U beddel AC una beddel DC
Waxaa jira laba nooc: nooca gelinta capacitor iyo nooca gariiradda gariiradda choke. Inta badan sahayda korontadu waa kuwii hore
1.2 Wareegga beddelka
Waxay ka kooban tahay wareegga beddelka, go'doominta wax soo saarka, iwm. Waa kanaalka ugu muhiimsan ee loogu talagalaywareejinta korontadabeddelidda, oo dhammaystirta wax-ka-beddelka goynta iyo soo-saarka mawjadaha korantada ee qaab-dhismeedka awoodda.
Tuubbada korantada ee heerkan oo kale waa qalabkeeda asaasiga ah.
1.2.1 Wareegga wareejinta
Habka wadista: is-macnaha, dibadda u faraxsan
Wareegga beddelka: go'doon, aan go'doon ahayn, resonant
Qalabka korontada: Kuwa ugu badan ee la isticmaalo waa GTR, MOSFET, IGBT
Habka habaynta: PWM, PFM, iyo hybrid. PWM waa tan ugu badan ee la isticmaalo.
1.2.2 wax soo saarka Converter
U qaybsan oo usha-free iyo usheeda dhexe leh. Usha looma baahna hagaajinta mawjada badhkeed iyo hagaajinta hadda-laba-jibbaaran. Shaft ayaa looga baahan yahay mawjada buuxda.
1.3 Xakamaynta wareegga
Sii garaaca afar xagal la habeeyay wareegga wadista si loo hagaajiyo tamarta wax soo saarka.
Wareegga tixraaca: Bixi tixraac danab. Sida tixraaca barbar socda LM358, AD589, tixraac taxane AD581, REF192, iwm.
Wareegga muunadda: Qaado dhammaan ama qayb ka mid ah danabka wax soo saarka.
Isbarbardhigga isbarbardhigga: Is barbar dhig calaamadda muunadda iyo calaamadda tixraaca si aad u abuurto calaamad khalad ah oo lagu xakameynayo wareegga korontada PM.
Beddelka V/F: U beddel calaamadda korantada ee khaladka ah signalka soo noqnoqda.
Oscillator: Samee mowjadda oscillation-sare
Wareegga wadista saldhiga: U beddel calaamada oscillation-ka ee la habeeyey una beddel calaamad kontorool ku habboon si loo kaxeeyo saldhigga tuubada beddelka.
1.4 Wareegga wax soo saarka
Sixitaan iyo shaandhayn
Ku hagaaji tamarta wax soo saarka si aad u garaacdo DC una simi danab yar oo DC ah. Tiknoolajiyada hagaajinta wax soo saarka hadda waxay leedahay mawjad badhkeed, hir buuxa, awood joogto ah, labanlaabmida hadda, isku-dhafka iyo hababka kale ee sixitaanka.
(B) Falanqaynta saadka tamarta sare ee kala duwan
2.1 Beddeliyaha
Wareegga Buck: Buck chopper, gelinta iyo soo saarista polarity waa isku mid.
Mar haddii sheyga labaad ee volt-labaad ee kharashka inductor iyo sii dayntu ay le'eg tahay xaalad joogto ah, danab gelin Ui, danab wax soo saarka Uo; sidaas darteed:
(Ui-Uo)ton=Uotoff
Uiton-Uoton=Uo*toff
Ui*ton=Uo(ton+toff)
Uo/Ui=ton/(ton+toff)=▲
Taasi waa, xidhiidhka korantada wax-soo-saarka iyo wax-soo-saarka waa:
Uo/Ui=▲ (wareegga waajibaadka)
Topology wareegga wareegga Buck
Marka daaranadda daarto, awoodda wax gelinta waxaa shaandheeya L inductor iyo capacitor-ka C si loo bixiyo hadda ilaa dhammaadka rarka; marka daaranuhu damiyo, inductor-ka L waxa uu sii wadaa in uu dhex socdo diode-ka si uu culaysku hadda u sii socdo. Danabka wax soo saarku kama badnaan doono danabka wax-soo-saarka ee wareegga shaqada awgeed.
2.2 Beddelka Kobcinta
Wareegga Kobcinta: Kor-u-qaadista chopper-ka, soo-gelinta iyo soo-saarka polarity waa isku mid.
Isticmaalka isla habka, marka loo eego mabda'a ah in dallacaadda iyo soo daynta sheyga labaad ee volt-labaad ee inductor L ay la mid yihiin xaalad joogto ah, xiriirka danab waxaa laga soo saari karaa: Uo/Ui=1/(1-▲）)
Kordhinta wareegga wareegga
Tuubada beddelka Q1 iyo culayska wareeggan ayaa si is barbar socda isugu xidhan. Marka tubbada beddelka la shido, hadda waxa uu soo maraa inductor L1 si uu mawjada u simo, sahayda korontaduna waxa ay dalacaysaa inductor L1. Marka tuubbada furaha la damiyo, inductor L wuxuu ku soo daayaa culeyska iyo korontada, korantada wax soo saarku waxay noqon doontaa danab galiyaha Ui + UL, sidaa darteed waxay leedahay saameyn kor u kac ah.
2.3 Flyback Converter
Kor-u-qaadista Wareegga: Kobcinta/Buck Chopper, gelinta iyo wax soo saarka ayaa ka soo horjeeda, iyo inductor-ka waa la kala qaadaa.
Xiriirka Voltage: Uo/Ui=-▲/(1-▲)
Kor-u-qaadista Sare ee wareegga wareegga
Marka S uu shido, sahayda korantada culaysku waxa ay dalacaysaa inductor-ka. Marka S uu maqan yahay, sahayda korontada ayaa lagu sii daayaa culeyska iyada oo loo marayo inductors si loo gaaro gudbinta korontada.
Sidaa darteed, L inductor-ka halkan waa aaladda gudbinta tamarta.
(C) Goobaha codsiga
Wareegga korantada wareejinta wuxuu leeyahay faa'iidooyinka waxtarka sare leh, cabbir yar, miisaan fudud, iyo korantada wax soo saarka deggan, sidaas darteed waxaa si ballaaran loogu isticmaalaa isgaarsiinta, kombiyuutarada, automation warshadaha, qalabka guriga iyo meelaha kale. Tusaale ahaan, goobta kombuyuutarka, sahayda wareejinta waxay noqotay qaybta ugu muhiimsan ee korontada kombuyuutarka, taas oo xaqiijin karta hawlgalka xasilloon ee qalabka kombiyuutarka; Dhinaca tamarta cusub, sahayda korantada ee beddesha ayaa sidoo kale ka ciyaaraysa door muhiim ah sida qalab si xasilan u beddeli kara tamarta.
Marka la soo koobo, wareegga sahayda korantada ee wareejinta waa wareeg beddelaad awood wax ku ool ah oo la isku halayn karo. Mabda'eeda shaqadu waa inta badan in ay u beddesho tamarta korantada wax soo saarka si deggan oo la isku halayn karo iyada oo loo marayo beddelka beddelka soo noqnoqoshada sare iyo shaandhaynta.
