  • Patent number: 8022571
    Abstract: This is directed to methods, systems, and apparatuses for implementing circuitry that can be used to control multiple solar cells to generate power for a portable electronic device. For example, in response to determining that one or more of the solar cells is generating a reduce voltage output (e.g., due to a partial obstruction of one or more of the solar cells), the connections among the solar cells can be configured to generate a constant preset voltage, as long as a subset of the solar cells is operating. The voltage generated by the solar cells can then be boosted to a value suitable for powering the portable electronic device and/or any of its individual components. As another example, the connections among the solar cells can be configured to generate a startup voltage to directly power the portable electronic device and/or any of its components.

  • Patent number: 8013473
    Abstract: Methods and apparatus provide multiple input voltage regulation in which one regulator is selected for operation based on input power conditions. In one example, a dual input voltage regulator system in a combination smart card selects between contact and contactless (e.g., RF) operation based on which power source provides the highest available voltage level. A single transistor drop architecture provides low drop-out voltage regulation capability without substantially increased transistor size. In some implementations, multiplexed control of the regulators for each of a number independent power source inputs may be arranged to substantially reduce or prevent reverse current flow through regulators connected to inactive power inputs.

  • Patent number: 8013472
    Abstract: A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.
