Hi Mike,

is there any application notes/articles covering the detailed mathematical derivation of the PSFB  converter topology.

can you please share.

Thanks

    Hello,

    I searched ti.com and could not find a paper on derivations of the equations for a phase shifted full bridge (PSFB).  You might be able to find this in power supply design text books.  I did find some technical material you will find useful in regards to the operation of PSFB and the design of PSFB..

    I found this presentation on ti.com that goes through the operation of a PSFB and how it works.  https://www.ti.com/video/5045319944001

    The following link will bring you to an application note that goes through the step by step design process of a PSFB using the UCC28950/1.  It has all of the equations that are needed to design a PSFB. There is also a link to an excel design file in the application note that goes with it.  It uses the same equations as the application note.
