In wide voltage range applications such as vehicle-to-grid enabled onboard charging, conventional frequency modulated bidirectional CLLC topology has its intrinsic limitations. Its frequency span is extremely wide and the soft switching feature might get lost. To cope with this issue, this paper proposes a novel reconfigurable bidirectional CLLC derived resonant topology. The reconfiguration of half-bridge and full-bridge is enabled on both the primary and secondary sides to extend its voltage gain range. Pulse width and frequency hybrid modulation is adopted to narrow down its switching frequency span. The operating principles, circuit modeling, and the design methodology are presented in detail. A simulation model of 1 kW rated converter is built to realize an efficient power conversion between 400 V dc bus and 100-440 Vdc battery pack. The simulation results validate the effectiveness of the proposed topology and modulation method.
