Iziseko zeeTransformers Cores

Ii-cores ze-transformers zihlala zenziwe ngezinto ze-ferromagnetic ezine-magnetic permeability ephezulu. Injongo ephambili ye-core kukubonelela ngesekethe ye-magnetic evaliweyo kwinkqubo yokungenisa i-electromagnetic evumela ukuguqulwa kwe-voltage. I-transformer ine-coil yokuqala, i-coil yesibini, kunye ne-core edibanisa zona.

Imilo ye-core ingahluka, kunye noqwalaselo oluqhelekileyo oluquka i-E, i-I, i-U, kunye ne-toroidal cores. I-magnetic field eveliswa yi-primary winding ivelisa i-flux, ethi emva koko idlule kwi-core ize ibangele umsinga kwi-secondary winding. Olu dluliselo lwamandla lulo oluvumela ukuguqulwa kwe-voltage.

Ukukhethwa kwezinto eziphambili kubalulekile kuba kuchaphazela ukusebenza kakuhle kunye nokusebenza kwe-transformer.
