CHARGER AND ELECTRONIC APPARATUS STABLY SUPPLYING OPERATING VOLTAGE
First Claim
1. A charger comprising:
- a power obtaining unit which charges a first power storage device with a voltage supplied from outside; and
a power transfer unit which transfers power stored in the first power storage device to a second power storage device having a capacitance larger than the first power storage device so as to store the power in the second power storage device, whereinthe power transfer unit includes a voltage decrease reduction unit which reduces voltage decrease of the first power storage device per transfer of the power from the first power storage device to the second power storage device.

Abstract
A charger includes a power obtaining unit and a power transfer unit. The power obtaining unit charges a first power storage device with a voltage supplied from outside. The power transfer unit transfers power stored in the first power storage device to a second power storage device so as to store the power in the second power storage device. The power transfer unit includes a voltage decrease reduction unit. The voltage decrease reduction unit reduces voltage decrease of the first power storage device per transfer of the power from the first power storage device to the second power storage device. The second power storage device has a capacitance larger than the first power storage device.

16. A charging method comprising:
-
a power obtaining step of charging a first power storage device with a voltage supplied from outside; and a power transfer step of transferring power stored in the first power storage device to a second power storage device having a capacitance larger than the first power storage device so as to store the power in the second power storage device, wherein the power transfer step includes a voltage decrease reduction step of reducing voltage decrease of the first power storage device per transfer of the power from the first power storage device to the second power storage device. - View Dependent Claims (17, 18, 19)
