Faahfaahinta Alaabta

Tags Product

MOSFET-da-sare ee P-channel MOSFET waxay ku shaqayn kartaa 100% wareegga waajibaadka korantada ugu hooseysa oo uma baahna capacitor bootstrap ee wadista albaabka.Sidoo kale, barta xaddidan ee hadda la isku hagaajin karo si loo wanaajiyo xulashada inductor ee baahi gaar ah oo hadda jirta.Ikhtiyaarada wakhtiga bilawga ah ee la dooran karo iyo kuwa la hagaajin karo waxaa ka mid ah daahitaanka ugu yar (bilowga jilicsan ma jiro), gudaha go'an (900 µs), iyo bilawga debedda ee jilicsan ee la isticmaalayo capacitor.Tusiyaha PGOOD-furan waxaa loo isticmaali karaa isku xigxiga, warbixinta khaladka ah, iyo la socodka tamarta wax soo saarka.Beddeliyaha buck LM5165 waxaa lagu heli karaa 10-pin, 3-mm × 3-mm, kuleyl-ku-kordhinta xirmada VSON-10 oo leh 0.5-mm pin garoon.

Bedelida Nidaamiyeyaasha

1.Waa maxay Beddelaada Regulators:
Xakamaynta danabku waa aalad ka dhigaysa korantada wax soo saarka mid xasiloon oo ka kooban wareegga xakamaynta tamarta, wareegga kontoroolka, iyo matoorka servo.Marka korantada wax gelinta ama culeysku is beddelo, maamulaha ayaa tijaabinaya muunadaha wareegga wareegga, isbarbardhigga oo kordhiyaa, ka dibna u kaxeeya matoorka servo si uu u wareego si booska burushka kaarboonka uu isu beddelo.Waxa ay ku ilaalisaa korantada wax-soo-saarka mid xasiloon iyadoo si toos ah u hagaajinaysa saamiga gariiradda.
Nidaamiyaha wareejinta waxaa loo isticmaalaa in lagu dhaliyo danab wax soo saarka iyadoo la xakameynayo transistor-ka si loogu beddelo inta u dhexeysa gobolka ON, iyo gobolka OFF iyo qaybaha kaydinta tamarta (capacitors iyo inductors) si loo ilaaliyo korantada mid deggan.Waxaa lagu hagaajiyaa iyadoo la hagaajinayo waqtiga beddelka iyadoo loo eegayo muunadaha jawaab-celinta ee danabka wax soo saarka.

Hordhaca shaqada

Xakamaynta danabku waa nooc ka mid ah wareegga sahayda korantada ama qalabka korontada oo si toos ah u hagaajin kara tamarta wax soo saarka.Doorka maamulaha danabku waa inuu isbeddelaa oo aan ku habboonayn shuruudaha qalabka korantada si loo dejiyo korantada korantada ee qiyaasta qiimaha loo dejiyay si wareegyada kala duwan ama qalabka korantada ay si caadi ah ugu shaqeeyaan tamarta shaqada ee la qiimeeyay.

Baaxadda codsiga

Xakamaynta korantada ayaa si weyn loogu isticmaali karaa warshadaha iyo shirkadaha macdanta, beeraha saliida, tareenada, goobaha dhismaha, dugsiyada, isbitaalada, cilmi baarista sayniska, iyo meelaha kale ee u baahan xasilloonida tamarta korontada.Waxa kale oo lagu habeeyey kombuyuutarrada elektiroonigga ah, qalabka mishiinnada saxda ah, sawir-qaadista kombiyuutarka (CT), qalabka saxda ah, qalabka tijaabada, nalalka wiishka, qalabka dibadda laga keeno, khadadka wax soo saarka, iyo qalab kale.Intaa waxaa dheer, nidaamiyaha danabku wuxuu sidoo kale ku habboon yahay korantada korantada ee hooseeya ama sare, isbeddelka dhamaadka shabakada qaybinta hooseeya ee isticmaalayaasha, iyo isbeddelka culeyska ee qalabka korontada.Xakamaynta danabku wuxuu si gaar ah ugu habboon yahay dhammaan shuruudaha sare ee hirarka qaabaynta korantada ee meelaha korantada.Xakamaynta awooda sare ee magdhawga tamarta waxaa lagu xidhi karaa kuleyl, biyo-dhaliye, iyo koronto-dhaliyeyaal yar yar.

Kala soocidda

Marka loo eego dabeecadda kala duwan ee wax soo saarka maamulaha, nidaamiyaha guud ahaan waxaa loo qaybiyaa AC regulator (AC korantada xasilinta korantada) iyo regulator DC (Xasilinta korantada DC) laba qaybood.
Xakamaynta korantada AC: Xakameeyaha danabku wuxuu leeyahay tobanaan ilaa kun oo kilowatts oo ah xakamaynta korantada AC, waa sahayda tijaabinta waaweyn iyo warshadaha, awooda shaqada qalabka caafimaadka.Waxa kale oo jira hagayaasha korantada AC yar ee dhowr watts ilaa dhowr kilowatts, kuwaas oo loogu talagalay shaybaarada yaryar ama qalabka guriga si ay u bixiyaan awood tayo sare leh.
Nidaamiyeyaasha DC: Marka loo eego xaaladda hawlgalka ee tuubada hagaajinta, maamulayaasha DC waxay inta badan u qaybsan yihiin laba qaybood: alaabada iyo maamulayaasha beddelka.Dib-u-habeeyaha beddelka, wareegga wareegga wuxuu leeyahay nooca gelinta capacitor iyo nooca gariiradda gariiradda gelinta nooca laba nooc, waxay u baahan yihiin inay noqdaan kuwo dabacsan iyadoo loo eegayo habka wareegga wareegga beddelka ee loo isticmaalo.Nooca gelinta gariiradda choke waxaa loo isticmaalaa hoos-hoos u-dejinta xeerbeegtida, halka nooca gelinta capacitor-ka loo isticmaalo hab-bedesha kor u kaca.
Alaabtani waa beddele tallaabo-hoos u kacaya.
