Embodiment Construction

[0012] Such as figure 1 As shown in , the triangle in the figure represents the input / output interface (the two triangles backed by a rhombus represent an interface that has both input and output functions and can be connected to the battery compartment). Solid line boxes 1-8 represent functional circuit modules. A dotted box 9 represents an interface converter (extender). Solid lines and arrows indicate the direction of power transmission. Dashed lines and arrows indicate the direction of information transmission.

[0013] The feasible ways of implementing each function of the present invention are respectively described through specific situations.

[0014] When you need to use 220V AC power supply to power MP3, first find out the voltage (current) in the MP3 user manual (or the original attached adapter), such as 5.0V (200mA). Connect the 220V AC power input interface of the present invention to the AC power supply, and the AC / DC conversion circuit module 1 converts the...

Abstract

A multifunctional power adapter comprises a plurality of input / output interfaces, an interface converter, an external battery box and a circuit capable of achieving input protection, overload protection, undervoltage protection, transformation control, AC-DC conversion, voltage (current) indication, alarming and state detection function, wherein each interface can achieve connection between different power supplies and power consuming equipment. Under the indication of a digital voltage meter (current meter), desired voltage (current) can be output by adjusting the transformation ratio of a transformer circuit. When an accident occurs, the input protection, the overload protection and the undervoltage protection function can protect the safety of the internal circuit, the power consuming equipment and the power supply. An alarm / state detection circuit sends an alarm or indicates the work state when detecting an alarm or state information.

Description

technical field [0001] The present invention relates to the adaptation between various power sources and various electric equipments, such as the adaptation between 220V AC power supply and mobile phone, the adaptation between No. 5 dry battery and MP3, the adaptation between automobile DC power supply and notebook computer adaptation. Background technique [0002] With the advancement of science and technology, people's living standards continue to improve, and more and more people have a variety of electronic products, such as: radios, MP3, mobile phones, CD players, digital cameras, notebook computers, etc. When users purchase these electronic products, they are basically equipped with specific power adapters. However, the input and output voltage, current, power, and interface of these adapters are fixed, and can only be applied to specific power sources and electronic devices. When a power failure occurs, even if there are other power sources (such as storage batterie...
