Isingeniso Somkhiqizo
1.Amandla kagesi azinzile.
Ukunikezwa kwamandla kagesi azinzile (i-voltage ezinzile) iyisisetshenziswa se-elekthronikhi esinganikeza amandla azinzile e-AC noma e-DC emlayishweni, okuhlanganisa ukunikezwa kwamandla kagesi azinzile e-AC kanye nokuphakelwa kwamandla kagesi azinzile kwe-DC ezigabeni ezimbili.
2. Isidingo sokusebenzisa izinto zikagesi ezilawulwayo.
Ngokuthuthuka okusheshayo komphakathi, izisetshenziswa ezisebenzisa ugesi ziyanda usuku nosuku.Kodwa-ke, ukuguga nokuthuthukiswa kokusalela kwezinsiza zokudluliswa kwamandla kanye nokusatshalaliswa kwamandla, kanye nesakhiwo esingesihle kanye nokungatholakali kwamandla okwanele kubangela ugesi womsebenzisi wokugcina ubephansi kakhulu, kuyilapho abasebenzisi bolayini bevame ukuba namandla kagesi aphezulu.Ezisetshenziswa ezisebenzisa amandla, ikakhulukazi ezobuchwepheshe obuphezulu nezinembayo ezinezidingo eziqinile zamandla kagesi, kuba sengathi aziqinisekisiwe.
Ama-voltage angazinzile angabangela ukulimala okubulalayo noma ukungasebenzi kahle kwemishini, kuthinte ukukhiqizwa, kubangele ukubambezeleka kokulethwa, ikhwalithi engazinzile, nokunye ukulahlekelwa okuningi.Ngesikhathi esifanayo, isheshisa ukuguga kwemishini, ithinta impilo yayo yesevisi, futhi ize ishise izesekeli, ukuze umnikazi abhekane nenkinga yokudinga ukulungiswa noma ukuvuselela imishini ngesikhathi esifushane, echitha izinsiza;ezimweni ezimbi kakhulu, izingozi zokuphepha zenzeke, zibangele ukulahlekelwa okungenakubalwa.
3. Ukunikezwa kukagesi okulawulwa yi-DC.
Eyaziwa nangokuthi i-DC voltage regulator.I-voltage yayo yokuhlinzeka ngokuvamile i-voltage ye-AC, lapho i-voltage ye-voltage ye-AC yokunikezela noma ukumelana nomthwalo ophumayo ishintsha, i-voltage ephumayo yomlawuli eqondile ingagcinwa izinzile.Imingcele yesilawuli sikagesi ukuzinza kwe-voltage, i-ripple coefficient, nesivinini sokuphendula.Owokuqala ubonisa umphumela woshintsho ku-voltage yokufaka ku-voltage yokuphumayo.I-ripple coefficient ibonisa usayizi wengxenye ye-AC ye-voltage ephumayo ngaphansi kwezimo zokusebenza ezilinganiselwe;lokhu kwakamuva kubonisa isikhathi esidingekayo ukuze i-voltage ibuyele enanini layo elivamile lapho i-voltage yokufaka noma umthwalo ushintsha kakhulu.I-DC voltage regulator ihlukaniswe izigaba ezimbili: i-continuous conductive kanye nohlobo lokushintsha.Eyangaphambili nge-frequency transformer eya ku-voltage ye-AC yesigaba esisodwa noma yesigaba sesithathu enanini elifanele, yabe isilungiswa, yahlungwa, ukuze kutholwe amandla e-DC angazinzile, bese kuba yisekethe yesilawuli se-voltage ukuze kutholwe i-voltage ezinzile (noma yamanje).Lolu hlobo lolayini wokuphakela amandla lulula, i-ripple incane, ukugxambukela kuncane, kodwa umthamo mkhulu, izinto ezisetshenziswayo ziningi, nokusebenza kahle kuphansi (ngokuvamile kungaphansi kuka-40% kuya ku-60%).Eyakamuva ilawula i-voltage ephumayo ngokushintsha isilinganiso sesikhathi sokuvula/sokuvala sento yokulungisa (noma ukushintsha) ukuze kuzuzwe ukulawulwa kwamandla kagesi.Lolu hlobo lokunikezwa kwamandla ludla amandla amancane futhi lusebenza kahle cishe ngama-85%.
Isicelo se-4.DC voltage regulator.
I-DC voltage regulator isetshenziswa kakhulu kwezokuvikela kuzwelonke, ucwaningo lwesayensi, amanyuvesi namakolishi, amalabhorethri, amabhizinisi ezimboni nezimayini, i-electrolysis, i-electroplating, imishini yokushaja, nokunye ukuphakelwa kukagesi we-DC.
5.Incazelo ye-LM5010A
Isilawuli sokushintshela phansi se-LM5010Ax siyinguqulo ethuthukisiwe ye-LM5010 enobubanzi bokusebenza bokufaka obunwetshwayo bufinyelele ku-6-V ubuncane.I-LM5010Ax ifaka yonke imisebenzi edingekayo ukuze kusetshenziswe isilawuli semali eshibhile, esisebenzayo, esikwazi ukuhlinzeka ngokudlula komthwalo wamanje ongu-1-A.Lesi silawuli se-high-voltage sihlanganisa i-N-Channel Buck Switch, futhi sitholakala ngamaphakeji we-HTSSOP angu-10-pin athuthukiswe ngokushisa nangu-14.Isikimu sokulawula se-ON-time esiqhubekayo asidingi isinxephezelo se-loop esiholela ekuphenduleni kwesikhashana komthwalo osheshayo kanye nokusetshenziswa kwesekethe okulula.I-frequency yokusebenza ihlala ihambisana nokuhluka komugqa nomthwalo ngenxa yobudlelwane obuphambene phakathi kwe-voltage yokufaka kanye ne-ON-time.Ukutholwa komkhawulo wamanje esigodini kusethelwe ku-1.25 A. Izici ezengeziwe zifaka: Ukukhiya kwe-VCC undervoltage, ukuvala shaqa kwe-thermal, ukuvala i-gate drive undervoltage lockout, kanye nesikhawuli somjikelezo omkhulu wokusebenza.
