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.

Abstract: The present invention discloses devices and methods for adaptive fast-charging of mobile devices. Methods include the steps of: firstly determining whether a first connected component is charged; upon firstly determining the first connected component isn't charged, secondly determining whether the first connected component is adapted for rapid charging; and upon secondly determining the first connected component is adapted for rapid charging, firstly charging the first connected component at a high charging rate via a charging device. Preferably, the charging device is selected from the group consisting of: a rapid charger and a slave battery. Preferably, the first connected component is selected from the group consisting of: a mobile device and a slave battery. Preferably, the high charging rate is selected from the group consisting of: greater than about 4 C, greater than about 5 C, greater than about 10 C, greater than about 20 C, greater than about 30 C, and greater than about 60 C.
