Embodiment Construction

[0037] figure 1 It is a block diagram of a power circuit according to a preferred embodiment of the present invention. Please refer to figure 1 The power supply circuit 100 provided in this embodiment includes a power detection unit 102, a control unit 104, and a switching unit 106. In this embodiment, the power detection unit 102 is electrically coupled to the control unit 104 and the switching unit 106, and the control unit 104 and the switching unit 106 are further electrically coupled to the load 116.

[0038] Please continue to refer figure 1 The power detection unit 102 is used to detect whether multiple power sources including the green power source 112 (for example, the additional power source 114) are provided to the power circuit 100. When the green power supply 112 is provided to the power supply circuit 100, the green power supply 112 can generate the output voltage V1 to the power detection unit 102. In some alternative embodiments, the power detection unit 102 may ...

Abstract

The invention discloses a power circuit which comprises a power detection unit, a control unit and a switching unit, wherein the power detection unit is used for detecting whether a plurality of power supplies, including a green power supply, are provided to the power circuit or not and also detecting a power value provided by the green power supply; in addition, the control unit is electrically coupled to the power detection unit and a load so as to detect the electricity consumption power of the load and output a switching signal to the switching unit according to the electricity consumption power of the load and the detection result of the power detection unit. Therefore, the switching unit can select the green power supply and at least one other power supply to supply the electricity to the load if necessary according to the switching signal.

Description

Technical field [0001] The present invention relates to a power management technology, and particularly relates to a power management technology including green power and commercial power. Background technique [0002] For various current portable electronic products, such as Personal Digital Assistant (PDA), Notebook Computer (Notebook Computer), electronic dictionary, digital camera, etc., a battery is a necessary equipment. Since rechargeable secondary batteries (or rechargeable batteries) have an economical and environmentally friendly power supply method, they are becoming increasingly popular in the use of portable electronic products. Among them, rechargeable batteries are the most widely used lithium batteries. [0003] Generally, a battery charger must be used to charge the secondary battery, and the battery charger converts the indoor commercial power into a charging power source with a certain voltage level through a transformer, and uses the charging power source to ch...
