Ngenisa
Ukunikezwa kwamandla okulawulwa kwamandla kagesi okujwayelekile kungomjikelezo wesampula ukuze kulawulwe ukuvula/ukuvalwa kweshubhu yesilawuli sokuphakelwa kwamandla ukuze kushintshwe ukumelana kwangaphakathi kokuphakelwa kukagesi ukuze i-voltage emthwalweni izinze.
Ukushintsha ukunikezwa kwamandla kwesilawuli sikagesi kungokulawulwa kwengxenye yeshubhu yokushintsha nokuvala ukuze kulungiswe i-voltage ephumayo.
Izinzuzo
Izinzuzo zokushintsha ugesi wesilawuli se-voltage.
Izinzuzo 1: ukusetshenziswa kwamandla okuphansi, ukusebenza kahle okuphezulu, ukubumbana nokungasindi
Inzuzo yayo enkulu ukusebenza kahle okuphezulu.Esimweni sokushintsha, i-transistor ngokwayo idla umsebenzi omncane, futhi isilawuli esishintshayo ngokwaso singafinyelela ukusebenza kahle kwamaphesenti angamashumi ayisikhombisa kuya kwamashumi ayisishiyagalombili, kuyilapho kungadingi i-transformer yokuya phansi.I-transformer yayo ephumayo isebenza kumafrikhwensi aphezulu futhi inevolumu engaphansi kuka-50 Hz kusiguquli se-IF.Ngakho-ke, umjikelezo wesilawuli sokushintsha, unenzuzo eyengeziwe yokuba yincane futhi ilula.Ingasebenza ebangeni elibanzi lamandla kagesi.
Inzuzo 2: Uhlu olubanzi lokulawulwa kwamandla kagesi
I-voltage ephuma kusilawuli esishintshayo ilawulwa umjikelezo womsebenzi wesignali evusa amadlingozi, futhi izinguquko ku-voltage yesignali yokufaka zinganxeshezelwa ngokushintshwa kwemvamisa noma ukunwetshwa.Ngale ndlela, uma kwenzeka izinguquko ezinkulu ku-voltage yegridi yefrikhwensi, isengakwazi ukuqinisekisa i-voltage ephumayo ezinzile.Sekukonke, ububanzi bamandla kagesi okushintshashintshayo bubanzi kakhulu futhi umphumela wokusimamisa i-voltage muhle uma kuqhathaniswa.
Inzuzo 3: Amafomu esekethe aguquguqukayo
Ngokwesibonelo, kukhona self-excited kanye nezinye-excited, ububanzi ububanzi futhi frequency-regulated, single-end and double-end, njalonjalo.Abathuthukisi bokuphakelwa kwamandla bangasebenzisa izinzuzo zezinhlobo ezahlukahlukene zamasekhethi ukuze baklame futhi bathuthukise izilawuli zokushintsha amandla kagesi ezingahlangabezana nezinhlelo zokusebenza ezahlukene.
Iqhaza
Kusukela ekusungulweni kukagesi kuze kube namuhla, ukunethezeka kukagesi kungathiwa ngokuthuthuka komphakathi, izimpilo zabantu zilethe inqubekelaphambili enkulu kanye nokulula.Kodwa kusilethela ukunethezeka ngesikhathi esifanayo, kodwa futhi kusilethela izinkinga eziningi.Ekukhiqizeni kwethu bukhoma, sivame ukuhlangana nokungaqini kwamandla kagesi, ikakhulukazi phakathi nomugqa, kanye nangesikhathi esiphezulu sikagesi.Emphakathini owandayo onokunemba okuphezulu, uma i-voltage ingazinzile, izoletha ukuphazamiseka okukhulu empilweni yethu yokukhiqiza.Okuwukuphela kwendlela yokushintsha isekethe noma ukushintsha indawo ukusetha ithuluzi eliwusizo likagesi.Futhi mayelana nezinto ezisiza amandla, imishini ebiza kancane futhi elula kakhulu isilawuli samandla kagesi.
Ezinsukwini zokuqala, umsebenzi oyinhloko wesilawuli se-voltage kwakuwukusimamisa i-voltage.Isilawuli singakwazi ukuphakamisa amandla kagesi uma kwenzeka ukushintshashintsha kwamandla kagesi okungazinzile, noma uma kwenzeka kuba nogesi ophansi, ukuze kuqinisekiswe ukuthi okokusebenza kungasebenza ngendlela evamile.Nokho, ngokuthuthukiswa kobuchwepheshe, kanye nezidingo zabantu ngokuya okusezingeni eliphezulu imishini.Izilawuli ze-voltage zanamuhla, aziqinisekisi kuphela ukuthi i-voltage ijwayelekile, kodwa futhi iqinisekisa ukuphepha kokusebenza kukagesi.Ngakho-ke, ngaphezu kokuqinisekisa ukusebenza okujwayelekile kwemishini, isilawuli sikagesi sinokuvikelwa kwesekethe emfushane, ukuvikela kwesigaba esifushane, neminye imisebenzi eminingi yokuvikela.
Amapharamitha amakhulu
Imingcele eyinhloko ye-DC voltage regulator.
Ukunikezwa kwamandla kagesi alawulwa yi-DC (isilawuli se-voltage) semingcele yobuchwepheshe eyinhloko ingahlukaniswa ngezigaba ezimbili: eyodwa izinkomba zekhwalithi, ezibonisa ukufaneleka kokuphakelwa kwamandla kagesi we-DC.Kuhlanganisa ukuzinza, ukumelana kwangaphakathi okulingana (ukumelana nomphumela), i-ripple voltage, kanye ne-coefficient yezinga lokushisa.Esinye isigaba inkomba yesici, ebonisa izici ezingokwemvelo zokuphakelwa kukagesi okulawulwa yi-DC.Isibonelo, okokufaka kwe-DC elawula amandla kagesi kagesi, i-voltage ephumayo, yamanje ephumayo, kanye nobubanzi bokulawulwa kwamandla kagesi okukhiphayo.
1, i-voltage regulation rate SV
Izinga lokulawulwa kwamandla kagesi liyinkomba ebalulekile ekhombisa ukusebenza kwamandla kagesi wokusimamisa kagesi we-DC, okwaziwa nangokuthi yisici sokuzinza noma isici sokuzinza.Ibonakala lapho i-voltage VI yokufaka ishintsha lapho ukuqina kwamandla kagesi we-DC okukhipha amandla kagesi we-VO ukuzinza, ngokuvamile kuvezwa njengephesenti loshintsho oluhlobene ku-voltage yokufaka neyokukhiphayo ngeyunithi ngayinye ye-voltage ephumayo.
2, isilinganiso samanje sokulungiswa kwe-SI
Izinga lokulawula lamanje liyinkomba enkulu yomthamo womthwalo we-DC voltage stabilizer, eyaziwa nangokuthi isici samanje sokuzinza.Ibonakala lapho i-voltage yokufaka ihlala ingashintshile, amandla kagesi wokusimamisa i-DC ngenxa yezinguquko kumthwalo wamanje (ophumayo wamanje), kanye nokuguquguquka kwamandla kagesi okukhiphayo okubangelwa amandla okucindezela, ngaphansi kwemibandela yoshintsho olushiwo lomthwalo wamanje, ngokuvamile ovezwayo. njengephesenti loshintsho ku-voltage ephumayo ngeyunithi ngayinye izinga lokulawulwa kwamandla kagesi okukhipha amandla we-DC voltage stabilization power supply.
3,Rpple rejection ratio SR
Isilinganiso sokwenqatshwa kwe-ripple sibonisa isilawuli sikagesi se-DC esohlangothini lokokufaka kokwethulwa kwamandla kagesi amakhulu, lapho okokufaka nokukhishwayo kwezingxenye zokulawula kagesi ka-DC we-DC zihlala zingashintshile, isilinganiso sokwaliwa kwe-ripple sivamise ukuvezwa ngokuya ngokufaka kwe-ripple. I-voltage peak-to-peak kanye ne-ripple voltage peak-to-peak ratio, ngokuvamile evezwa ngama-decibel, kodwa ngezinye izikhathi ingavezwa njengephesenti, noma ngokuqondile nesilinganiso salokhu kokubili okushiwo.
4, Ukuqina kwezinga lokushisa K
Ukuzinza kwezinga lokushisa komthombo wamandla kagesi we-DC ohlanganisiwe kucaciswe ekusetshenzisweni kwamandla kagesi e-DC Ububanzi obuphezulu boshintsho (Tmin ≤ Ti ≤ Tmax) I-DC amandla okukhipha amandla kagesi ashintshayo ngokwenani lephesenti.
Mayelana Nemikhiqizo
Isilawuli samanje esithule kakhulu se-LM9036 sisebenzisa i-voltage ephansi yokuyeka kanye namandla aphansi kumodi yokulinda.Ngaphansi kuka-25µA Ground Pin yamanje ekulayisheni okungu-0.1mA, i-LM9036 ifaneleka ngokufanelekile kumasistimu ezimoto namanye asebenza ngebhethri.I-LM9036 igcina zonke izici ezivamile kuzilawuli zokuyeka ukuphuma eziphansi okuhlanganisa idivayisi yokudlula ephansi ye-PNP yokuyeka, ukuvikelwa kwesekethe emfushane, ukuvikelwa kwebhethri okuhlehlayo, nokuvalwa kokushisa.I-LM9036 inomkhawulo we-voltage osebenza kakhulu ongu-40V, i-−40°C kuya ku-+125°C izinga lokushisa lokusebenza, kanye no-±5% wokubekezelela i-voltage ephumayo kuwo wonke amandla okukhiphayo, i-voltage yokufaka, nebanga lokushisa.
