Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Refer to Fig. 1, a kind of intelligence communication booster power, including resistance R1, switch S1, triode V1 and power supply E, it is described The positive pole connecting valve S1 of power supply E, switch the other end connection electric capacity C1 of S1, the anode of diode D1, one of potentiometer RP1 Fixing end, the sliding end of potentiometer RP1, the winding N2 of the winding N1 of transformer W and transformer W, the winding N1's of transformer W is another One end connects electric capacity C2, the base stage and another fixing end of potentiometer RP1 of the other end connecting triode V1 of electric capacity C2, three poles The other end and the negative pole of battery E of the emitter stage connection electric capacity C1 of pipe V1, the colelctor electrode connection transformer W of triode V1 around The other end, the negative electrode of diode D1 and the ground of N2 are organized, one end of the winding N3 of transformer W connects the anode of diode D2, two poles The anode of the other end connection diode D3 of the negative electrode connection electric capacity C3, the negative electrode of diode D3 and load A, electric capacity C3 of pipe D2, Load the other end of the winding N3 of the other end and transformer W of A.

Diode D3 is voltage-regulator diode.

Operation principle of the present utility model is：When using, closure switch S1, due to being just switched on power supply, can be produced small Voltage pulsation, triode V1 can amplify this small electro-mechanical wave, the first winding N1 of transformer obtain one it is larger Fluctuation signal, necessarily has certain frequency to transformer first winding N1 resonance in this signal.Because circuit is connected into positive feedback, Electric capacity C2 feeds back to the sub-fraction in resonance signal the base stage of V1, and V1 amplifies this signal repeatedly, for supplementary loop The energy of loss, as a result sets up constant vibration in Transformer Winding, after the secondary end winding N3 of transformer W produces boosting Voltage, this voltage by diode D2 rectifications, electric capacity C3 filter and diode D3 voltage stabilizings after to communication equipment A provide it is higher Driving DC voltage.

It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation Involved claim.

Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined May be appreciated other embodiment.
