Abstract: Chargers and methods are provided which increase the charging efficiency of the chargers by implementing voltage amplitude modulation (VAM) instead of voltage frequency modulation. The charging voltage amplitude is modulated using feedback from at least one energy storage device that is being charged by the charger, while maintaining a charging voltage frequency constant at a LLC resonance frequency of the charger. A buck/boost configuration may be used to reduce maximal voltage levels and further optimize the charger's design.
