Abstract:
1. A backup-type power supply system, comprising: a power output integration unit; at least one first power supply module which outputs first power at a first potential and includes at least N+1 power supply devices connecting to the power output integration unit and a first power balance unit electrically connecting to the N+1 power supply devices, the first power balance unit providing a first loading power balance mode to make the N+1 power supply devices to become a first backup-type module; and at least one second power supply module which outputs second power at a second potential different from the first potential and includes at least N+1 power supply devices connecting to the power output integration unit and a second power balance unit electrically connecting to the N+1 power supply devices, the second power balance unit providing a second loading power balance mode to make the N+1 power supply devices to become a second backup-type mode.
