[0024] It should be understood that the foregoing general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0025] The accompanying drawings, which are incorporated into and form part of the specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure and do not limit the present disclosure.

[0026] Figure 1 A structural schematic diagram of the UPS device provided by the present disclosure is shown. DETAILED DESCRIPTION

[0027] The exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to help understanding, and should be considered as merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Also, in order to be clear and concise, the description below omits the description of well-known functions and structures.

[0028] The existing uninterruptible power system (UPS) is powered by the mains power grid 101 (AC power). When the mains power grid 101 is normal, the UPS uses the mains power grid 101 to provide AC power to the load 103, while converting the AC power provided by the mains power grid 101 into DC power and storing it in the energy storage battery 104. When the mains power grid 101 fails, the UPS uses an inverter to convert the DC power output from the energy storage battery 104 into AC power to supply power to the load 103, thereby achieving power continuity for the load 103.

[0029] In related technologies, since the DC power source of the energy storage battery 104 can only be provided by the mains power grid 101, if the mains power grid 101 fails for a long period of time, it will be unable to store energy for the energy storage battery 104, and the UPS function will not be realized.

When the mains power is normal, the bidirectional inverter 102 supplies power to the load 103 through the AC power output terminal and converts the AC power input from the mains power into DC power, which is then stored in the energy storage battery 104 through the charging / discharging terminal. When the mains power fails, the bidirectional inverter 102 converts the DC power input to the bidirectional inverter 102 through the charging / discharging terminal of the energy storage battery 104 into AC power and supplies power to the load 103 through the AC power output terminal.
