| Abstract: | The operation principle of the phase-shift-controlled double-full-bridge power electronic transformer is analyzed, and, by the analysis of the state space model, an equivalent transformer model and its corresponding output characteristic curve are obtained. Moreover, the expressions of both the equivalent transfer ratio and the inner resistance are deduced. Thus, it is proved that in terms of the essential features of the proposed model, the conventional transformer can be replaced and extended by the power electronic transformer. The correctness of the theoretical analyses is finally verified by simulated exoeriments. |
