the best option read the book power supply cookbook by marti brown.
this book uploaded at:
in this book a sequentional topic for design the flyback power supply are presented.
but for brife:
Ipk=5.5Pout/Vinmin
Lpri=0.5Vin/Ipk*f
lg=(0.4*pi*Lpri*Ipk^2*10^8)/Ae*Bmax^2
where Ae in cm^2 and Bmax in Guose
Npri=Bmax*lg/0.4*pi*Ipk
hello, is there anybody still talking about this subject? I'm confused about this equation in the book metioned above and the primary words are like this:
the largest average current in primary side is Iav-max=(Dmax*Pout)/(n*Vinmin)
nominal peak current Ipk=5.5*Pout/Vinmin
I want to know how can this '5.5' be calculated.
Please someone help. Appreciate for it.
