POWER-SUPPLY EXPANSION SYSTEM AND METHOD THEREOF
First Claim
1. A power-supply expansion system comprising:
- a primary power-supply unit providing a main power supply;
a secondary power-supply unit providing an auxiliary power supply;
a power unit comprising a first input terminal, a second input terminal, and an output terminal;
the first input terminal receiving the main power supply or the auxiliary power supply, the second input terminal receiving the auxiliary power supply, the power unit integrating the main power supply and the auxiliary power supply into an output power supply, and the output power supply fed to a load terminal via the output terminal; and
a control unit being connected to the primary power-supply unit and the secondary power-supply unit; and
the control unit, based on a load value of the primary power-supply unit, selectively performing a power-supply expansion process so as to feed the auxiliary power supply to the second input terminal by the secondary power-supply unit.

Abstract
A power-supply expansion system includes a primary power-supply unit for providing a main power supply, a secondary power-supply unit for providing an auxiliary power supply, a power unit having a first and a second input terminal and an output terminal, and a control unit connected to the primary and the secondary power-supply unit. The control unit, based on a load value of the primary power-supply unit, selectively performs a power-supply expansion process for the secondary power-supply unit to feed the auxiliary power supply to the second input terminal. In the power-supply expansion process, the first input terminal receives the main power supply and the second input terminal receives the auxiliary power supply, and the power unit integrates the main and the auxiliary power supply into an output power supply, which is output via the output terminal. A power-supply expansion method applicable to the power-supply expansion system is also disclosed.

7. A power-supply expansion method applicable to a power-supply expansion system, comprising the following steps:
-
monitoring a plurality of feedback messages fed back from a plurality of monitoring points of the power-supply expansion system by a control unit; determining, based on the monitored feedback messages, whether the power-supply expansion system has to simultaneously provide a main power supply to a first input terminal and an auxiliary power supply to a second input terminal by the control unit; performing a power-supply expansion process for feeding the main power supply to the first input terminal and feeding the auxiliary power to the second input terminal, if the power-supply expansion system has to simultaneously provide a main power supply to a first input terminal and an auxiliary power supply to a second input terminal by the control unit; and integrating the main power supply and the auxiliary power supply into an output power supply and outputting the latter to an output terminal. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
