Power switching system, computer system, and reboot controlling method thereof

摘要

A power switching system, a computer system, and a reboot controlling method thereof are disclosed. The power switching system is used to the computer system and includes a first power input port, a first power output port, a first linear regulator module, and a first switch module. The first power input port is used for inputting a first power signal. The first power output port is used for outputting a second power signal. The first linear regulator module includes a first transformer unit used for transforming the first power signal into the second power signal, and a first switch control unit used for controlling the first transformer unit. When the first switch module is activated, the first switch control unit is connected to a ground and controls the first transformer unit to stop outputting the second power signal.
