Izinto ezisetyenziswa kwiiTransformers zeSigaba eSithathu:

Umongo

I-core yinxalenye ebalulekileyo ye-transformer enamanqanaba amathathu, enoxanduva lokunceda ukudluliselwa kwamandla emagnethi phakathi kwee-windings eziphambili nezesibini. Ngokwesiqhelo yenziwe ngee-laminations zesinyithi ze-silicon eziphezulu, ezihlanganiswe ndawonye ukunciphisa ilahleko yamandla e-eddy. I-core ijikeleze ii-windings kwaye ibonelela ngendlela engathandekiyo yokuba i-magnetic flux ihambe, ukuqinisekisa ukudluliselwa kwamandla ngokufanelekileyo.
