Hello everyone,
I am desiging with a Push pull topology a 500W DC-DC converter (Vin=24V +- 10%, Vout=200 V at 100 kHz).
The calculations gave me that I can use a relationship n=Np/Ns=1/12 with a EPCOS-TDK E core 55/28/21 (https://en.tdk.eu/inf/80/db/fer/e_55_28_21.pdf) that has an AL=6400nH, where:
Imag=Vinmin*Dmax/(L_mag*fsw)=26.04A,
and
Iinmax=Po/Vinmin=23.15A.
Is it ok that Imag>Iin? What do you think? What can you guys suggest me?
I am willing to use these Mosfets (FDH038AN08A1, https://www.mouser.com/ds/2/149/FDH038AN08A1-103477.pdf), and of course, every switch will have its own snubber network.
Thank you for your help. Have a nice day.
David.
