Horumarka tignoolajiyada casriga ah, soo ifbaxa rogrogayaasha ayaa siisay wax badan oo ku habboon nolosha qof kasta, haddaba waa maxay rookaha?Sidee buu u shaqeeyaa beddelka?Asxaabta tan danaynaysa kaalay oo isla ogaada.
Waa maxay rookaha:
Inverter-ku wuxuu u beddelaa awoodda DC (bateriga, baytariga kaydinta) tamarta AC (guud ahaan 220V, 50Hz wave sine).Waxay ka kooban tahay buundada inverter, xakamaynta macquulka iyo wareegga filter.Si ballaaran loo isticmaalo qaboojiyaha, tiyaatarada guriga, giraangiraha shiida ee korontada, qalabka korontada, mishiinada tolida, DVD, VCD, kombiyuutarada, TV-yada, mashiinka dharka, koofiyadaha kala duwan, qaboojiyaha, VCR-yada, duugista, marawaxadaha, nalalka, iwm ee dalalka shisheeye, ay sabab u tahay. ilaa heerka sare ee baabuurta, inverter-ka waxa loo isticmaali karaa in lagu xidho batari si loogu kaxeeyo qalabka korontada iyo qalabka kala duwan si ay u shaqeeyaan marka aad baxdo shaqada ama safarka.
Mabda'a shaqada beddelka:
Inverter-ku waa beddelka DC ilaa AC, kaas oo runtii ah geedi socod koronto oo rogaal celis ah.Beddeliyuhu wuxuu u beddelaa korantada AC ee korantada korantada 12V DC wax soo saarka oo deggan, halka beddeliyuhu u beddelayo wax soo saarka korantada 12V DC Adapter-ka oo u beddelaya kororka sare ee AC;Labada qayboodba sidoo kale waxay isticmaalaan farsamooyin badan oo la isticmaalo pulse width modulation (PWM).Qaybteeda udub-dhexaadka ah waa kontaroolaha isku dhafan ee PWM, Adapter-ku wuxuu isticmaalaa UC3842, iyo rogrogu wuxuu isticmaalaa chip TL5001.Kala duwanaanshaha korantada shaqada ee TL5001 waa 3.6 ~ 40V.Waxay ku qalabaysan tahay cod-weyneeye qalad, nidaamiye, oscillator, koronto-dhaliye PWM oo leh kantaroolka aagga dhintay, wareegga ilaalinta korantada hooseeya iyo wareegga ilaalinta wareegga gaaban.
Qaybta dhex gelinta:Waxaa jira 3 calaamadood oo ku jira qaybta wax-gelinta, 12V DC input VIN, shaqada awood u siinaysa ENB iyo calaamadda kontoroolka hadda ee Panel DIM.VIN waxaa bixiya Adapter-ka, ENB Voltage-ka waxaa bixiya MCU-ga Motherboard-ka, qiimihiisa waa 0 ama 3V, marka ENB=0, inverter-ku ma shaqeeyo, marka ENB=3V, inverter-ku wuxuu ku jiraa xaalad shaqo oo caadi ah;halka korontada DIM ay bixiso guddiga ugu weyn, kala duwanaanshuhu wuxuu u dhexeeyaa 0 iyo 5V.Qiimayaasha kala duwan ee DIM ayaa dib loogu celinayaa terminalka jawaab celinta ee kontaroolaha PWM, iyo hadda ay bixiso rogaha culeyska ayaa sidoo kale ka duwanaan doona.Inta yar ee qiimaha DIM, waa yaraanta wax soo saarka hadda ee beddelka.ka weyn.
Wareegga bilawga korantada:Marka ENB ay ku jirto heer sare, waxay soo saartaa danab sare si ay u iftiimiso tubbada iftiinka dambe ee guddiga.
PWM xakameeyaha:Waxay ka kooban tahay hawlaha soo socda: korantada tixraaca gudaha, cod-weyneeye qalad, oscillator iyo PWM, ilaalinta xad-dhaafka ah, ilaalinta korantada, ilaalinta wareegga gaaban, iyo transistor saarka.
Beddelka DC:Wareegga beddelka danabku wuxuu ka kooban yahay tuubada beddelka MOS iyo inductctor kaydinta tamarta.garaaca garaaca garaaca waxaa xoojisay cod-weyneeye riix-jiid ka dibna u kaxeeya tuubada MOS si ay u qabato ficil beddelka, si korantada DC ay u dalacdo oo ay u soo saarto inductor-ka, si dhamaadka kale ee inductor uu u helo koronto AC.
LC oscillation iyo wareegga wax soo saarka:hubi koronta 1600V ee looga baahan yahay laambad si uu u bilaabo, oo yareeya danabka ilaa 800V ka dib marka nalka la bilaabo.
Soo-celinta danab-celinta:Marka uu culaysku shaqaynayo, korantada muunadda ayaa dib loo soo celinayaa si loo dejiyo wax soo saarka danab-rogeeyaha.
