu (PF) ni igipimo cyimbaraga zikora P nimbaraga zigaragara s.Igikorwa cyayo nugukomeza kwinjiza AC mubyiciro hamwe na AC yinjiza voltage, kuyungurura ibintu bihuye, no kongera imbaraga zibikoresho kugeza kubiciro byateganijwe hafi ya 1

Gukosora ibintu byoroshye

Gukosora ibintu bya pasiporo byitwa PPFC (bizwi kandi nka pasifike PFC).Ikoresha pasive yibice byinduction kugirango imbaraga zikosorwe.Umuzunguruko wacyo uroroshye kandi uhendutse, ariko biroroshye kubyara urusaku kandi birashobora kongera ingufu zingana na 80%.Ibyingenzi} ibyiza byo gukosora ibintu byoroshye ni: ubworoherane, igiciro gito, kwiringirwa na EMI nto.Ibibi ni: ingano nini nuburemere, biragoye kubona ibintu byinshi byingufu, kandi imikorere yakazi ijyanye numurongo, umutwaro ninjiza voltage

Gukora ibintu bifatika

Gukora ibintu bifatika bikosorwa byitwa APFC (bizwi kandi nka PFC ikora).Gukora ibintu bifatika bikosora bisobanura kongera imbaraga zinjiza binyuze mumuzunguruko ukora (umuzenguruko ukora), no kugenzura igikoresho cyo guhinduranya kugirango ibyinjira byinjira bikurikire ibyinjira byinjira mumashanyarazi.Ugereranije na pasiporo yingufu zo gukosora inzitizi (passive circuit), kongeramo inductance na capacitance biragoye, kandi kunoza ibintu byamashanyarazi nibyiza, ariko ikiguzi ni kinini kandi kwizerwa bizagabanuka.Umuzunguruko w'amashanyarazi wongewemo hagati yikiraro cyinjiza ikosora hamwe nisohoka rya filteri ya capacitor kugirango ikosore ibyinjira mumurongo wa sine hamwe nicyiciro kimwe na voltage yinjira kandi nta kugoreka, kandi imbaraga zishobora kugera kuri 0.90 ~ 0.99.
