摘要： The present invention relates to an information processing apparatus that comprises a plurality of electric circuits and that has power supply lines for the individual electric circuits. It provides a switching regulator that controls the power that is supplied by an external power source to such an information processing apparatus, while inhibiting power waste, and the information processing apparatus and a method for its control.
The information processing apparatus, which is activated by power supplied from an external power source, comprises: a first power supply line for supplying power to a first electric circuitry; a second power supply line for supplying power to a second electric circuitry; a i-th power supply line for supplying power to a i-th electric circuitry (i is an integer of 1 ≦ i ≦ n, and n is an integer equal to 2 or greater); means for monitoring a first voltage of the first power supply line; means for monitoring a second voltage of the second power supply line; means for monitoring a i-th voltage of the i-th power supply line; means for selecting the minimum voltage among the first through the i-th voltages; means for comparing the minimum voltage with a previously given reference voltage; and connecting/disconnecting means for starting or halting the power supply from the external power source in response to the comparison result. As the lowest voltage can be used as a feedback target, the application of a high voltage is not required even if the safety of the system is taken into consideration and power will not be wasted.

摘要： The present invention discloses a battery charger that can be connected in series to a power feed line, which lies between an external power source and an electric/electronic device, and that monitors the power consumption state of the electric/electronic device and begins and halts the charging of a battery in consonance with the power consumption state. Since a battery charger according to the present invention can be inserted in series into a power feed line that lies between an AC/DC adaptor and an electric/electronic device, the wiring arrangement is not complicated and a spare battery can be automatically charged. Since the charging is performed only during a period in which power consumption by the electric/electronic device is relatively low, the charging operation does not affect the system operation. As the battery charger does not require AC to DC conversion circuit, it is compact and light and is suitable for use along with a portable device. Further, when the spare battery pack is carried with being attached into the battery charger, the volume is not great, and as the terminal portions of the battery are covered and are protected from coming into contact with foreign conductive material, the possibility that the electrodes of the battery will be short-circuited can be prevented. To use a notebook computer while staying at a hotel on a business trip, a user need merely connect in series an AC/DC adaptor, a Travel Quick Charger, and a notebook computer in the named order via a power supply cord. The spare battery can be attached into a Travel Quick Charger while being carried to the destination.

摘要： To make it possible to supply to a battery a charging current having a sufficient capacity which enables a short-time charge while supplying a drive current for usual operation to a battery operable electronic device, without making construction large-sized and complicated. The present invention is intended to be able to delicately vary a charging current of a battery according to the variation of power consumption of load on an electronic device, by providing constant power feedback control means for performing feedback control of the output power so as to cause a constant power or a nearly constant power, based on a current feedback value and a voltage feedback value.
