SANHE Ferrite Core High Frequency EFD20 SMPS Flyback Transformers
Kune maviri akakosha marudzi eDC anoshandura, anoti, DC-DC inoshandura iyo inobuda voltage inodzorwa uye "DC transformer" iyo inobuda voltage inogadziriswa neinopinza.
Zvinodiwa zvakakosha:
(1) Ziva kutsaurwa kwemagetsi ekuisa nekubuda kwemagetsi uye hukama hwakaenzana pakati pekupinda nekubuda, uye unogona kuona kuburitsa kwakawanda;
(2) Shandisa transformer leakage inductance yekufambisa simba, hapana mashandisirwo emagetsi, shanduko inoshanda ye1, uye yakakwirira simba density;
(3) Iyo inobuda haidi sefa inductance, iyo inogona kuderedza zvakanyanya huwandu uye huremu hweinobuda sefa, iine yakanaka kuita kwesimba uye nekukurumidza kwechinguvana mhinduro;
(4) Iyo system frequency bandwidth inogona kufambisa voltage pasina kukanganisa;
(5) Vhura loop control inogamuchirwa, dunhu rekutonga riri nyore, zviri nyore kuona kunyorova switch, uye frequency yekuchinja inogona kuvandudzwa;
(6) Kuvimbika kwepamusoro, kukanganiswa kwemagetsi kudiki kune magetsi uye zvigadzirwa zvemagetsi.
