Ibikoresho bishya & umwimerere bya elegitoronike, kugurisha-gushyushya imiyoborere ICs HTSSOP-14 LM5010 LM5010MHX / NOPB Ishusho Yerekanwe

ibisobanuro bigufi:

Igenzura rya LM5010 ryamanuka ryerekana imikorere yose ikenewe kugirango ishyire mubikorwa igiciro gito, gikora neza, buck bias igenzura gutanga ibirenze 1-A umutwaro uremereye.Igenzura ryinshi rya voltage ririmo N-Umuyoboro wa Buck Hindura, kandi iraboneka mumashanyarazi yazamuye 10-pin WSON na 14-pin ya HTSSOP.Gahunda yo kugenzura hysteretique ntisaba indishyi zidasubirwaho, bivamo igisubizo cyihuse cyigihe gito, kandi cyoroshya ishyirwa mubikorwa.Imikorere yumurongo ikomeza guhorana numurongo hamwe nuburyo bwo gutandukana bitewe nubusabane butandukanye hagati yinjiza voltage na ON-time.Ikibaya kiriho ubu cyashyizwe kuri 1.25 A. Ibintu byiyongereyeho birimo: VCC munsi ya volvoltage, gufunga ubushyuhe, gutwara amarembo munsi ya volvoltage, no kugabanya imipaka ntarengwa.

Igikorwa nyamukuru

Igikorwa nyamukuru cyumubyigano wa voltage.
1. Guhindura amashanyarazi.
Iyo amashanyarazi ya gride ahindagurika ako kanya, umugenzuzi wa voltage azishyura amplitude ya voltage hamwe nigisubizo cya 10-30m, bigatuma gihagarara muri ± 2%.
2. kurinda ibikorwa byinshi.
Igenzura rya voltage hiyongereyeho ihinduka ryibanze ryimikorere ya voltage igomba no kugira uburinzi burenze urugero (hejuru ya + 10% yumusaruro w’amashanyarazi), kurinda munsi ya voltage (munsi ya -10% yumusaruro w’amashanyarazi), kurinda gutsindwa kwicyiciro , imiyoboro migufi irenga kurinda ibikorwa byibanze byo kurinda.
3. Spike pulse guhagarika (kubishaka).
Imiyoboro y'amashanyarazi rimwe na rimwe igira amplitude maremare cyane, ubugari bwa pulse ni impiswi ntoya cyane, kandi izacika muri voltage yo hasi ihangane nibikoresho bya elegitoroniki.Ibirwanya anti-surge bigize amashanyarazi yagenzuwe birashobora kugira uruhare runini muguhashya izo mpanuka zikarishye.
4. kwigunga kwa EMI ikora amashanyarazi (kubishaka).
Ibikoresho bya CNC byinshi bikosora AC / DC ikosora + PFC yumurongo wumurongo wogukosora ibintu, ubwabyo umubare munini wokwivanga icyarimwe inkomoko yo kwivanga nayo ifite ibisabwa bikomeye.Ibikoresho bitanga amashanyarazi byateganijwe birashobora gutandukanya neza imiyoboro ya interineti kubikoresho icyarimwe birashobora kandi gutandukanya neza ibikoresho byabangamiye gride.
5. kurinda inkuba (bidashoboka).
Ugomba kugira ubushobozi bwo kurinda inkuba.

Ibyiciro

Igenzura rya DC rishobora kugabanywamo ibyiciro bibiri.

1, ubwoko bwo guhinduranya
Ubwoko butandukanye bwamashanyarazi ahamye avuye kumurongo ugenzurwa numurongo wamashanyarazi nuburyo bwo guhinduranya DC yagenzuye amashanyarazi, afite ubwoko bwumuzunguruko bwikurikiranya rimwe, icyerekezo kimwe imbere, igice-kiraro, gusunika-gukurura-ikiraro cyuzuye.Itandukaniro ryibanze hagati yibi bitanga umurongo wumurongo ni uko transformateur idakorera kuri frequency ikora ahubwo kilohertz mirongo kugeza kuri megahertz nyinshi.Imikorere ya tube ntabwo ikora mukwuzura no guca ahantu aribwo buryo bwo guhinduranya;guhinduranya amashanyarazi bityo yitwa.

2, Umurongo
Umuyoboro wa voltage wumurongo ufite ikintu gihuriweho nuburyo umuyoboro wibikoresho byamashanyarazi ukora muri zone yumurongo, ushingiye kumanuka wa voltage hagati yigituba kugirango uhagarike ibisohoka.Bitewe no gutakaza igihagararo kinini cya tube igenzura, hagomba gushyirwaho icyuma kinini gishyuha kugirango kigabanye ubushyuhe.Transformator nayo iraremereye kuko ikora kuri 50Hz.

Ibyiza byubu bwoko bwamashanyarazi ni stabilite ihanitse, ripple ntoya, kwizerwa cyane, byoroshye gukora byinshi, bikomeza guhindurwa umusaruro wibicuruzwa byarangiye.Ingaruka ni uko ari nini, nini, kandi ugereranije idakora neza.Ubu bwoko bwamashanyarazi ahamye kandi hariho ubwoko bwinshi, uhereye kumiterere yibisohoka birashobora kugabanywa mumashanyarazi ya voltage ihagaze hamwe nogutanga amashanyarazi hamwe no gushiraho ingufu za voltage, guhagarara neza mumashanyarazi ahamye, hamwe nubu (byombi-bihamye ) amashanyarazi.Ibisohoka agaciro birashobora kugabanwa muburyo bugaragara-busohora amashanyarazi, bande ihinduka-ihindurwa, na potentiometero ikomeza guhindurwa ubwoko bwinshi.Kuva mubisohoka, ibyerekanwa birashobora kugabanywa muburyo bwerekana ubwoko bwubwoko bwa digitale, nibindi. 三、

Menyekanisha

DC guhinduranya amashanyarazi.
Ibyiza byo guhinduranya amashanyarazi nubunini bwazo, uburemere, umutekano, no kwizerwa.Baraboneka mumashanyarazi kuva kuri watt nkeya kugeza kuri kilowat nyinshi.Hano hari ibikoresho bike byo guhindura amashanyarazi
1. Ibikoresho by'itumanaho
Amashanyarazi y'itumanaho mubyukuri ni DC / DC ihindura ubwoko bwamashanyarazi, ariko mubisanzwe ni DC-48V cyangwa -24V itanga amashanyarazi, hamwe na bateri yinyuma kumashanyarazi ya DC, amashanyarazi ya DC mumashanyarazi yumurimo wumuzunguruko, mubisanzwe igabanijwemo amashanyarazi yo hagati, gutanga amashanyarazi, hamwe no gutanga amashanyarazi atatu, iyanyuma niyo yizewe cyane.
2. AC / DC
Ubu bwoko bw'amashanyarazi, buzwi kandi nk'amashanyarazi y'ibanze, bubona ingufu ziva mu mashanyarazi kandi bukabona ingufu za DC nyinshi binyuze mu gukosora amashanyarazi menshi no kuyungurura kugirango DC / DC ihindurwe kugirango ibone amashanyarazi ya DC imwe cyangwa menshi ahamye ku bisohoka, hamwe imbaraga kuva kuri watt nkeya kugeza kuri kilowat nyinshi.Hariho ibintu byinshi byerekana ibicuruzwa nkibi, kandi amashanyarazi y'ibanze (AC220 yinjiza, DC48V, cyangwa 24V ibisohoka) mumashanyarazi y'itumanaho nayo ni ubu bwoko, bitewe nibyo umukoresha akeneye.
3. Amashanyarazi asanzwe
Hamwe niterambere ryihuse ryubumenyi nubuhanga, kwizerwa kwamashanyarazi, hamwe nubushobozi / ingano yikigereranyo bigenda byiyongera, amashanyarazi atanga module agenda yerekana ubukuru bwayo, ikora kumurongo mwinshi, ubunini buto, kwizerwa cyane, kwishyiriraho byoroshye no guhuza kwaguka, kuburyo bwinshi kandi bukoreshwa cyane.Nubwo hari umusaruro wimbere mu gihugu, kubera ko umusaruro utigeze ufatwa nu rwego mpuzamahanga, igipimo cyo gutsindwa ni kinini.
4. Amashanyarazi
Amashanyarazi ya radiyo yinjiza AC220V / 110V, ibisohoka DC13.8V, ingufu nimbaraga za radio, amps make, hamwe na amps amagana arahari.Kugirango wirinde ingufu za AC gride kunanirwa gukora kumaradiyo, kandi ukeneye kugira ipaki ya batiri nkigisubizo, ubwo buryo bwo gutanga amashanyarazi hiyongereyeho umusaruro wa voltage ya 13.8V DC nayo ifite bateri yishyuza imikorere ihinduka.
5. DC / DC
Muri sisitemu y'itumanaho, izwi kandi nk'amashanyarazi ya kabiri, ni amashanyarazi y'ibanze cyangwa ipaki ya batiri ya DC kugirango itange ingufu za DC, nyuma yo guhindura DC / DC kuruhande rusohoka kugirango ubone ingufu za DC cyangwa amashanyarazi menshi ya DC.
Nubwo amashanyarazi ya DC / DC ahenze cyane, duhereye ku giciro rusange cyibicuruzwa bimaze igihe kirekire bisabwa, cyane cyane kubera kunanirwa na sisitemu hamwe nigiciro kinini cyo kubungabunga no gutakaza ubushake, guhitamo module yingufu. iracyahenze cyane, birakwiye kandi kuvugwa hano ni Roche ihinduranya umuzenguruko, inyungu zayo zidasanzwe nuburyo bworoshye bwumuzunguruko, gukora neza hamwe n’ibisohoka n’umuvuduko hamwe n’agaciro ka ripple hafi ya zeru.
6. Amashanyarazi adasanzwe
Umuvuduko mwinshi hamwe nu mashanyarazi make, ibikoresho bitanga amashanyarazi menshi, 400Hz yinjiza AC / DC amashanyarazi, nibindi birashobora gushyirwa mubikorwa nkibyo kandi birashobora gutoranywa ukurikije ibikenewe bidasanzwe.
