Yazisa
Unikezelo lwamandla ombane oqhelekileyo olawula umbane luhamba ngesampulu yesekethe yokulawula i-on/off yetyhubhu yokulawula unikezelo lwamandla ukuguqula ukuchasana kwangaphakathi konikezelo lwamandla ukuze i-voltage kumthwalo izinzile.
Ukutshintsha unikezelo lwamandla olawulo lwamandla kulawulo lomyinge wetyhubhu yokutshintsha kunye nokucima ukulungelelanisa umbane wokuphuma.
Iingenelo
Iinzuzo zokutshintsha umbane wolawulo lombane.
Izinto eziluncedo 1: ukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle okuphezulu, i-compact kunye nekhaphukhaphu
Inzuzo yayo enkulu kukusebenza okuphezulu.Kwimeko yokutshintsha, i-transistor ngokwayo idla umsebenzi omncinci, kwaye umlawuli wokutshintsha ngokwawo unokufikelela kumashumi asixhenxe ukuya kwamashumi asibhozo ekhulwini, ngelixa engadingi i-transformer-down-down.I-transformer yayo yokuphuma isebenza kwiifrikhwensi eziphezulu kunye nomthamo ongaphantsi kwe-50 Hz kwi-IF transformer.Isiphaluka somlawuli wokutshintsha, ngoko ke, sinenzuzo eyongezelelweyo yokuba yincinci kwaye ilula.Inokusebenza kuluhlu olubanzi lwamandla ombane.
I-Advanteji yesi-2: Uluhlu olubanzi lolawulo lwamandla ombane
Imveliso ye-voltage evela kumlawuli wokutshintsha ilawulwa ngumjikelezo womsebenzi wesignali yokuvuselela, kwaye utshintsho kwi-voltage ye-input signal inokuhlawulwa ngokumodareyitha rhoqo okanye ukwandisa.Ngale ndlela, kwimeko yotshintsho olukhulu kwi-voltage yegridi yefrikhwensi, isenokuqinisekisa umbane wokuphuma ozinzile.Ngokubanzi, uluhlu lwamandla ombane wokutshintsha kombane lubanzi kakhulu kwaye umphumo wokuzinzisa umbane ulungile.
I-Advantage 3: Iifom zesekethe eziguquguqukayo
Ngokomzekelo, kukho u-self-excited and other-excited, wide-ranging and frequency-regulated, single-end and double-end, njalo njalo.Abaphuhlisi bobonelelo lwamandla banokusebenzisa izibonelelo zeentlobo ezahlukeneyo zeesekethe ukuyila kunye nokuphuhlisa izilawuli zokutshintsha kwamandla ombane ezinokuhlangabezana nezicelo ezahlukeneyo.
Indima
Ukususela ekuyilweni kombane ukuza kuthi ga namhlanje, ukulungelelaniswa kombane kunokuthiwa ngophuhliso loluntu, ubomi babantu buye bazisa inkqubela eninzi kunye nokulula.Kodwa kusizisela lula ngaxeshanye, kodwa kusizisela iingxaki ezininzi.Kwimveliso yethu iphila, sihlala sidibana nokungazinzi kwe-voltage, ngakumbi phakathi komgca, kunye nakwixesha eliphezulu lombane.Kuluntu olukhula ngokuchaneka okuphezulu, ukuba i-voltage ayizinzanga, iya kuzisa ukuphazamiseka okukhulu kubomi bethu bemveliso.Eyona ndlela yodwa yokutshintsha isiphaluka okanye ukutshintsha indawo kukuseka isixhobo sombane esincedisayo.Kwaye ngokubhekisele kwizixhobo ezincedisayo zombane, oyena matshini uxabisa kancinci kwaye ulula kakhulu sisilawuli sombane.
Ngeentsuku zokuqala, umsebenzi ophambili we-voltage regulator yayikukuzinzisa umbane.Umlawuli unokunyusa amandla ombane xa kukho ukuguquguquka kwamandla ombane okungazinzanga, okanye kwimeko yombane ophantsi, ukuqinisekisa ukuba isixhobo sinokusebenza ngokuqhelekileyo.Nangona kunjalo, ngophuhliso lwetekhnoloji, kunye neemfuno zabantu ezikhulayo zezixhobo.Abalawuli be-voltage banamhlanje, abaqinisekisi kuphela ukuba i-voltage iyinto eqhelekileyo, kodwa iqinisekisa ukhuseleko lokusebenza kombane.Ke ngoko, ukongeza ekuqinisekiseni ukusebenza okuqhelekileyo kwesixhobo, isilawuli sombane sikwanalo nokhuseleko lwesekethe emfutshane, ukhuseleko lwesigaba esifutshane, kunye neminye imisebenzi emininzi yokhuseleko.
Iiparamitha eziphambili
Iiparamitha eziphambili ze-DC voltage regulator.
Unikezelo lwamandla olulawulwa yi-DC (i-voltage regulator) yeeparamitha ezingundoqo zobugcisa zinokwahlulwa zibe ziindidi ezimbini: enye yimiqondiso yomgangatho, ebonisa ukufaneleka konikezelo lombane lokuzinzisa umbane weDC.Iquka ukuzinza, ukuxhathisa okulinganayo kwangaphakathi (ukuchasana kwemveliso), i-voltage ye-ripple, kunye ne-coefficient yokushisa.Olunye udidi luphawu lwesalathisi, esibonisa iimpawu zendalo zobonelelo lwamandla olulawulwa yi-DC.Umzekelo, igalelo le-DC elilawula amandla ombane wombane, amandla ombane aphumayo, imveliso yangoku, kunye noluhlu lolawulo lombane oluphumayo.
1, izinga lolawulo lombane SV
Umyinge wolawulo lwe-voltage luphawu olubalulekileyo lokubonisa ukusebenza kombane wokuzinzisa umbane we-DC, okwaziwa ngokuba yi-stabilization factor okanye uzinzo.Ibonakaliswa xa igalelo lombane we-VI litshintsha xa i-DC yozinziso lombane wokuphuma kwamandla ombane i-VO uzinzo, idla ngokuchazwa njengepesenti yotshintsho olwenziwayo kwigalelo kunye nemveliso yombane ngeyunithi yombane ophumayo.
2, izinga lohlengahlengiso lwangoku SI
Izinga lolawulo lwangoku luphawu oluphambili lomthamo we-DC voltage stabilizer, eyaziwa ngokuba yinto yokuzinza yangoku.Ibonakaliswa xa igalelo lombane lihlala lingatshintshi, unikezelo lwamandla ombane weDC wokuzinzisa amandla ombane ngenxa yotshintsho kumthwalo wangoku (imveliso yangoku), kunye nokuguquguquka kwamandla ombane okubangelwa kukucinezelwa kwamandla, phantsi kweemeko zotshintsho oluchaziweyo lwangoku, oluqhele ukubonakaliswa. njengepesenti yotshintsho kumbane ophumayo kwiyunithi yemveliso yombane weyunithi isantya solawulo lwangoku lonikezelo lombane lokuzinzisa umbane weDC.
3,Rpple ukwala umlinganiselo SR
Umlinganiselo wokwaliwa kwe-ripple ubonisa umlawuli wombane we-DC kwicala legalelo lokwaziswa kwesakhono sokulahlwa kombane ongundoqo, xa igalelo lolawulo lombane we-DC kunye nemveliso ye-DC yolawulo lwe-voltage amacandelo ahlala engatshintshi, umlinganiselo wokwaliwa kwe-ripple udla ngokubonakaliswa ngokwemigaqo yokufaka i-ripple. Incopho yombane ukuya kwincopho yombane kunye nesiphumo somthamo wombane wencopho-ukuya-kwincopho yombane, ebonakaliswa ngokubanzi ngeedecibels, kodwa ngamanye amaxesha inokubonakaliswa njengepesenti, okanye ngokuthe ngqo kunye nomlinganiselo wezi zibini zixeliweyo.
4,Uzinzo lobushushu K
Uzinzo lobushushu lonikezelo lwamandla ombane oluhlanganisiweyo lwe-DC lucaciswe kwi-DC yonikezelo lwamandla ombane osebenzayo ubushushu be-Ti ubuninzi botshintsho (Tmin ≤ Ti ≤ Tmax) Umbane we-DC wemveliso yombane wemveliso yombane ohambelana nokutshintsha kwexabiso lepesenti.
Malunga neeMveliso
I-LM9036 i-ultra-low-low quiescent regulator yangoku ibonisa i-voltage ephantsi yokuyeka kunye ne-low current kwimo yokulinda.Ngaphantsi kwe-25µA Ground Pin yangoku kumthwalo we-0.1mA, i-LM9036 ifanelekele ngokufanelekileyo iimoto kunye nezinye iinkqubo ezisebenza ngebhetri.I-LM9036 igcina zonke iimpawu eziqhelekileyo kubalawuli be-dropout ephantsi kuquka i-PNP yokupasa ephantsi isixhobo, ukukhuselwa kwesiphaluka esifutshane, ukukhuselwa kwebhetri umva, kunye nokuvalwa kwe-thermal.I-LM9036 inomlinganiselo we-40V ophezulu wokusebenza kwamandla ombane, i-−40 ° C ukuya ku- +125 ° C ububanzi bokushisa obusebenzayo, kunye ne-± 5% yokunyamezela kwamandla ombane phezu kwayo yonke imveliso yangoku, i-voltage yegalelo, kunye noluhlu lobushushu.
