Abstract
An Uninterrupted Power Supply (UPS) power supply system is provided, which includes: a filter module connected to a mains supply and configured to filter an input from the mains supply; a BOOST module, where a first terminal of the BOOST module is connected to the filter module via a first switch group and connected to a battery via a second switch group, and a second terminal of the BOOST module is connected to a positive bus and a negative bus; and a bi-directional Direct Current/Direct Current (DC/DC) module, where a first terminal of the bi-directional DC/DC module is connected to the battery, and a second terminal of the bi-directional DC/DC module is connected to the positive bus and the negative bus.

An Uninterrupted Power Supply (UPS) power supply system, comprising:
- a filter module connected to a mains supply and configured to filter an input from the mains supply;
- a BOOST module, wherein a first terminal of the BOOST module is connected to the filter module via a first switch group and connected to a battery via a second switch group, and a second terminal of the BOOST module is connected to a positive bus and a negative bus;
- and
- a bi-directional Direct Current/Direct Current (DC/DC) module, wherein a first terminal of the bi-directional DC/DC module is connected to the battery, and a second terminal of the bi-directional DC/DC module is connected to the positive bus and the negative bus,
- wherein in a battery supply mode, in a case that an output power is smaller than a first power, only the bi-directional DC/DC module discharges;
- in a case that the output power is greater than the first power and smaller than a second power, only the BOOST module discharges;
- and in a case that the output power is greater than the second power, the bi-directional DC/DC module and the BOOST module both discharge.
