The following four popular topologies were considered for analysis. Based on this study, the dual-active bridge was chosen for implementation in this reference design, owing to the ease of bidirectional operation, modular structure, competitive efficiency, and power density numbers with respect to other competing topologies.
The maximum power transfer in a dual-active bridge occurs at a phase shift of 90°. However, a high phase shift requires a high leakage inductance for power transfer. Using a high inductor leads to increased RMS currents in the primary and secondary side, which affects the efficiency of the converter.
