  • Patent number: 9559538
    Abstract: Various embodiments of the invention relate to a battery charging system that enhances the charge rate and reduces the charge time for a battery applied in a mobile device. The battery charging system is provided with an adapter output voltage, and generates a battery charging current to drive the battery. This adapter output voltage is controlled to vary within a reference voltage range which is narrowly controlled to include and track a preferred adapter voltage. The battery is therefore driven by the battery charging current that is associated with a preferred charging current under a preferred charging condition. The battery charging process may be completed under a condition that is substantially close to the preferred charging condition, allowing an enhanced battery charge rate and a reduced battery charge time.

  • Publication number: 20070052395
    Abstract: During burst mode operation of a four switch buck-boost converter, the input voltage and an output voltage can be detected and a preset peak charging current threshold level can be modulated when the difference between the input voltage and output voltage is within a prescribed range. A burst mode charging cycle will progress until the modulated peak charging threshold level is attained and cut off at the set peak level. A charge transfer cycle and discharge cycle may proceed thereafter.
