Dual-Active-Bridge (DAB) converter is one of the most proposed topologies when considering DC/DC bidirectional isolated power conversion. In these applications, the power density of the converter is one of the main optimization goals. To improve power density, interleaved Input-Parallel Output-Parallel (IPOP) DAB configurations are analyzed in this paper. This configuration helps to reduce voltage and current ripple in input and output capacitors, whose contribution in the converter volume and weight is critical in aircraft applications. To this aim, an analytical model to determine the voltage and current waveforms in these components is proposed in this work. These equations are validated through a simulation model developed in PLECS. Finally, a comparison is presented to find the optimal IPOP configuration in a More Electric Aircraft case study. [-]
