| Abstract: | A circuit averaged model for ZVS phase-shifted full bridge converter is introduced. The model can be easily implemented in circuit analysis program such as Simetrix to derive small-signal characteristics as well as predict large-signal transient behaviors of the converter. Using the averaged approach, the required computer time is drastically reduced. Simulation results illustrating both small and large signal behaviors of the converter are presented. |
