Conclusions

A PSFB is a good candidate for applications that require a wide input/output voltage range and a fast load transient response. In this paper, we discussed PSFB fundamentals including operational principles, types of rectifiers, rectifier clamping options, modes of controls, synchronous rectifier operational modes, control modes and light-load management schemes.
