Abstract

The present disclosure is an uninterruptible power supply (UPS) and a power supply system. The UPS includes a first switching module, a rectifier, a second switching module, a direct-current (DC) bus and a controller. A first end of the first switching module is connected to an alternating-current (AC) power supply, and a second end of the first switching module is connected to an input end of the rectifier. Two terminals at a first end of the second switching module are respectively connected to a positive electrode and a negative electrode of a battery pack, two terminals at a second end of the second switching module are respectively connected to the negative electrode and the positive electrode of the battery pack, and a third end of the second switching module is connected to the input end of the rectifier. An output end of the rectifier is connected to a DC bus.
