The invention discloses a power supply control circuit, a power supply control method and a power supply control device. The power supply control circuit comprises a first power module, a second power module and a switch module; the first power module is connected with the power utilization module; the second power module is connected with the power utilization module through the switch module; when the voltage of the first power supply module is greater than or equal to the threshold voltage, the switch module is switched off, and the first power supply module is used for supplying power to the power utilization module; and under the condition that the voltage of the first power supply module is smaller than the threshold voltage, the switch module is switched on, and the second power supply module is used for supplying power to the power utilization module. According to the embodiment of the invention, the power supply reliability can be improved.
