This letter presents a reconfigurable dual LLC converter based on a five-switch bridge to charge the deeply depleted PEV onboard battery packs. Due to the reconfiguration of the primary-side switch network, two resonant tanks could operate in integrated half-bridge, half-bridge, hybrid bridge, and full-bridge modes. Thus, four operation modes are derived, with their normalized voltage gains scaled to 1:2:3:4, respectively. Those four modes enable a squeezed switching frequency span, which is close to the resonant frequency. Therefore, the efficiency performance over an ultra-wide output voltage range can be optimized. Zero-voltage-switching can be realized in all power MOSFETs over the entire load range. The operating principles, voltage gains analysis are briefed. A 1.1 kW-rated prototype converting 390V input to 100V-420V output, is designed and tested to validate the proof of concept. 97.64% peak efficiency and good efficiency over the full charging range is reported.
