FB SMPS or PSFB???

Hi all!

We are designing some 700W offline converter but we are not sure what should we choose: phase shift full bridge or plain full bridge? 

The PSFB no needs additional hardware and gives zero switch-on switching losses, so why doesn't everyone always do a PSFB?

Hold on one moment,

Because of the hard turn-on rellated switching losses.
