Abstract:
A power-saving control apparatus for reducing power consumption of a power supply is provided. The present invention includes a switching circuit and a rectifier circuit. The rectifier circuit rectifies an AC signal to a DC signal. The switching circuit controls either the AC signal or the DC signal as an input signal to an EMI filter of the power supply. Therefore, when the EMI filter receives the DC signal, the present invention achieves the effect of power-saving of the power supply.
