Abstract

A dual power supply system includes a main power supply module, a standby power supply module, a first transistor switch, a second transistor switch and a dual power controller. The first transistor switch is coupled to the main power supply module and an output terminal to control the main power supply module supplying electric power to the output terminal. The second transistor switch is coupled to the standby power supply module and the output terminal to control the standby power supply module supplying electric power to the output terminal. The dual power controller detects a main power voltage generated by the main power supply module. When the main power voltage reaches a preset voltage value, the first transistor switch is tumed on by the dual power controller for supplying the electric power of the main power supply module to the output terminal and the second transistor switch is turned off for a preset delay time to stop supplying the electric power of the standby power supply module to the output terminal. After that, the dual power controller performs a protect process when detecting the main power voltage lowers to a preset protect voltage value.
