Abstract
A power system having a power saving mechanism includes a voltage regulator, a power input module, and a switching signal generation unit. The voltage regulator performs a regulation operation on a first voltage for generating a second voltage. The power input module includes a transformer, a rectifying unit, a switch, and a switch control unit. The rectifying unit together with the transformer is put in use for converting an input voltage into the first voltage. The switch is employed to control a current flowing through the primary winding of the transformer. The switch control unit generates a control signal for controlling the switch according to a switching signal. The switching signal generation unit is utilized for generating the switching signal to disable the switch control unit during an energy transfer disable interval so as to decrease the first voltage from a first predetermined voltage to a second predetermined voltage.
