N'iji ike inductor dị ka ihe atụ, a na-ewebata ihe ndị bụ isi nke inductor.

uru inductance

The isi oke nke inductance bụkwa ihe dị mkpa oke na-emetụta ripple ugbu a na ibu nzaghachi.

Ihe dị ugbu a nke inductor ike na ihe ntụgharị bụ triangle wave ugbu a. Na mkpokọta, enwere ike ịtọ ripple ugbu a na ihe dịka 30% nke ibu dị ugbu a. Ya mere, ọ bụrụhaala na ekpebie ọnọdụ nke onye ntụgharị, enwere ike ịgbakọ inductance kwesịrị ekwesị nke ike inductor.

A na-akpọkwa njirimara saturation dị ugbu a DC njirimara superposition, nke na-emetụta inductance dị irè mgbe onye inductor na-arụ ọrụ. Ọ bụrụ na ahọrọghị inductor nke ọma, onye inductor dị mfe iji jupụta, na-eme ka uru inductance n'ezie belata, enweghị ike imezu ihe ndị a chọrọ, ma nwee ike ịgbanyụ sekit ahụ.
