Abstract

In this paper, an improved power flow model for dual active bridge (DAB) converters with phase-shift modulation is introduced. Based on the analysis and the accordingly derived equations, a power plateau phenomenon, in which the phase shift loses its power-regulating capability, is investigated. Moreover, it is found that this power plateau phenomenon leads to an inversed power flow characteristic in some specific regions compared to the models reported in previous literature. The characteristics of the power plateau and its occurring conditions are derived and analyzed in depth. The calculations, simulations and analyses have been verified by experiments.
