| Zusammenfassung: | The invention provides a power supply control system which is used for supplying power to a load and comprises a first power supply device, a second power supply device and a step-down converter. The first power supply device has a first output voltage and is used for outputting a first output current to a load. The second power supply device has a second output voltage and is used for outputting a second output current to the load. The buck converter is selectively connected with the first power supply device or the second power supply device, and then is connected in parallel with the unconnected power supply device and the load. The buck converter is selectively connected to a power supply device with a high output voltage according to the first output voltage and the second output voltage, and controls the output voltage of the converter to accord with the voltage of the other power supply device, so that the two power supply devices are connected in parallel, and current is output to a load.
