Abstract
A power supply and a power saving method thereof are provided. The power saving method includes: utilizing a monitoring circuit within the power supply to generate a monitoring signal according to operating loading of the power supply; and utilizing a control signal generating circuit within the power supply to generate a control signal according to the monitoring signal, to drive at least two switch transistors within a circuitry within the power supply, wherein the switch transistors are connected in parallel.
Claims10
A power saving method of a power supply, comprising:
- utilizing a monitoring circuit within the power supply to generate a monitoring signal according to operating loading of the power supply;
- and
- utilizing a control signal generating circuit within the power supply to generate a control signal according to the monitoring signal, to drive at least two switch transistors within a circuitry within the power supply, wherein the switch transistors are connected in parallel;
- wherein the step of generating the control signal according to the monitoring signal to drive the switch transistors within the circuitry within the power supply comprises controlling a voltage level of the control signal according to the monitoring signal;
- wherein the step of controlling the voltage level of the control signal according to the monitoring signal comprises when the monitoring signal indicates that the power supply enters a light loading status, lowering the voltage level of the control signal which is configured to conduct the switch transistors by at least one-third.
