Embodiment Construction

[0015] See figure 1 , Is an external perspective view of the power supply 10 capable of detecting and adjusting the voltage and current required by electronic products of the present invention. The power supply 10 includes a display device 18. The power supply 10 is provided with an AC power input port 14 and a DC power input port 16. The AC power input port 14 is an adapter for plugging in AC power (not shown) To input AC power, the DC power input port 16 is an adapter (not shown) for plugging in DC power to input DC power. The display device 18 is arranged on the surface of the power supply 10 to indicate the power parameters currently output by the power supply, such as DC voltage or current value. The display device 18 may be a liquid crystal display or other display devices.

[0016] See figure 2 , Is a schematic diagram of another embodiment of the display device of the power supply. The display device 19 is arranged on the surface of the power supply 10 and is composed of...

Abstract

The electrical source provider includes AC power input port, a DC power input port, and a display device. The electrical source provider also includes an electrical source adjustment circuit. The electrical source adjustment circuit includes a unit for selecting input of electrical source, an AC-DC converter, a voltage control unit, a current stabilizer, a pulse wave detector, a microprocessor, and display for output voltage and current. Being capable of detecting and adjusting voltage and current needed by electronic product, the method can detect DC voltage and current needed by electronic product step by step and adjust DC power supply outputted from the electrical source provider in order to supply DC voltage and current of electrical source needed by electronic product.

Description

【Technical Field】 [0001] The invention relates to a power supply capable of detecting and adjusting the voltage and current required by an electronic product and a method thereof, in particular to a power supply having an output power detection and adjustment device for detecting and outputting electronic products The power required. 【Background technique】 [0002] With the popularization of mobile electronic products, mobile phones, personal digital assistants (PDAs) and digital music players (such as Apple iPod, MP3 Player, etc.) have become electronic devices carried by modern people. These mobile electronic products not only fulfill the purpose of mobile communication and data storage, but also further satisfy consumers' demand for entertainment. Most of these mobile electronic products have built-in rechargeable batteries. When the rechargeable battery is exhausted, you can use the power supply of the mobile electronic product to connect to an AC outlet (such as an indoor 11...
