摘要： This voltage conversion circuit is provided with: a plurality of primary capacitors, which are charged with power supplied from a power supply; a secondary capacitor, which is connected in parallel to each of the primary capacitors, and which can be charged with a voltage to be supplied to a load circuit; and a plurality of switching circuits, which are provided corresponding to respective the primary capacitors, and which switch states of connections between the primary capacitors and the secondary capacitor. Furthermore, for the purpose of maintaining efficiency of power supply from the power supply to the primary capacitor side at a predetermined efficiency, the states of the connections between the power supply and the primary capacitors are adjusted such that at least some of the primary capacitors among the primary capacitors are in a serially connected state with respect to the power supply. Consequently, voltage conversion efficiency at the time of dropping an output voltage of a power supply circuit to a voltage to be supplied to the load circuit is brought into a best possible state.

摘要： The embodiments discussed herein relate to systems, methods, and apparatus for providing a charger (400) capable of adaptively handling a range of power inputs. The charger (400) can selectively activate different control switches (402, 404, 408, 412, 414, 416) 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 (402, 404, 408) 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 (402, 404, 408, 412, 414, 4169 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.
