Embodiment Construction

[0029] Next, the embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 It is a circuit block diagram of a system device with an identifiable power adapter according to an embodiment of the present invention. figure 2 and image 3 Respectively represent the schematic diagram of the DC output potential of the power adapter and the waveform diagram of the carrier DC signal after the carrier is added to the DC output potential. In this embodiment, the biggest technical feature is that all power adapters can use the same connector, and then use the system device to determine whether the type (power) of the power adapter is compatible with the system device.

[0030] exist figure 1 Among them, a system device with an identifiable power adapter includes a system end 100 and an adapter end 150 . Wherein, the system terminal 100 includes a power adapter identification device 110 and a system device 130 . The adapter end 150 in...

Abstract

The invention relates to a system device capable of identifying power supply adapter and its identification method. Said system device includes power supply adapter end and system end. Said power supply adapter end utilizes the frequency generator to add the carrier correspondent to it on the DC output potential of said adapter, then output the carrier DC signal. The power suppply adapter identification device being in said system end can eliminate the DC output potential from carrier DC signal, then converts the carrier into the DC level correspondent to it, and utilizes its judgement circuit to judg the type of the adapter.

Description

technical field [0001] The present invention relates to a system device and method capable of automatically identifying a power adapter, and in particular to a system device and method capable of judging whether a power adapter plugged into the system device is compatible with the system device. Background technique [0002] Portable electronic devices, such as notebook computers (Notebook), personal digital assistants (personal digital assistant, PDA), digital still / dynamic cameras (digital still / dynamic camera), etc., all need to use DC power as electronic devices when in use source of power. A commonly used one is a so-called AC adapter. This power adapter can convert general AC power into DC power required by electronic devices. In addition, in order to allow the electronic device to operate smoothly, the power adapter can provide a certain amount of power for the operation of various components in the electronic device. [0003] In recent years, taking notebook compu...
