Power supply control circuit, power supply control method, and apparatus

Abstract

A power supply control circuit, a power supply control method, and an apparatus are disclosed. The power supply control circuit includes a first power module, a second power module, and a switch module; where the first power module is connected to an electric module; the second power module is connected to the electric module through the switch module; in a case that a voltage of the first power module is greater than or equal to a threshold voltage, the switch module is turned off, and the first power module is configured to supply power to the electric module; and in a case that the voltage of the first power module is less than the threshold voltage, the switch module is turned on, and the second power module is configured to supply power to the electric module. According to embodiments of this application, power supply reliability can be improved.
