Embodiment

With reference to embodiment and compare accompanying drawing the utility model is described in further detail.It should be emphasized that It is, what the description below was merely exemplary, rather than in order to limit the scope of the utility model and its application.

With reference to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical reference represents Identical part, unless stated otherwise.

In the present embodiment, a kind of notebook adapter, including the input 1 for control source, in the present embodiment, Input inputs 220V~50HZ alternating current, and the input 1 is connected with current rectifying and wave filtering circuit 2, the current rectifying and wave filtering circuit 2 Output end be connected with transformer 4, the output end of the transformer 4 is connected with filter circuit of pressure-stabilizing 5, the rectifying and wave-filtering electricity Switch 3 is provided between road 2 and the transformer 4, the switch 3 is connected with control circuit 9, the control terminal and light of control circuit 9 Coupling 8 is connected, and the optocoupler 8 is connected with reference feedback 6, the output end phase of the reference feedback 6 and the filter circuit of pressure-stabilizing 5 Even；The filter circuit of pressure-stabilizing 5 exports first voltage, and the output end of filter circuit of pressure-stabilizing 5 is connected with multiple voltage conversion moulds Block 7, the first voltage is converted into by multiple second voltages by the voltage transformation module 7.

In 220v alternating current input adapter, turn after current rectifying and wave filtering circuit 2, transformer 4, filter circuit of pressure-stabilizing 5 The direct current of 19V (first voltage) is changed into, in order to meet the output of the multivoltage of adapter, to adapt to more money electronic equipments Adaptation, meets portable function, second voltage can be 5V, can be 12V available for the charging of smart mobile phone, can be to electric power storage Charge in pond.

Voltage transformation module is DC-DC module, and the present embodiment illustrates two DC-DC modules, can root in the present embodiment According to actual conditions, N number of DC-DC Module are set.

As shown in Fig. 2 the output end of the filter circuit of pressure-stabilizing 5 is also associated with the He of radiating circuit 10 for wireless charging Transmitter 11, the output end of the radiating circuit 10 are connected with the transmitter 11.
