Abstract:
A system for power management electrically connected to a solar cell is provided. The system for power management includes a photo-sensor, a controller electrically connected to the photo-sensor, and a power manager. The photo-sensor detects an illumination (illuminance or irradiance) of an environment where the solar cell is located. A look-up table of illumination vs. maximum output power is built in the controller, wherein a corresponding maximum output power is determined by the controller according to the illumination detected by the photo-sensor. The power manager is electrically connected to the controller and the solar cell. The power manager controls the output current of the solar cell so as to equalize an output power of solar cell and the corresponding maximum output power. A method for power management is also provided.

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.
