Problems solved by technology
[0002] The uninterruptible power supply generally includes the main power supply and the auxiliary power supply. The main power supply is generally an AC power supply, and the auxiliary power supply is a rechargeable battery. The rechargeable battery is charged. When the AC power fails to supply power, the rechargeable battery converts the DC voltage into an AC voltage through an inverter for power supply. In this way, the rectifier and inverter are used to convert the current during the conversion process. It consumes a certain amount of electric energy, which is not conducive to energy saving and low efficiency. In addition, when switching, power failure often occurs, and the rechargeable battery is in a charging state for a long time, with short life and low reliability.
