Hi,
Just noticed the ISL6752 ZVS Full Bridge Controller promises to be everything that the PSFB is, but simpler (and therefore better). Page 1 says...
ISL6752
The PSFB is known to present a minefield of potential failure mechanisms for the unwary (eg during transients and startup) . And as the following thread shows, (latterly) the PSFB circuit common to most App Notes requires quite some "augmentation" to make it optimal...
Have we seen the end of the PSFB?

Phase Shift Full Bridge SMPS is massively over-hyped?
Hello, The Phase Shift Full Bridge (PSFB) converter is a hoax. –The LTspice simulation attached of a “plain” Full Bridge SMPS bears this out. PSFB claims to be able to reduce switching losses compared to the “plain” Full Bridge SMPS. However the PSFB does have Turn-OFF switching losses, just...
