Hello every one
I am still studying a PSFB 48V to 350V 1kW.
Despite all my researches, there is something I am still unable to understand : how to choose the transformer's magnetizing inductance ?
In the UCC28951 documentation, page 42, TI gives the minimum condition to stay in CCM operating. But what about the maximum value ?
I have unfortunately built a transformer with a much bigger magnetizing inductance than this minimum (~200µH vs 15µH). Will this trouble the current mode control ? I don't find any documentation about this
Thank you for your help !
