ABSTRACT:
A power control system for use in an electronic device provided with a transforming module becoming self-contained upon connection with a power supply includes a switch module, a delay module, and a control module. The switch module turns on or off a power input route whereby the transforming module can supply power to the electronic device, and keeps the power input route at an off state while the transforming module remains unconnected to the power supply. The delay module performs a delay process and generates delay signals. The control module receives the delay signals generated and enables the switch module to turn on the power input route. The present invention prevents the stability of the electronic device from being deteriorated as a result of electric sparks induced by metallic friction and excessive instantaneous current while the electronic device is being connected to the power supply.
