Flyback Transformer (Buck-boost converter)
Flyback transformers yog tsim rau cov khoom siv hluav taws xob qis thiab ntau lub zog hloov hluav taws xob.Txawm li cas los xij, qhov nyuaj tseem ceeb ntawm flyback transformers yog tus tsim.Lub input voltage ntau ntawm flyback transformer yog dav.Tshwj xeeb tshaj yog, thaum nyob rau hauv qis input voltage thiab tag nrho load tej yam kev mob, lub transformer yuav ua hauj lwm nyob rau hauv tas li tam sim no hom, thaum nyob rau hauv siab input voltage thiab lub teeb load tej yam kev mob, lub transformer yuav ua hauj lwm nyob rau hauv discontinuous tam sim no hom.
Cov ncauj lus kom ntxaws zoo yog qhia hauv qab no:
(1) Cov dej inductance tuaj yeem tswj tau li ntawm 1% -10% ntawm lub ntsiab inductance;
(2) Cov tub ntxhais hlau nplaum muaj qhov sib txuas zoo electromagnetic, cov qauv yooj yim thiab kev ua haujlwm siab;
(3) Kev ua haujlwm siab, siab zog ceev, zaus ntawm 50kHz ~ 300kHz.
(4) Cov yam ntxwv zoo ntawm cov cua sov dissipation, nrog rau qhov chaw siab tshaj plaws rau qhov sib piv, lub tshav kub luv luv, yooj yim rau cua sov dissipation.
(5) Kev ua haujlwm siab, cov qauv sib nqus ntawm cov duab geometric tshwj xeeb tuaj yeem txo cov tub ntxhais poob zoo.
(6) Me me hluav taws xob hluav taws xob cuam tshuam.Tsawg zog poob, tsis tshua muaj kub nce, efficiency siab.
(7) Lub Circuit Court yog yooj yim thiab muaj peev xwm ua tau zoo muab ntau yam DC tso zis, ua rau nws tsim nyog rau ntau pab pawg tso zis.
(8) Qhov piv ntawm transformer lem yog me me.
(9) Thaum cov input voltage fluctuates nyob rau hauv ib tug loj ntau yam, tseem yuav muaj ib tug kuj ruaj khov tso zis.
◆ Kev ntseeg siab, ua raws li AEC-Q200;
◆ poob qis;
◆ Tsawg leakage inductance;
◆ Kev khiav hauj lwm dav voltage thiab ntau zaus;
◆ Siab zog ceev, zoo cua sov dissipation;
◆ Kub Curie Kub;
◆ Yooj yim los ua ke
Haum rau kev tsav tsheb transformers, lub ntsiab transformers thiab tso zis lim inductors, PFC inductors, dav siv nyob rau hauv cov xim TV thiab LCD fais fab mov, computers, saib, keyboards, cathode-ray raj, SPMS, DC-DC fais fab mov hom kev kawm, roj teeb them, kev sib txuas lus, daim ntawv thov photovoltaic thiab lwm yam khoom siv hluav taws xob;
