SANHE Ferrite Core High zaus EFD20 SMPS Flyback Transformers
Muaj ob hom kev hloov pauv ntawm DC, uas yog, DC-DC converter uas nws cov zis hluav taws xob tau tswj hwm thiab "DC transformer" uas cov zis hluav taws xob tau hloov kho nrog cov tswv yim.
Cov kev cai yooj yim:
(1) Paub qhov hluav taws xob cais tawm ntawm cov tswv yim thiab cov zis hluav taws xob thiab cov kev sib raug zoo ntawm cov tswv yim thiab cov zis, thiab tuaj yeem paub ntau yam khoom siv;
(2) Siv transformer to inductance rau lub zog kis tau tus mob, tsis muaj zog noj, conversion efficiency ntawm 1, thiab siab zog ceev;
(3) Cov zis tsis xav tau lim inductance, uas tuaj yeem txo qhov ntim thiab qhov hnyav ntawm cov zis lim, nrog kev ua haujlwm zoo thiab cov lus teb ceev ceev;
(4) Lub kaw lus zaus bandwidth tuaj yeem xa hluav taws xob tsis muaj kev cuam tshuam;
(5) Qhib lub voj tswj tau txais yuav, kev tswj xyuas Circuit Court yog yooj yim, nws yog ib qho yooj yim kom paub txog kev hloov pauv, thiab qhov hloov zaus tuaj yeem txhim kho ntxiv;
(6) Muaj kev ntseeg siab, me me electromagnetic cuam tshuam rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
