求EFD20变压器设计

2UEWø0.25 99Ts    1.5mH
TLW-Bø0.35 30Ts
2UEWø0.21 13Ts
试试看

呵呵,我也用EFD的喔,你骨架哪里买的?我买的好贵,可以告诉我吗?

Ae=29min,Ve=1460
Bmax=0.28
F=65KHZ.
DCM/CCM: 85%

PRI 2UEW D0.23mm*100Ts. Rpri=2.76 Ohm Ploss=0.173^2*2.76=0.08W
SEC TEX-e D0.3mm*40Ts. Psec=0.663 Ohm Plose=0.42^2*0.663=0.12W
Aux 2UEW D0.2mm*17Ts.
Core Loss=0.29W
Total Lose=0.08+0.12+0.29=0.49W.
預估變壓器溫度 85DegreeC at ambient 25DegreeC.

難道此變壓器無需告訴工作在什麼電路形式中也能設計?
