Soo bandhig
Korontada hagaha korantada caadiga ah waxay dhex martaa wareegga muunad si loo xakameeyo daminta/damida tuubbada hagaajinta korantada si loo beddelo caabbinta gudaha ee sahayda korantada si korantada culeysku u xasilo.
Bedeshada korantada nidaamiyaha korontada waa iyada oo la xakameynayo saamiga tuubada wareejinta ee shid iyo daminta si loo hagaajiyo tamarta wax soo saarka.
Faa'iidooyinka
Faa'iidooyinka beddelka sahayda korantada maamusha danab.
Faa'iidooyinka 1: isticmaalka tamarta hoose, waxtarka sare, cufan iyo fudud
Faa'iidada ugu weyni waa waxtarka sare.Xaaladda beddelka, transistor-ka laftiisu waxa uu qaataa hawl yar, maamulaha beddelka laftiisu waxa uu gaadhi karaa boqolkiiba toddobaatan ilaa siddeetan boqolkiiba waxtarka, isaga oo aan u baahnayn taransfoor-hoos u socda.Transformer-keeda wax-soo-saarkiisu wuxuu ku shaqeeyaa xawli sare oo mug ka yar 50 Hz ku jira IF transformer-ka.Wareegga xakamaynta beddelka, sidaas darteed, wuxuu leeyahay faa'iido dheeraad ah oo ah mid yar oo fudud.Waxa ay ku shaqayn kartaa in ka badan baaxad weyn oo danab ah.
Faa'iidada 2: Nidaamyada korantada ee kala duwan
Wax-soo-saarka danab ee ka soo baxa maamulaha beddelka waxa lagu nidaamiyaa wareegga waajibaadka calaamada kicinta, iyo isbeddellada ku yimaadda tamarta signalka waxa lagu magdhabi karaa habaynta soo noqnoqda ama ballaarinta.Sidan oo kale, marka la eego isbeddelada waaweyn ee tamarta korantada ee soo noqnoqda, waxay weli xaqiijin kartaa koronto wax soo saar oo xasilloon.Guud ahaan, kala duwanaanshaha danab ee sahayda beddelka waa mid aad u ballaaran iyo saameynta xasilinta danabku waa mid wanaagsan.
Faa'iidada 3: Foomamka wareegga dabacsan
Tusaale ahaan, waxaa jira is-xakameyn iyo kuwo kale oo xiiso leh, kala duwanaansho iyo soo noqnoqosho ah, hal-dhammeedka iyo laba-dhamaadka, iyo wixii la mid ah.Soosaarayaasha sahayda korontadu waxay ka faa'iidaysan karaan faa'iidooyinka noocyada kala duwan ee wareegyada si ay u naqshadeeyaan una horumariyaan maamulayaasha korantada ee buuxin kara codsiyada kala duwan.
Doorka
Laga soo bilaabo abuurista korontadu ilaa maanta, ku habboonaanta korontada waxaa la odhan karaa horumarka bulshada, nolosha dadku waxay keentay horumar iyo raaxo badan.Laakiin waxay noo keentaa raaxo isku mar, laakiin sidoo kale waxay noo keentaa dhibaato badan.Wax soo saarkeena si toos ah, waxaan inta badan la kulannaa xasillooni la'aanta tamarta, gaar ahaan bartamaha khadka, iyo sidoo kale inta lagu jiro xilliga ugu sarreeya ee korontada.Bulshada saxda ah ee sii kordheysa, haddii danabku aanu xasilloonayn, waxay dhib weyn u keeni doontaa nolosheenna wax-soo-saarka.Beddelka kaliya ee lagu beddeli karo wareegga ama beddelka goobta waa in la dejiyo qalab caawiye koronto ah.Iyo ilaa inta qalabka kaalmaynta korantadu ay khusayso, mishiinada ugu qaalisan uguna fudud waa xakamaynta tamarta.
Maalmihii hore, shaqada ugu weyn ee xakamaynta tamarta waxay ahayd in la dejiyo tamarta.Maamuluhu wuxuu kor u qaadi karaa danabka haddii ay dhacdo isbedbeddelka korantada aan degganayn, ama haddii ay dhacdo koronto yar, si loo hubiyo in qalabku si caadi ah u shaqeyn karo.Si kastaba ha ahaatee, iyada oo horumarinta tignoolajiyada, iyo sidoo kale dadka shuruudaha sii kordheysa ee qalabka.Xakamaynta tamarta maanta, ma aha oo kaliya inay hubiso in korantadu ay tahay mid caadi ah, laakiin sidoo kale waxay xaqiijiyaan badbaadada hawlgalka korontada.Sidaa darteed, marka lagu daro hubinta hawlgalka caadiga ah ee qalabka, xakamaynta korantada ayaa sidoo kale leh ilaalinta wareegga gaaban, ilaalinta wajiga gaaban, iyo hawlo kale oo badan oo ilaalin ah.
Halbeegyada ugu muhiimsan
Halbeegyada ugu muhiimsan ee xakamaynta korantada DC.
Awoodda korantada ee DC ee nidaamsan (voltage regulator) ee xuduudaha farsamada ee ugu muhiimsan waxaa loo qaybin karaa laba qaybood: mid waa tilmaamayaasha tayada, oo ka tarjumaysa mudnaanta korantada xasilinta korantada DC.Waxaa ka mid ah xasilloonida, iska caabin gudaha ah oo u dhiganta ( iska caabin wax soo saar leh), danab ripple, iyo heerkulka heerkulka.Qaybta kale waa tilmaanta sifaha, taas oo ka tarjumaysa sifooyinka dabiiciga ah ee sahayda korantada ee DC.Tusaale ahaan, input DC daneeya danab korontada, danab wax soo saarka, hadda wax soo saarka, iyo kala duwan ee nidaamka danab wax soo saarka.
1, heerka xakamaynta korantada ee SV
Heerka xakamaynta korantada waa tilmaame muhiim ah oo lagu garto waxqabadka korantada xasilinta korantada DC, oo sidoo kale loo yaqaan qodobka xasilinta ama qodobka xasilloonida.Waxaa lagu gartaa marka korantada wax-soo-saarka VI isbedesho marka xasilinta korantada DC-ga korantada wax-soo-saarka danab VO xasilloonida, oo badanaa lagu muujiyo boqolkiiba isbeddelka is-beddelka gelinta iyo wax-soo-saarka halbeegga tamarta wax-soo-saarka.
2, heerka hagaajinta hadda SI
Heerka nidaaminta hadda waa tilmaame weyn oo muujinaya awoodda culeyska ee xasiliyaha korantada DC, oo sidoo kale loo yaqaan qodobka xasilloonida hadda.Waxaa lagu gartaa marka danab wax-soo-saarka uu weli isbeddelin, korantada xasilinta korantada DC ay sabab u tahay isbeddelka culeyska hadda (output current), iyo isbedbeddelka korantada wax soo saarka ee ay keento awoodda xakamaynta, iyada oo la raacayo shuruudaha isbeddelka culeyska la cayimay, sida caadiga ah ayaa la muujiyay. sida boqolkiiba isbeddelka danab-soo-saarka halkii unug wax-soo-saarka danabka hadda jira ee heerka xakamaynta korantada DC ee sahayda korantada.
3,Rpple diidmada saamiga SR
Saamiga diidmada ripple waxay ka tarjumaysaa maamulaha danabka DC ee dhinaca soo gelista ee horudhaca awoodda diidmada korantada ugu weyn, marka gelinta korantada DC-ga iyo wax-soo-saarka qaybaha xakamaynta korantada DC ay weli is-bedesho, saamiga diidmada ripple waxaa inta badan lagu muujiyaa marka la eego soo-gelinta gelinta Korantada ugu sarreysa-ilaa-ugu sarreysa iyo wax-soo-saarka korantada ugu sarreysa-ilaa-ugu sarreysa, guud ahaan waxaa lagu muujiyey decibels, laakiin mararka qaarkood waxaa lagu muujin karaa boqolkiiba, ama si toos ah saamiga labada ayaa sheegay.
4,Xasiloonida heerkulka K
Xasiloonida heerkulka sahayda korantada DC ee isku dhafan waxa lagu qeexaa heerkulka shaqaynta ee DC ee ugu badnaan (Tmin ≤ Ti ≤ Tmax) Korontada DC ee soosaarka korontadu waxay isbeddeshaa qiimaha boqolkiiba.
Ku saabsan Alaabooyinka
Xakamaynta hadda jirta ee LM9036 ultra-hoose quiescent waxay muujisaa danab hoose oo hooseeya iyo hadda hooseeya ee qaabka heeganka.Iyada oo wax ka yar 25µA Ground Pin hadda ah oo culeyskiisu yahay 0.1mA, LM9036 wuxuu ku habboon yahay baabuurta iyo nidaamyada kale ee ku shaqeeya baytariga.LM9036 waxa ay haysaa dhammaan sifooyinka ay wadaagaan maamulayaasha ka tagista hoose oo ay ku jiraan aaladda kaarka PNP ee hoos u dhaca, ilaalinta wareegga gaaban, ilaalinta baytariga beddelka, iyo xidhitaanka kulaylka.LM9036 waxay leedahay 40V ugu badnaan xadka korantada shaqaynaysa, -40°C ilaa +125°C kala duwanaanta heerkulka hawlgalka, iyo ± 5% dulqaadka wax soo saarka ee hadda jira oo dhan, danab gelin, iyo kala duwanaanta heerkulka.
