N2 - This manuscript provides a detailed analysis of an asymmetrical bidirectional DC/DC converter operating across multiple regions. The converter features a partially scaled diode bridge and a partially scaled active bridge, connected in parallel on the secondary side, effectively integrating single- and dual-active-bridge topologies. A novel modulation technique enables active power-sharing control between the parallel-connected bridges, addressing challenges related to magnetic tolerances and asymmetrical power demands. By extending the approach beyond the discontinuous conduction mode, this study examines new boundary conditions-hybrid 1, hybrid 2, and continuous conduction mode-along with power transfer formulations for different operating regions.
