Abstract
The present invention discloses an uninterrupted power bank, mainly comprising: a first switch, a rectifier, a first power converter, a second switch, a battery unit, a second power converter, a third power converter, a third switch, a fourth switch, and output ports. During a normal supply of a mains supply, an AC power provided by the mains supply is transmitted from the uninterrupted power bank to a back-end power supply device. In the meantime, the AC power is simultaneously converted to a DC power and then stored in the battery unit. When the mains supply is suddenly interrupted, the DC power stored in the battery unit is released and subsequently converted to a 390 VDC power for being supplied to the power supply device. Therefore, this uninterrupted power bank is able to largely reduce the power loss because of supplying DC power to back-end power supply device.
