Itandukaniro

Itandukaniro hagati ya DC yagennye guhinduranya amashanyarazi hamwe numurongo utanga amashanyarazi kubisobanuro
Itandukaniro ryabo rinini ni umurongo ugengwa nogutanga amashanyarazi muri tube (haba bipolar cyangwa MOSFET) ikora kumurongo, mugihe amashanyarazi yo guhinduranya mumashanyarazi akora muburyo bwo guhinduranya.
1．Ibisobanuro bya DC byateganijwe guhinduranya amashanyarazi
Guhindura amashanyarazi bitanga isano no gutanga amashanyarazi kumurongo.Guhindura amashanyarazi bitangwa binyuze mumuzunguruko wumuzunguruko wo guhinduranya umuyoboro wihuta wihuta no guhagarikwa.Imbaraga za DC mumashanyarazi menshi ya AC kuri transformateur kugirango ihindurwe na voltage, bityo bitange ibisabwa cyangwa itsinda rya voltage!Kubivuga muri make, guhinduranya amashanyarazi ni transformateur.Guhindura amashanyarazi bigerwaho na: gukosora muri DC - guhindurwa mumashanyarazi asabwa (cyane cyane kugirango uhindure voltage) - hanyuma ukosorwa mumashanyarazi ya DC.

2. Igisobanuro cyo gutanga amashanyarazi kumurongo
Amashanyarazi aringaniye ni transformateur ibanza kugabanya voltage amplitude yumuyaga uhinduranya hanyuma ikayikosora ikoresheje umuzunguruko kugirango ibone amashanyarazi ataziguye.Hanyuma irayungurura kugirango ibone imbaraga za DC hamwe na voltage ntoya.Kugirango ugere kuri voltage nini ya DC, igomba kugengwa numuzunguruko wa voltage.
Icya kabiri, itandukaniro riri hagati yihame ryakazi rya DC ryagennye guhinduranya amashanyarazi no gutanga amashanyarazi kumurongo

Ihame ryakazi ryo guhindura amashanyarazi.
1. Imbaraga za AC zungururwa no gukosorwa muri DC;
2. Binyuze mu muyoboro mwinshi wa PWM (ubugari bwa pulse modulasiyo) cyangwa impiswi ya modulisiyo (PFM) igenzura imiyoboro ihinduranya, DC izongerwa kuri primaire ya transfert ihindura;
3. Icyiciro cya kabiri cyo guhindura ibintu bitera voltage yumurongo mwinshi, ikosorwa kandi ikayungururwa kumuzigo;
4. Ibisohoka bisubizwa kugenzurwa binyuze mumuzunguruko runaka kugirango ugenzure umusoro wa PWM kugirango ugere kumusaruro uhamye.

Ihame ryakazi ryo gutanga umurongo.
1.Imashanyarazi isanzwe ikubiyemo cyane cyane guhinduranya inshuro, gusohora ibyakosowe, kugenzura, kugenzura, n'ibindi ...
Amashanyarazi atangwa ni imbaraga za mbere za AC zinyuze muri voltage ya transformateur, hanyuma unyuze mu cyerekezo cyumuzunguruko ukosora kugirango ubone imbaraga za DC zidahungabana.Kugirango ugere kuri DC yumubyigano mwinshi, ibisohoka voltage bigomba guhindurwa nibitekerezo bya voltage.Ubu buhanga bwo gutanga amashanyarazi burakuze cyane kandi burashobora kugera kumurongo uhamye hamwe na rippe nkeya kandi nta nkomyi n urusaku guhinduranya amashanyarazi bifite.Nyamara, ibibi byayo ni uko bisaba transformateur nini kandi nini, ingano nuburemere bwa capacitori isabwa nayo nini cyane, kandi numuyoboro wa voltage utanga umurongo ukorera kumurongo, kuburyo hariho kugabanuka kwa voltage kumurongo. umuyoboro, mubisohoka mumashanyarazi manini akora, bikavamo gukoresha ingufu za tube yahinduwe ni nini cyane, imikorere idahwitse, ariko kandi no gushiraho icyuma kinini.Amashanyarazi ntabwo akwiranye na mudasobwa nibindi bikoresho bikenerwa, bizagenda bisimburwa buhoro buhoro no guhindura amashanyarazi.

DC yagennye guhinduranya amashanyarazi no gutanga amashanyarazi kumurongo mubiranga itandukaniro.
Ibyiza byingenzi nibibi byo guhinduranya amashanyarazi
Ibyiza: Ingano ntoya, yoroheje (ingano nuburemere bwa 20-30% gusa yumurongo wumurongo wumurongo wumurongo), gukora neza (muri rusange 60-70%, mugihe amashanyarazi atangwa ari 30-40% gusa), ubwabo barwanya kwivanga , intera nini yo gusohora voltage, modularity.
Ibibi: Bitewe numuvuduko mwinshi wa voltage ikorwa mumuzunguruko wa inverter, hari umubare munini wo kwivanga mubikoresho bikikije.Birakenewe gukingirwa neza nubutaka.

Ibiranga amashanyarazi kumurongo.
Ihungabana ryinshi, rito ripple, kwizerwa cyane, byoroshye gukora mumasoko menshi asohoka ubudahwema gutanga amashanyarazi.Ingaruka ni uko ari nini, nini, kandi ugereranije idakora neza.Ubu bwoko bwamashanyarazi yagenzuwe kandi hariho ubwoko bwinshi, uhereye kumiterere yibisohoka birashobora kugabanywa mumashanyarazi agenga amashanyarazi, kugenga amashanyarazi hamwe no gushiraho amashanyarazi, guhagarara neza mumashanyarazi ahamye, hamwe nubu (dual-stabilite) amashanyarazi.Ibisohoka agaciro birashobora kugabanwa mumashanyarazi ateganijwe gutangwa, ubwoko bwa bande ihindura ubwoko, hamwe na potentiometero bihora bihinduka byinshi.Kuva mubisohoka, ibyerekana birashobora kugabanywa muburyo bwerekana ubwoko nubwoko bwa digitale.

Itandukaniro hagati ya DC igengwa noguhindura amashanyarazi hamwe numurongo wumurongo wumurongo murwego rwo gusaba
1. Guhindura amashanyarazi yatanzwe
Guhindura amashanyarazi kumurongo wuzuye wa voltage, nta voltage itandukanye, urashobora gukoresha topologiya itandukanye kugirango ugere kubisabwa bitandukanye.Igipimo cyo guhinduranya nibisohoka ripple ntabwo biri hejuru nkibikoresho bitanga umurongo, kandi imikorere ni myinshi.Irasaba ibice byinshi bya peripheri hamwe nigiciro kinini.Umuzunguruko uragoye.Guhindura amashanyarazi ya DC agenzurwa cyane cyane kugarukira kumurongo umwe, kugarukira kumurongo umwe, igice-kiraro, gusunika-gukurura, nubwoko bwumuzingi wuzuye.Itandukaniro ryibanze hagati yaryo n'umurongo ugengwa n'amashanyarazi ni uko transformateur mumuzunguruko idakora kuri frequency ikora ahubwo ikora kilohertz mirongo kugeza kuri megahertz nyinshi.Umuyoboro w'amashanyarazi ntukorera muri zone y'umurongo, ariko mukwuzura no guhagarikwa, ni ukuvuga muburyo bwo guhinduranya;guhinduranya ubwoko bwa DC bwateganijwe gutanga amashanyarazi rero yitwa.
2. Ingano yo gukoresha umurongo utanga amashanyarazi
Amashanyarazi agengwa numurongo akoreshwa kenshi mumashanyarazi make, nka LDO ikeneye guhura nikibazo cya voltage.Igipimo cya voltage igenga igipimo na ripple nibyiza, imikorere iracyari hasi, ibikenerwa mubice bya periferiya ni bike, kandi ikiguzi ni gito.Umuzunguruko uroroshye.

Ibyerekeye Ibicuruzwa

LMR14030 ni 40 V, 3.5 Intambwe yo hasi igenzura hamwe na MOSFET yo murwego rwo hejuru.Hamwe ninjiza yagutse kuva kuri 4 V kugeza kuri 40 V, irakwiriye mubikorwa bitandukanye kuva mu nganda kugera mumodoka kugirango amashanyarazi abone isoko atagengwa.Umuyoboro utuje ni 40 µA muburyo bwo gusinzira, bukwiranye na sisitemu ikoreshwa na bateri.Ultra-hasi 1 µIcyerekezo muburyo bwo guhagarika irashobora kongera igihe cya bateri.Ingano yagutse yo guhinduranya inshuro zituma haba imikorere cyangwa ingano yibigize hanze kugirango ibe nziza.Indishyi zimbere zisobanura ko uyikoresha adafite akazi katoroshye ko gushushanya indishyi.Ibi kandi bigabanya ibice byo hanze byigikoresho.Ibisobanuro bishoboza kwinjiza byemerera koroshya kugenzura no kugenzura ingufu za sisitemu.Igikoresho kandi cyubatsemo ibintu birinda umutekano nkumuzenguruko wikurikiranya, kugabanuka kwumuriro no kuzimya bitewe no gukwirakwiza ingufu nyinshi, no kurinda ibicuruzwa birenze urugero.
