Ọla kọpa waya ferrite isi eriri igwe inductor maka GPS

Ferrite bụ naanị ntụ ntụ nke oxides nke ígwè.A na-agwakọta ntụ ntụ a na resin epoxy ma kpụzie ya ka ọ bụrụ cores nke enwere ike imerụ wires gburugburu.Ferrite core inductor bụ ndị a na-amata nke ọma n'ihi agba ntụ isi awọ.Ha na-agbajikwa nke ukwuu ma na-agbaji ngwa ngwa.Ha bụ ụdị inductor nke a na-ejikarị eme ihe, ebe ọ bụ na enwere ike ịchịkwa ikike nke ọma site na ịchịkwa oke nke ferrite na epoxy na ngwakọta.
Inductor na usoro na Ndekota
Inductor ejikọrọ n'usoro na ihe yiri ya na-akpa àgwà n'ụzọ dị iche na capacitors.
Dịka ọmụmaatụ, iji gbakọọ inductance nke otu inductors n'usoro, ị nwere ike chịkọta ụkpụrụ nke onye inductances n'otu n'otu.
L = L1 + L2 + … + Ln
Ebe L bụ mkpokọta inductance na L1, L2…Ln bụ onye inductances n'otu n'otu.
Were ya na ị nwere inductors abụọ, otu na-atụ 10uH na nke ọzọ 15uH, mgbe ahụ site na itinye ha n'usoro ị ga-enweta ngụkọta inductance nke 25uH.
Inductors n'otu n'otu na-akpa àgwà n'otu ụzọ ahụ dị ka resistors n'otu aka ahụ, a na-enye inductance site na:
1/L = 1/L1 + 1/L2 + … + 1/Ln
Ebe L bụ mkpokọta inductance na L1, L2…Ln bụ onye inductances n'otu n'otu.
N'ụzọ dị otú a, ọ bụrụ na ị jikọọ abụọ 10uH inductors n'otu aka ahụ, ị ​​ga-ejedebe na inductance nke 5uH.
