  "textContent": "An uninterruptible power supply is provided including: a primary branch, including a rectifier module and an inverter module; a battery branch, including a bidirectional power conversion module and a battery; and a controller, including a charge/discharge controller. The charge/discharge controller is configured to: when an increment of a load amount of the load is greater than a first preset threshold, control the bidirectional power conversion module to perform DC-DC conversion on a direct current output by the battery, so that the battery supplies power to the load to meet an increased power requirement of the load, thereby maintaining a stable output power of the alternating current power supply; and when a decrement of the load amount of the load is greater than a second preset threshold, control the bidirectional power conversion module to perform DC-DC conversion on a direct current that is output by the rectifier module and exceeds a power requirement of the load to charge the battery, thereby maintaining a stable output power of the alternating current power supply.",
