Computer-assisted modeling of the phase-modulated full bridge converter

The small-signal dynamics of the phase-shifted full bridge DC/DC power converter is described with the aid of the computer program FREDOMSIM. The inherent inner feedback loop is open and the circuit is modeled as the connection of a snubbered full bridge with an output low pass filter, providing a third order system. The procedure looks suitable for modeling other switching topologies, mainly those proposing particular difficulties to their analysis.<
