Voltage gain curves in six modes. Drawn by Mingde& Cheng
  • For charging the deeply depleted battery, a wide voltage gain dc/dc converter based on LLC was proposed;
  • LLC resonant converter is suitable for battery charging applications, but it has a wide voltage gain range and large conversion loss under traditional design;
  • This topology uses H5 reconfigurable bridge to realize six reconfigurable modes charging.

H5-bridge Family Series Resonant Converters for PEV Charging Applications
Abstract: Plug-in electric vehicles’ charger is preferred to cover an ultrawide battery voltage range with the vehicle-to-grid capability. Conventional bidirectional resonant dc–dc converters suffer from the contradiction among wide voltage gain range, squeezed dc-link voltage span, and narrow switching frequency band.
