Problems solved by technology

[0002] As far as the power supply is concerned, once a momentary power failure occurs during the operation of electronic equipment such as personal computers and servers that use commercial power (alternating current), errors will occur in the operation itself, resulting in adverse results such as loss of valuable processing data.

Embodiment Construction

[0024] Next, an uninterruptible power supply device according to an embodiment of the present invention will be described with reference to the drawings.

[0025] This uninterruptible power supply device is a commercial power supply (alternating current) power source. For example, it is installed in electronic equipment such as personal computers, and it is a device that has a good effect on ensuring the operation of the main body of the electronic equipment when the above-mentioned commercial power supply fails; secondary batteries such as Li-ion batteries and Ni-MH batteries are equipped. Specifically, the uninterruptible power supply device is connected to the power supply device in the electronic equipment for use. Moreover, the uninterruptible power supply device also has the function of receiving the direct current generated by the above power supply device to charge the secondary battery, and at the same time when the commercial power supply (alternating current) is out...

Abstract

An uninterruptible power supply comprises a rechargeable battery, such as a Li-ion battery and a Ni-MH battery, and is suitable for installation in electronic apparatus, such as a personal computer. The uninterruptible power supply appraises an operating state of a main body of the electronic apparatus on the basis of an output state of first DC power (standby power) necessary for standby operation of the main body and second DC power (operating power) necessary for normal operation of the main body, that are produced by a power supply unit, or on the basis of a power loading dose of the power supply unit, and supplies backup power to the main body only when the main body is in normal operation.

Description

technical field [0001] The invention relates to an uninterruptible power supply device with good applicability, which is installed in computers and other electronic equipment and can be used as a backup power supply when the AC power fails. Background technique [0002] In terms of power supply, once a momentary power failure occurs during the operation of electronic equipment such as personal computers and servers that use commercial power (alternating current), errors will occur in the operation itself, resulting in the loss of valuable processing data and other undesirable results. Therefore, this technology installs an uninterruptible power supply device (battery box) mainly composed of a secondary battery in this type of electronic equipment, so as to compensate for the operation of the electronic equipment when the commercial power supply is out of power, and protect its processing data. Various attempts have been made on the issue of functionality (for example, refer ...
