Waa maxay inverter-ka?

Inverter-ku waa transformer DC ilaa AC ah, kaas oo dhab ahaantii ah hab rogitaan danab ah oo leh qalabka beddela. Beddeluhu wuxuu danabka AC ee shabakadda korontada u beddelaa wax soo saar 12V DC oo deggan, halka inverter-ku uu wax soo saarka danabka 12V DC u beddelo AC-ga danabka sare ee soo noqnoqda; labada qayboodba waxay sidoo kale isticmaalaan tignoolajiyada modulation-ka ballaca garaaca wadnaha (PWM) ee ugu badan ee la isticmaalo. Qaybta asaasiga ah waa koontaroole isku dhafan oo PWM ah, adapter-ku wuxuu adeegsadaa UC3842, inverter-kuna wuxuu isticmaalaa jajabka TL5001. Kala duwanaanshaha danabka hawlgalka ee TL5001 waa 3.6~40V, waxayna leedahay amplifier qalad ah, nidaamiye, oscillator, matoor PWM ah oo leh xakamaynta aagga dhintay, wareegga ilaalinta danabka hoose iyo wareegga ilaalinta wareegga gaaban.

Qaybta is-dhexgalka gelinta: Qaybta gelinta waxay leedahay 3 calaamadood, 12V DC gelinta VIN, ENB-ga firfircoon ee shaqeynaya iyo calaamadda xakamaynta hadda ee guddiga DIM. VIN waxaa bixiya Adaptor-ka, danabka ENB-na waxaa bixiya MCU oo ku taal motherboard-ka, qiimaheeduna waa 0 ama 3V. Marka ENB=0, inverter-ku ma shaqeeyo, marka ENB=3V, inverter-ku wuxuu ku jiraa xaalad shaqo oo caadi ah; danabka DIM-na waxaa bixiya motherboard-ka, kala duwanaanshaha kala duwanaanshihiisuna waa inta u dhaxaysa 0 iyo 5V. Qiimayaasha DIM ee kala duwan waxaa dib loogu celiyaa dhammaadka jawaab celinta ee koontaroolaha PWM, hadda uu inverter-ku siiyo culayska ayaa sidoo kale ka duwanaan doona. Inta uu yar yahay qiimaha DIM, ayaa sii weynaysa wax soo saarka hadda ee inverter-ku.

Wareegga bilowga danabka: Marka ENB uu sarreeyo, danab sare ayaa la soo saaraa si loo shido tuubada iftiinka dambe ee Guddiga.

Xakameeyaha PWM: Waxay ka kooban tahay hawlaha soo socda: danabka tixraaca gudaha, amplifier-ka qaladka, oscillator-ka iyo PWM, ilaalinta danabka xad-dhaafka ah, ilaalinta danabka hoos u dhaca, ilaalinta wareegga gaaban, iyo transistor-ka wax soo saarka.

Beddelka DC: Wareegga beddelka danabka wuxuu ka kooban yahay tuubada MOS iyo inductor-ka kaydinta tamarta. Garaaca gelinta waxaa xoojiya amplifier-ka riixa wuxuuna kaxeeyaa tuubada MOS si uu u sameeyo ficil beddelaad, si danabka DC uu u dallaco oo uu u daayo inductor-ka, si dhammaadka kale ee inductor-ku u helo danabka AC.

Wareegga LC iyo wareegga wax soo saarka: hubi in danab 1600V loo baahan yahay si laambaddu u shaqeyso, oo danab-ka hoos u dhig ilaa 800V ka dib marka laambaddu shaqeyso.

Jawaab celinta danabka soo baxaya: marka culaysku shaqeynayo, danabka muunadda ayaa dib loogu shubaa si loo xasiliyo wax soo saarka danabka ee inverter-ka I.

Shaqada
Beddelaha korontada (inverter) wuxuu korontada DC (batariga, baytariga kaydinta) u beddelaa koronto AC ah (guud ahaan 220v50HZ sine ama mowjad laba jibbaaran). Marka loo eego dadka caadiga ah, beddelaha korontada (inverter) waa qalab u beddela hadda tooska ah (DC) una beddela hadda beddelan (AC). Waxay ka kooban tahay buundo beddelan, macquulka xakamaynta iyo wareegga shaandhada.
Si fudud haddii loo dhigo, qalabka wax lagu beddelo waa qalab elektaroonik ah oo danab hooseeya (12 ama 24 volts ama 48 volts) u beddela awoodda DC 220 volts AC. Sababtoo ah awoodda AC 220 volts badanaa waxaa loo hagaajiyaa awoodda DC si loo isticmaalo, doorka qalabka wax lagu beddelona waa liddi ku ah, sidaas darteed magaca. Xilligii "dhaqdhaqaaqa", xafiiska moobaylka, isgaarsiinta moobaylka, madadaalada moobaylka iyo madadaalada. Marka la socdo, ma aha oo kaliya in loo baahan yahay danab toos ah oo hooseeya oo laga helo baytariyada ama baytariyada kaydinta, laakiin sidoo kale koronto beddelan oo 220-volt ah, taas oo lagama maarmaan u ah nolol maalmeedka. Qalabka wax lagu beddelo ayaa dabooli kara baahiyahan.
