Ngaphezu koko, ii-U-core transformers zigqwesile kwizicelo ezifuna umlinganiselo wokuguqulwa kwe-voltage ephezulu. Uyilo lwe-U-core luvumela ukufakelwa kombane okusebenzayo phakathi kwee-windings, okuvumela ukuveliswa kwe-voltage ephezulu ngaphandle kokukhutshwa kwe-corona okanye ukuphazamiseka kwe-insulation. Olu buchule luluncedo kwiinethiwekhi zothumelo kunye nezicelo ezinkulu zemizi-mveliso.

3. I-Toroidal Transformer

I-transformer ye-toroidal ine-core efana ne-donut okanye i-toroidal. Ngokungafaniyo nee-transformers ze-E-core kunye ne-U-core, ayinazo ii-laminations ezahlukeneyo kodwa endaweni yoko yenziwe nge-strip eqhubekayo yezinto ze-magnetic. Olu yilo lubonelela ngeenzuzo ezininzi, kubandakanya i-compact form factor, i-superior magnetic flux containment, kunye nokuphazamiseka kwe-electromagnetic okuncitshisiweyo.

Enye yeenzuzo eziphambili ze-toroidal transformer kukusebenza kwayo okuphezulu okubangelwa yindlela eqhubekayo yemagnethi kunye nezithuba ezincinci zomoya phakathi kwee-windings. Ukungabikho kwezithuba zomoya kunciphisa kakhulu ilahleko, okwenza ii-toroidal transformers zilungele usetyenziso olufuna ukusebenza okuphezulu kunye nokusetyenziswa kwamandla okuphantsi, njengee-amplifiers zesandi kunye nezixhobo zonyango.

4. Isiguquli seRing-Core

I-transformer ye-ring-core ine-core esisilinda ene-primary windings kunye ne-secondary windings ezijikelezileyo. Olu yilo lubonelela nge-magnetic coupling egqwesileyo, ukuvuza okuphantsi komoya, kunye nokulahlekelwa okuncitshisiweyo kwe-winding, okubangela ukusebenza kakuhle okuphezulu.
