Claim Text:
1. A power supply system for providing power to an information processing system, the information processing system being electrically coupled to an AC power source and comprising at least one computer unit, the power supply system comprising: at least one AC power supply unit electrically coupled to the at least one computer unit and the AC power, respectively; at least one DC power supply unit electrically coupled to the at least one computer unit; and a backup power unit electrically coupled to the at least one DC power supply unit, wherein, in response to the at least one AC power supply unit not supplying power, the at least one DC power supply unit automatically supplies power to the at least one computer unit; and wherein the at least one computer unit comprises a system administration module, the at least one AC power supply unit comprises an AC power supply unit microcontroller, and the DC power supply unit comprises a DC power supply unit microcontroller, wherein the system administration module is electrically coupled to the AC power supply unit microcontroller and the DC power supply unit microcontroller via a communication bus to thereby control one of the at least one AC power supply unit and the DC power supply unit to supply power to the at least one computer unit; and wherein the at least one AC power supply unit comprises a first switching module, wherein the at least one DC power supply unit comprises a second switching module and a DC power supply unit output control module, wherein an output of the first switching module is electrically coupled to an input of the second switching module, wherein an output of the second switching module is electrically coupled to an input of the DC power supply unit output control module, wherein, in response to the at least one AC power supply unit not supplying power, the first switching module sends an enabling signal for enabling the second switching module and thereby enabling the DC power supply unit output control module to control the at least one DC power supply unit to supply power to the at least one computer unit.
