Hi guys,

I am just learning how to design a forward converter power supply. I need to estimate the magnetic flux density of the transformer. But I am not able to get very useful information from the web site. As far as I know, a forward converter's magnetizing inductance is very high, and there is no air-gap. Therefore, the flux density should not be dependent on the Lxdi/dt equation, but instead should depend on the output current times the turns ratio, correct? But if I calculate it this way, the flux density will be very high. Also, what is recommended for the B-H curve of the forward converter? Is it true that I should scale down the size of the core and allow it to operate in the saturated regions of the B-H curve?
