ABSTRACT:
An expedient and simplified uninterrupted power-supplying apparatus is provided. Such apparatus includes a power-storing device for storing an electric signal in a first instance and releasing the electric signal in a second instance, an AC/DC converting device for converting an AC signal provided by the power source into a DC signal, a DC/DC converting device for receiving the DC signal, and generating the uninterrupted power and storing the electric signal in the power-storing device in response to a voltage thereof in the first instance, and receiving the released electric signal and generating the uninterrupted power in the second instance, and a controlling device for controlling the DC/DC converting device to store the electric signal in the power-storing device and making the AC/DC converting device vary the DC signal in response to the voltage of the power-storing device. The invention also discloses a method for supplying an uninterrupted power.
