POWER SOURCE CIRCUIT AND POWER SOURCE MANAGEMENT METHOD THEREOF
First Claim
1. A power source circuit, comprising:
- a power source detection unit, detecting whether a plurality of power sources including a green power source is supplied to the power source circuit, and detecting a power value supplied by the green power source;
a control unit, electrically coupled to the power source detection unit and a load, the control unit further detecting a power consumption value of the load, and generating a switch signal according to the power consumption value of the load and a result detected by the power source detection unit; and
a switch unit, electrically coupled to the control unit and the power source detection unit, and configured for selecting the green power source and at least one of other power sources of the plurality of power sources to supply electric power to the load when the power value of the green power source is less than the power consumption value of the load.

Abstract
A power source circuit includes a power source detection unit, a control unit and a switch unit. The power source detection unit detects whether a plurality of power sources including a green power source is supplied to the power source circuit, and detects and outputting a power value of the green power source. In addition, the control unit is electrically coupled to the power source detection unit and a load, and the control unit further detects a power consumption value of the load, to generate a switch signal to the switch unit according to the power consumption value of the load and a result detected by the power source detection unit. Therefore, the switch unit selects the green power source and at least one of other power sources thereof to supply electric power to the load when necessary.
