This paper presents a new standby structure where a forward converter is integrated with a dc–dc phase-shift full-bridge (PSFB) converter for server power supplies. While a typical standby structure consists of an independent flyback converter, the proposed standby structure is integrated with one leg of the dc–dc PSFB converter. Its main advantages are that the voltage across a standby switch is...
This paper presents high-efficiency standby forward converter integrated with the DC/DC Phase-Shift Full Bridge (PSFB) converter. By sharing one leg of DC/DC PSFB converter, the proposed converter features low-voltage stress, no snubber and zero-voltage switching (ZVS) over the entire load range. Thus, the proposed converter has high-efficiency, especially under half load condition. Furthermore, by...
