Embodiment 1

[0074] Since different electronic devices have different rated input voltages, in order to realize the adaptive change of the output voltage of the power system, it is necessary to provide identification information from the device side to the power side to indicate the required voltage signal level.

[0075] Fig. 1 shows an adaptive power supply system according to a first embodiment of the present invention. The adaptive power supply system 100 includes a power supply unit 101 , a device power interface 120 and a device 130 .

[0076] The device power interface 120 includes a power supply terminal VCC121 , a ground voltage terminal GND122 , data terminals D+ and D−, a voltage stabilizing module 123 and a control unit 124 . The power terminal VCC121 and the ground voltage terminal GND122 are connected to the power input terminal of the device 130 .

[0077] The input of the voltage stabilizing module 123 is connected to the power supply terminal VCC121 and the ground voltage...

Embodiment 2

[0090] Although the device power interface device of the connected device can provide the power supply unit with indication information, because the control unit in the device power interface only stores one ID information, it can only be used for a class of electronic devices that require the same input power. In order to be suitable for electronic equipment with different voltage requirements, in one case, it is necessary to change the ID information stored in the control unit in the equipment power interface to correspond to different voltage signals, so that the equipment power interface device can be commonly used for power supply of different electronic equipment, However, this requires additional modifying means to modify the ID information.

[0091] figure 2 An adaptive power supply system according to a second embodiment of the present invention is shown. The adaptive power system 200 includes a power supply unit 201 , a device power interface 220 and a device 230 ....

Embodiment 3

[0100] In the second embodiment, although the card-type device power interface can be used to supply power to different electronic devices by replacing circuit boards with different ID information, but due to the wide variety of electronic devices, at the same time It is not easy to know the power requirements of all known or unknown electronic devices. This may cause the user to carry a large number of circuit boards, or the power supply system cannot be used because there is no corresponding circuit board.

[0101] Figure 3A An adaptive power supply system according to a third embodiment of the present invention is shown. The adaptive power system 300 includes a power supply unit 301 , a device power interface 320 and a device 330 .

[0102] The connection relationship between the power supply unit 301, the device power interface 220 and the device 230 is the same as that of the first and second embodiments, and the internal structure of the device power interface 220 is ...

Abstract

The invention relates to a self-adaptive power system and a power supply method of the self-adaptive power system. According to the self-adaptive power system and the power supply method, a power interface of a device is adopted to send identification information corresponding to device power requirements to a power supply unit, the power supply unit changes the voltage level of output power according to the identification information, and therefore self-adaptive power supply is achieved. By means of the system and method, a power supply can be accurately matched with the device, power system output can be changed in a self-adaptive mode according to the input power requirement of the known device, and the power system output also can be changed through external control. Portability, universality and flexibility of the power system are improved.

Description

technical field [0001] The invention relates to a power supply system and a power supply method, in particular to a power supply system and a power supply method that can adaptively change the output according to the needs of electric equipment. [0002] Background technique [0003] With the rapid development of the global economy and the continuous improvement of people's living standards, more and more digital products have entered life in the form of different function providers, such as notebook computers, tablet computers, mobile phones, digital cameras, video cameras, portable DVD , PDA, MP3, MP4, GPS, thermal equipment, health care equipment, etc. [0004] Usually in an indoor environment, these devices can use a power adapter (Power adapter) to directly connect to a mains power outlet to obtain power. The power adapter is a small portable electronic device and a power supply conversion device for electronic appliances. It is generally composed of a casing, a power...
