Formulation of the energy-storage factor for isolated power convertors using integrated magnetics

The energy storage in energy-storage components is examined for isolated power convertors. In addition to the basic convertors such as the flyback and forward, the paper also develops the analysis for the various isolated versions of power convertors as well as convertors with integrated magnetics. It is interesting to study the variation of energy-storage factor so that their capability for energy storage can be examined. The factor can therefore give an equivalence of the AC power factor for the DC circuit.
