Abstract

A charger may determine a type of power source to couple to the charger, and to adjust power from the power source based on the determined type of the power source.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a charger to determine a type of power source to couple to the charger, and to adjust power from the power source by the charger to change an impedance of the power based on the determined type of power source, wherein the charger to determine a specific first one of a plurality of modes of the charger based on power demand, and the charger to determine a specific second one of the plurality of modes of the charger based on a status of battery charging, wherein the specific first one of the modes is a voltage regulator mode.

2. The electronic apparatus of claim 1 , wherein the charger to perform power processing of the power based on the determined type of power source.

3. The electronic apparatus of claim 1 , wherein the plurality of modes of the charger include a maximum power point tracking (MPPT) mode, a maximum constant current tracking (MCCT) mode and the voltage regulator mode.

4. The electronic apparatus of claim 1 , wherein the type of power source is a direct current (DC) power source or an alternative power source.

5. The electronic apparatus of claim 4 , wherein the alternative power source is one of a solar power source, a mechanical power source, a photovoltaic power source, a thermal power source, a radio frequency power source, a vibration power source, biomechanical power source or a fuel cell.

6. An electronic apparatus comprising:
logic, at least a portion of which is hardware, to determine a type of power source, and to adjust power from the power source by the logic to change an impedance of the power based on the determined type of power source, wherein the logic to determine a specific first one of a plurality of modes based on power demand, and the charger to determine a specific second one of the plurality of modes based on a status of battery charging, wherein the specific first one of the modes is a voltage regulator mode.

7. The electronic apparatus of claim 6 , wherein the logic to perform power processing of the power based on the determined type of power source.

8. The electronic apparatus of claim 6 , wherein the type of power source is a direct current (DC) power source or an alternative power source.

9. A machine-readable medium comprising one or more instructions that when executed cause a device to perform one or more operations to:
determine a type of power source,
adjust power from the power source by change of an impedance of the power based on the determined type of power source;
determine a specific first one of a plurality of modes based on power demand; and
determine a specific second one of the plurality of modes based on a status of battery charging, wherein the specific first one of the modes is a voltage regulator mode.

10. The machine-readable medium of claim 9 , wherein the one or more instructions to adjust power by performing power processing of the power based on the determined type of power source.

11. The machine-readable medium of claim 9 , wherein the specific second one of the modes is a maximum constant current tracking (MCCT) mode.

12. The electronic apparatus of claim 1 , wherein the specific second one of the modes is a maximum constant current tracking (MCCT) mode.

13. The electronic apparatus of claim 6 , wherein the specific second one of the modes is a maximum constant current tracking (MCCT) mode and a voltage regulator mode.
