Phase-Shifted Full Bridge DC/DC Power Converter Design Guide Abstract The phase shifted full bridge (PSFB) converter is used for DC-DC conversion in various applications, for example in telecom systems to convert a high voltage bus to an intermediate distribution voltage, typically closer to 48V....
This chapter discusses phase-shifted full-bridge converter. The duty cycle of the main switches varies significantly depending on the input voltage level and the load demand in basic forward converters. Because of that, the Fourier harmonic contents of switching waveforms also change and produce an ...

Primary side scope waveforms (Figure 8) exhibit the very clean transitions typical with the phase-shifted full bridge. Since the LTC1922-1 is a current mode controller, it is easily adaptable to standard load-sharing techniques used in redundant power system applications. Additional fea...
The phase-shifted full-bridge zero-voltage-switching (PS-FB-ZVS) PWM converter is widely used in medium and high power levels.However,there are two problems existing in this kind of converter:one is that lagging leg has narrow zero-voltage-switching ranges,and the other is that the output ...
At the second stage a phase-shifted full-bridge with a current doubler rectifier is selected to ensure zero voltage switching and reduce the transformer secondary winding current. Moreover, an active power decoupling cell is employed in order to reduce dc-link capacitance and, consequently, ...
