Itandukaniro
A. Ni irihe tandukaniro riri hagati yubushakashatsi bwa voltage na booster?
Igenzura rya voltage na bosters, mubisanzwe, kugenzura voltage na boosters ntaho bitandukaniye cyane, hamwe na voltage igenzura na bosters mumikorere no gukoresha, kugenzura voltage na booster bifite itandukaniro rinini.
Igenzura rya voltage rikoreshwa cyane cyane mukudahungabana kwa voltage, kandi ihindagurika rya voltage ni nini cyane, ihindagurika ryumubyigano ntirishobora kuzuza imikoreshereze isanzwe y’ibikoresho by’amashanyarazi, hamwe n’umugenzuzi wa voltage, ni ihindagurika ry’ibinini, ihindagurika ry’umubyigano, ihindagurika rya voltage muri a indangagaciro zimwe, kugirango tumenye neza ko ibikoresho byamashanyarazi bishobora gukora bisanzwe.
Igenzura rya voltage mugikorwa cyo gukora, hazaba voltage nkeya kimwe na voltage nyinshi cyane, mugihe voltage iba mike cyane, umugenzuzi wa voltage uzaba hejuru yumurongo wa voltage wongera akazi, mugihe voltage ari ndende cyane, voltage umugenzuzi ni voltage kumurimo wamafaranga.Kugirango umenye neza ko voltage yoroshye.Igenzura rya voltage rero rishobora kuzamurwa, rishobora no kuba amafaranga.
Boosters, duhereye ku izina dushobora kubona ikoreshwa ryibicuruzwa, ni ukuvuga voltage yo kuzamura ibikoresho, kandi ibi bikoresho bitanga akazi kongerera ingufu gusa.Kandi ni ugutanga agaciro keza kongerewe imbaraga, nka booster yo kuzamura agaciro ni 100V, mugihe voltage kuva 300V ikagera kuri 400V, voltage isohoka ya booster nayo izaba kuva kuri 400V kugeza 500V, kuzamura mugukoresha inzira, irashobora kuzamura gusa voltage, ariko ntishobora guhagarika voltage, bityo booster ikoreshwa mubisanzwe ahantu voltage ihagaze neza.Niba mubidukikije byimihindagurikire ya voltage, ibisohoka na voltage nayo ihindagurika.
Mubyukuri, boosters na voltage igenzura kugereranya, kubera ko imikorere yabiri idashobora, imikoreshereze ntabwo ikoreshwa, kubwibyo byombi ntibishobora kugereranya, kandi ntibishobora guca urubanza ninde mwiza ninde mubi, bigomba gucirwa urubanza kubera ibidukikije.Gukoresha ibikoresho byiza birashobora kugira uruhare, niba gukoresha nabi, noneho ibikoresho ntibikora.
Nubwo byombi bidashobora kugaragara ko ari byiza cyangwa bibi, niba tutazi neza niba dukoresha booster cyangwa voltage igenzura, niba dufite amafaranga ahagije yingengo yimari, dushobora guhitamo byimazeyo umuyobozi wa voltage.Ibi ni ukubera ko umugenzuzi wa voltage akwiranye neza nibisabwa na booster hamwe nimiterere yumurimo wa booster, mubijyanye nimikoreshereze n'imikorere.Bitewe nibidukikije bitandukanye nibikoreshwa, kugenzura no kuzamura ntibishobora kugereranywa, ntidushobora rero kuvuga uwaba mwiza ninde mubi.
B.Bisobanura iki mugukosora icyarimwe?Ni irihe tandukaniro riri hagati yo guhuza no kudahuza?
Ubusanzwe gukosora ni ugukoresha diode imwe iranga umuyobozi wa diode kugirango ikosore ibigezweho, inzira yo gukosora ntabwo isaba kugenzura abantu.Kuberako ikigezweho imbere, guca inyuma, ariko kubera ko diode ubwayo izaba ifite amashanyarazi binyuze mumashanyarazi ya voltage, inzira yo gukosora izabura ingufu, bivamo ubushyuhe, kandi imbaraga zo guhindura ingufu muriki cyiciro cyo gukosora zizakurwaho.
Gukosora guhuza bisobanura ko aho gukoresha diode mugice cyo gukosora, hakoreshwa MOS aho.Kuberako MOS ikora hamwe no kurwanya bike cyane, kubyara ubushyuhe ningufu nkeya ziratakara, bityo imbaraga zo guhindura imbaraga zikiyongera.Gahunda yo gukosora ikomatanya nuburyo buryo bwo kohereza ingufu kuva kuruhande rwambere kugeza kuruhande rwa kabiri bisabwa, umuyoboro wa MOS uhuye kuruhande rwa kabiri urakingura kandi bigatuma amashanyarazi anyuramo.Ibinyuranye, iyo ihererekanyabubasha ridakenewe, umuyoboro wa MOS urazimya, ukabuza umuyaga gutemba.
Kugira ngo tubyerekane, mugusubira inyuma, mugihe umuyoboro wingenzi wo guhinduranya uzimye, umuyoboro wa rectifier MOS umuyoboro wa kabiri urafungura, bigatuma amashanyarazi atemba.Iyo imiyoboro nyamukuru yo guhinduranya ifunguye, ikosora ikosora MOS irazimya kugirango ihagarike umuyaga unyuramo kandi transformateur ibika ingufu.Muburyo bwo kurangiza, birakenewe kugenzura ibihe no hanze yibice byombi MOS, guhinduranya ukabifunga kugirango ube ikosora ikosora, bityo byitwa gukosora.Inzira iragoye ugereranije no gukosora diode.
Ibyerekeye Ibicuruzwa
LM25118-Q1 yagutse ya voltage yagutse Buck-Boost ihindura igenzura igenzura imikorere yose ikenewe kugirango dushyire mubikorwa imikorere ihanitse, ihendutse cyane Buck-Boost igenzura ikoresheje byibuze ibice byo hanze.Buck-Boost topologiya ikomeza ibyasohotse mumashanyarazi mugihe iyinjizwa ryumubyigano ari munsi cyangwa irenze iyisohoka ryumubyigano bigatuma bikwiranye cyane nibisabwa mumodoka.LM25118 ikora nkigenzura ryamafaranga mugihe iyinjizwa ryumubyigano rirenze bihagije kurenza ibisohoka byateganijwe kandi bigenda bihinduka muburyo bwo kuzamura amafaranga nkuko voltage yinjira yegera ibisohoka.Ubu buryo bubiri bwuburyo bukomeza amabwiriza kumurongo mugari winjiza voltage hamwe nuburyo bwiza bwo guhindura muburyo bwa buck hamwe nibisohoka bidafite glitch mugihe cyinzibacyuho.Ibi byoroshye-gukoresha-kugenzura birimo abashoferi kumpande ndende ya MOSFET hamwe no kuzamura uruhande rwo hasi MOSFET.Uburyo bwo kugenzura ibiyobora bushingiye kuburyo bugezweho ukoresheje icyerekezo cyigana.Kwigana uburyo bugezweho bugabanya urusaku rwimisemburo ya pulse-ubugari bwa modulasi yumuzunguruko, bigatuma igenzura ryizewe ryinshingano ntoya cyane ikenewe mugukoresha amashanyarazi menshi.Ibindi bintu birinda kurinda birimo imipaka igezweho, guhagarika ubushyuhe, hamwe no kwinjiza ibintu.Igikoresho kiraboneka mumashanyarazi yongerewe imbaraga, 20-pin ya HTSSOP igaragaramo ipaki yerekana ifasha kugirango ifashe ubushyuhe.
