I-SANHE Ferrite Core High Frequency EFD20 SMPS Flyback Transformers
Kunezinhlobo ezimbili eziyisisekelo zama-DC transformer, okungukuthi, isiguquli se-DC-DC esinogesi ophumayo olawulwayo kanye ne-"DC transformer" ogesi wayo ophumayo ulungiswa nokokufaka.
Izidingo eziyisisekelo:
(1) Abone ukuhlukaniswa kukagesi we-voltage yokufaka nokukhiphayo kanye nobudlelwano obulinganayo phakathi kokungenayo nokuphumayo, futhi angathola okukhiphayo okuningi;
(2) Sebenzisa i-transformer leakage inductance yokudlulisa amandla, akukho ukusetshenziswa kwamandla, ukusebenza kahle kokuguqulwa kwe-1, kanye nokuminyana kwamandla aphezulu;
(3) Okukhiphayo akudingi i-inductance yesihlungi, enganciphisa kakhulu ivolumu nesisindo sesihlungi esiphumayo, ngokusebenza okuhle okuguquguqukayo nokusabela kwesikhashana okusheshayo;
(4) I-bandwidth yesistimu ingadlulisela i-voltage ngaphandle kokuhlanekezela;
(5) Ukulawulwa kwe-loop evulekile kwamukelwa, isifunda sokulawula silula, kulula ukubona ukushintshwa okuthambile, futhi imvamisa yokushintsha ingathuthukiswa ngokwengeziwe;
(6) Ukuthembeka okuphezulu, ukuphazamiseka okuncane kwe-electromagnetic ekunikezeni amandla kanye nemishini kagesi.
