Menyekanisha
Amashanyarazi asanzwe agenga amashanyarazi atangwa binyuze mumuzunguruko wicyitegererezo kugirango ugenzure kuri / kuzimya umuyoboro wogutanga amashanyarazi kugirango uhindure imbere imbere yumuriro w'amashanyarazi kugirango voltage kumuzigo ihamye.
Guhindura voltage igenzura amashanyarazi ni ukugenzura igipimo cyumuyoboro uhinduranya no kuzimya kugirango uhindure ingufu za voltage.
Ibyiza
Ibyiza byo guhinduranya voltage igenzura amashanyarazi.
Ibyiza 1: gukoresha ingufu nke, gukora neza, guhuza no kuremerera
Inyungu zayo nini nubushobozi buhanitse.Muburyo bwo guhinduranya, tristoriste ubwayo ikoresha imikorere mike, kandi nuyobora kugenzura ubwayo irashobora kugera kuri mirongo irindwi kugeza kuri mirongo inani ku ijana, mugihe idakeneye guhinduranya intambwe.Isohora ryayo risohoka rikora kumurongo mwinshi kandi hamwe nubunini buri munsi ya 50 Hz muri IF transformateur.Umuzenguruko wo guhinduranya ibintu, kubwibyo, ufite inyungu zo kuba nto kandi zoroheje.Irashobora gukora hejuru yumurongo mugari wa voltage.
Ibyiza 2: Urwego runini rwo kugenzura voltage
Umuvuduko w'amashanyarazi uva muguhindura ibintu bigengwa ninshingano yinshingano yikimenyetso cyo kwishima, kandi impinduka zinjira mumashanyarazi zinjiza zishobora kwishyurwa no guhinduranya inshuro cyangwa kwaguka.Muri ubu buryo, mugihe habaye impinduka nini mumashanyarazi ya gride ya voltage, irashobora gukomeza kwemeza imbaraga zidasanzwe.Muri rusange, imbaraga za voltage zo guhinduranya amashanyarazi ni nini cyane kandi ningaruka zo guhagarika imbaraga ni nziza.
Inyungu ya 3: Impapuro zuzunguruka zoroshye
Kurugero, hariho kwishima nizindi-zishimishije, mugari-nini na frequency-igenzurwa, iherezo rimwe na kabiri-irangiye, nibindi.Abashinzwe gutanga amashanyarazi barashobora gukoresha ibyiza byubwoko butandukanye bwumuzunguruko kugirango bashushanye kandi batezimbere guhinduranya imbaraga za voltage zishobora guhura nibisabwa bitandukanye.
Uruhare
Kuva havumburwa amashanyarazi kugeza na nubu, korohereza amashanyarazi birashobora kuvugwa niterambere ryumuryango, ubuzima bwabantu bwazanye iterambere ryinshi kandi byoroshye.Ariko biratuzanira icyarimwe icyarimwe, ariko kandi bituzanira ibibazo byinshi.Mubikorwa byacu bizima, dukunze guhura na voltage idahungabana, cyane cyane hagati yumurongo, ndetse no mugihe cyamashanyarazi.Muri societe igenda irushaho gusobanuka neza, niba voltage idahindagurika, bizazana ingorane zikomeye mubuzima bwacu bwo gukora.Inzira imwe yonyine yo guhindura uruziga cyangwa guhindura ikibanza ni ugushiraho ibikoresho bifasha amashanyarazi.Naho kubijyanye nibikoresho bifasha ingufu, imashini zihenze kandi zoroshye ni imashini igenzura voltage.
Mu minsi ya mbere, umurimo wingenzi wumuyobozi wa voltage kwari uguhindura voltage.Umugenzuzi ashobora kuzamura voltage mugihe habaye ihindagurika rya voltage idahindagurika, cyangwa mugihe habaye voltage nkeya, kugirango ibikoresho bikore bisanzwe.Ariko, hamwe niterambere ryikoranabuhanga, kimwe nabantu basabwa cyane kubikoresho.Igenzura rya voltage yuyu munsi, ntabwo ryemeza gusa ko voltage isanzwe, ariko kandi irinda umutekano wimikorere yamashanyarazi.Kubwibyo, usibye kwemeza imikorere isanzwe yibikoresho, umugenzuzi wa voltage afite kandi kurinda imiyoboro ngufi, kurinda icyiciro gito, nibindi bikorwa byinshi byo kurinda.
Ibipimo nyamukuru
Ibipimo nyamukuru bya DC voltage igenzura.
DC yagenzuye amashanyarazi (voltage igenzura) ibipimo byingenzi bya tekiniki irashobora kugabanywamo ibyiciro bibiri: kimwe ni ibipimo byubuziranenge, byerekana ibyiza bya DC itanga ingufu zitanga amashanyarazi.Harimo ituze, irwanya imbere imbere (isohoka irwanya), imbaraga za ripple, hamwe nubushyuhe bwubushyuhe.Ikindi cyiciro nicyerekezo kiranga, kigaragaza ibiranga ibintu bitanga amashanyarazi agenzurwa na DC.Kurugero, kwinjiza DC yagenzuye amashanyarazi yumuriro, ibisohoka voltage, ibisohoka, nibisohoka voltage igenzura.
1, igipimo cyo kugenzura voltage SV
Igipimo cyumubyigano nigipimo cyingenzi kiranga imikorere ya DC voltage stabilisation itanga amashanyarazi, izwi kandi nkikintu gihamye cyangwa ibintu bihamye.Irangwa iyo kwinjiza voltage VI ihindutse mugihe DC voltage stabilisation yamashanyarazi itanga ingufu za VO ituje, mubisanzwe bigaragazwa nkijanisha ryimpinduka zijyanye no kwinjiza no gusohora voltage kuri buri gice cyumuvuduko wa voltage.
2, igipimo cyo guhindura SI
Igipimo kiriho ubu ni ikimenyetso cyingenzi cyerekana ubushobozi bwimitwaro ya DC voltage stabilisateur, izwi kandi nkibintu bihamye.Irangwa mugihe iyinjizwa ryumubyigano ridahindutse, amashanyarazi ya DC yoguhindura amashanyarazi bitewe nimpinduka zumuvuduko wumuvuduko (ibisohoka), hamwe n’imihindagurikire y’ibisohoka biturutse ku bushobozi bwo guhagarika, mu bihe by’imihindagurikire y’imitwaro yagenwe, ubusanzwe bigaragazwa nkijanisha ryimpinduka zasohotse mumashanyarazi kuri buri gice gisohoka voltage igipimo cyateganijwe cya DC voltage stabilisation itanga amashanyarazi.
3, Ikigereranyo cyo kwangwa SR
Ikigereranyo cyo kwangwa ripple cyerekana DC voltage igenzura kuruhande rwinjiza rwo kwinjiza ubushobozi bwa voltage yo kwangwa, mugihe DC yumucungamutungo winjiza nibisohoka DC voltage igenzura ibice bidahindutse, igipimo cyo kwanga ripple gikunze kugaragara mubijyanye no kwinjiza ripple. voltage peak-to-peak and output ripple voltage peak-to-peak ratio, mubisanzwe bigaragarira muri décibel, ariko rimwe na rimwe birashobora kugaragazwa nkijanisha, cyangwa muburyo butaziguye hamwe nikigereranyo cya bombi bavuze.
4, Ubushyuhe butajegajega K.
Ubushyuhe butajegajega bwamashanyarazi ya DC bwerekanwe mubushuhe bwa DC itanga ubushyuhe bwa Ti urwego ntarengwa rwimpinduka (Tmin ≤ Ti ≤ Tmax) DC itanga amashanyarazi asohora voltage ugereranije nihinduka ryijanisha.
Ibyerekeye Ibicuruzwa
LM9036 ultra-low quiescent igenzurwa nubu iragaragaza imbaraga nkeya ziva mumashanyarazi hamwe numuyoboro muke muburyo bwo guhagarara.Hamwe na munsi ya 25µA Ground Pin kuri 0.1mA umutwaro, LM9036 irakwiriye rwose kubinyabiziga hamwe nubundi buryo bukoresha bateri.LM9036 igumana ibintu byose biranga abagenzuzi bata ishuri harimo ibikoresho bito bito bya PNP, kurinda imiyoboro ngufi, kurinda bateri, no guhagarika ubushyuhe.LM9036 ifite 40V ntarengwa ntarengwa yo gukora, ntarengwa −40 ° C kugeza kuri + 125 ° C yubushyuhe bwo gukora, hamwe na ± 5% byihanganira ingufu za voltage hejuru yibisohoka byose, ingufu zinjira, hamwe nubushyuhe.
