Nuxurka Transformer-ka duulista ayaa ah inductor-ka isku xiran, kaydinta iyo sii-deynta tamarta ayaa loo fuliyaa si kale.
Dhaqanka caadiga ah ee soo saaraha loo isticmaalo kaydinta tamarta waa in la furo farqiga hawada.Transformers Flyback ma aha mid ka reeban.
Saamaynta furitaanka kala-baxa hawadu waa laba qaybood:
1) Xakamee inductance-ka, inductance ku habboon waxay buuxin kartaa shuruudaha naqshadeynta.
Inductance waa mid aad u weyn oo tamarta lama dallaci karo.Haddii inductance-ku aad u yar yahay, walbahaarka hadda jira ee tuubada beddelka ayaa kordhi doonta.
2) Yaree cufnaanta qulqulka magnetic B.
Iyadoo loo maleynayo in inductance, hadda iyo walxaha magnetic la go'aamiyay, kordhinta farqiga hawada waxay yareyn kartaa cufnaanta qulqulka shaqada ee inductor si looga hortago saturation.
Ka dib markaan fahamno shaqada furitaanka farqiga hawada, aan aragno haddii uu jiro koronto-bixiye flyback ah oo aan furin farqiga hawada?
Jawaabtu waxay tahay runtii ma jirto wax hawo ah.Waxaa jira qiyaas ahaan saddex xaaladood oo aan u baahnayn in la furo farqiga hawada.
A. Xuddunta birlabeedka dhabta ah ee la doortay ayaa aad uga weyn baahida dhabta ah.
Ka soo qaad inaad sameyso beddele 1W oo aad dooratid xudunta EE50, markaa itimaalka buuxsamida asal ahaan waa eber.
Looma baahna in la furo farqiga hawada.
B. Qalabka magnetic budada xudunta u ah ayaa la doortay, oo ay ku jiraan FeSiAl, FeNiMo iyo walxo kale.
Sababtoo ah maadada magnetic budada ah waxay u oggolaaneysaa cufnaanta qulqulka magnetic ee shaqeyneysa inay gaarto 10,000, taas oo aad uga sareysa 3,000 ee ferrite caadiga ah.
Kadibna iyada oo loo marayo xisaabinta saxda ah, looma baahna in la furo farqiga hawada mana la buuxin doono.Haddii xisaabinta aan loo samayn si sax ah, waxa laga yaabaa inay weli buuxsanto.
C. Qaladaadka naqshadaynta ama khaladaadka habaynta.
