Abstract
A power supply includes a first and second power conversion modules, changeover switch and control module. The first power conversion module provides at least one working power and generate a power good signal. The power conversion efficiency of the second power conversion module is lower than that of the first power conversion module. The second power conversion module provides a backup power permanently. The control module includes a switch control unit connected to the changeover switch, and a voltage drop adjustment unit connected to the second power conversion module. The control module is provided with a first state, in which the power good signal is not received such that the backup power is outputted continuously, and a second state, in which the changeover switch is turned on while the backup power is dropped to be replaced by the working power from the changeover switch on receiving the power good signal.
