SANHE Ferrite Core High Frequency EFD20 SMPS Flyback Transformers
Kukho iindidi ezimbini ezisisiseko zeenguqu ze-DC, ezizezi, isiguquli se-DC-DC esinombane ophumayo olawulwayo kunye ne-"DC transformer" ombane wayo ophumayo ulungelelaniswa kunye negalelo.
Iimfuno ezisisiseko:
(1) Ukuqonda ukwahlulwa kombane wegalelo kunye nemveliso yombane kunye nobudlelwane obulinganayo phakathi kwegalelo kunye nemveliso, kwaye inokuqonda imveliso emininzi;
(2) Sebenzisa i-transformer leakage inductance yokuhanjiswa kwamandla, akukho kusetyenziswa kwamandla, ukusebenza kakuhle kokuguqulwa kwe-1, kunye nokuxinana kwamandla aphezulu;
(3) Imveliso ayifuni i-filter inductance, enokunciphisa kakhulu umthamo kunye nobunzima bokucoca imveliso, kunye nokusebenza kakuhle okuguquguqukayo kunye nokuphendula ngokukhawuleza okwethutyana;
(4) Inkqubo ye-frequency bandwidth inokuhambisa i-voltage ngaphandle kokuphazamiseka;
(5) Ulawulo lwe-loop oluvulekile luyamkelwa, isiphaluka solawulo silula, kulula ukuqonda ukutshintshela okuthambileyo, kunye nokutshintshwa kwefrikhwensi kunokuphuculwa ngakumbi;
(6) Ukuthembeka okuphezulu, ukuphazamiseka okuncinci kwe-electromagnetic kubonelelo lwamandla kunye nezixhobo zombane.
