Embodiment Construction

[0026] Figure 1a to Figure 1d Circuits 2100-2400 are described respectively, where a power supply is connected in series with a capacitor to supply power to a load, and the voltage is the sum of the voltages output by the power supply and capacitor. In each circuit 2100-2400, depending on how much current the load is trying to draw from the combination of the power source and the capacitor, the power converter selectively charges the capacitor or cooperates with the capacitor to limit the current drawn from the power source. In each of the circuits 2100-2400, the power source may be a battery, a power source providing a DC output from an AC main, a power feed provided from an external device (for example, except digital serial communication from an electronic device such as a computer) external cables carrying power), or any of various other types of power sources. Furthermore, the capacitor may be any of various types of capacitive elements including supercapacitors or ultr...

Abstract

A circuit to supply power to a load incorporates a first power source, a second power source that may be detachable, a power converter and at least one capacitor (capacitive element), where the first power source is capable of powering the load when charged, where the second power source is not capable of powering the load, but the second power source is capable of trickle-charging the first power source at a time when the first power source is not powering the load, where the power converter may impose a limit on a flow of current through the power converter, and where the at least one capacitor may cooperate to temporarily support a flow of additional current that circumvents the power converter at a time when the load attempts to draw a relatively greater amount of current.

Description

technical field [0001] This specification relates to trickle charging and the operation of power converters to store and efficiently use power supplied from a limited source. Background technique [0002] Users of various electrical devices often find themselves in situations where power is available but the capacity of that power is limited. Examples of this are the 12-volt auxiliary power socket in a car and the Universal Serial Bus (USB) port of a computer, which can supply 12-volt DC and 5-volt DC, respectively, but their current capacity is very limited, which limits The types of electrical devices they can power, thereby limiting their usefulness. Contents of the invention [0003] A circuit for supplying power to a load combining a first power source, a second power source which may be removable, a power converter and at least one capacitor (capacitive element), wherein the first power source is capable of powering the load after being charged, wherein The second ...
