Unified high power and low power battery charger |
摘要 |
The embodiments discussed herein relate to systems, methods, and apparatus for providing a charger capable of adaptively handling a range of power inputs. The charger can selectively activate different control switches within the charger in order to more efficiently use current supplied to the charger. When a low power input is provided to the charger, the charger can reduce the number of active control switches being used to provide a voltage output from the charger. In this way, the capacitance required to toggle the control switches can be reduced. When a high power input is provided to the charger, the number of active control switches can be increased in order to increase a total amount of charge that can be provided from the charger, thereby reducing charge times for batteries. |

1. A machine-readable non-transitory storage medium storing instructions that, when executed by a processor included in a computing device, cause the computing device to carry out steps that include:
exclusively activating, based on an input provided by a power supply, one of a first switch group and a second switch group included in a charger, wherein the second switch group has a greater capacitance than the first switch group; and periodically toggling, based on the activating, one or more switches of either the first switch group or the second switch group causing a voltage output from the charger. |
