Description

A kind of dual power supply direct current stabilizer
Technical field
This utility model is related to a kind of manostat, specifically a kind of dual power supply direct current stabilizer.
Background technology
Since lead-acid accumulator is invented 150 years, it occupies absolute advantage in chemical energy battery always.This is because It is cheap, using reliability, be suitable for heavy-current discharge, adapt to ambient temperature range width the advantages of.Lead-acid accumulator is being handed over The fields such as logical, communication, military affairs, navigation, aviation, photovoltaic generation suffer from important function.Particularly in dual power supply field, often It is ready for use on and other power supply combines, effectively guarantee the uninterrupted power supply of electrical equipment, existing double power supply circuit is most Single function, easily causes the overcharge of accumulator, thus affecting its service life.
Utility model content
The purpose of this utility model is to provide a kind of dual power supply direct current stabilizer, to solve to propose in above-mentioned background technology Problem.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of dual power supply direct current stabilizer, including audion v1, diode d3, chip ic1 and accumulator e, described electric power storage The positive pole of pond e connects resistance r1, the pin 3 of the negative electrode of diode d3, power supply vcc and chip ic1, and the other end of resistance r1 connects The negative electrode of diode d1 and the emitter stage of audion v1, the anode of diode d1 connects the anode of diode d2, diode d2's The base stage of negative electrode connecting triode v1, the colelctor electrode of audion v1 connects negative pole, electric capacity c1, resistance r3 and the load of accumulator e The anode of a, diode d3 connects resistance r2, the other end of the negative electrode of diode d4, the pin 2 of chip ic1 and load a, resistance The other end of r2 connects the anode of diode d4, the pin 1 of the other end of electric capacity c1, the other end of resistance r3 and chip ic1, institute State model lm317 of chip ic1.
As preferred version of the present utility model: described diode d1 is Zener diode.
Compared with prior art, the beneficial effects of the utility model are: this utility model dual power supply direct current stabilizer structure Simply, components and parts are few, increased accumulator in circuit as stand-by power supply, and are provided with the module preventing overcharge, effectively Protect accumulator from overcharge, circuit has the function of voltage stabilizing output simultaneously, therefore have long service life, stable performance and Advantage vdiverse in function.
Brief description
Fig. 1 is the circuit diagram of dual power supply direct current stabilizer.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of dual power supply direct current stabilizer, including audion v1, diode d3, chip ic1 and accumulator E, the positive pole of described accumulator e connects resistance r1, the pin 3 of the negative electrode of diode d3, power supply vcc and chip ic1, resistance r1's The other end connects the negative electrode of diode d1 and the emitter stage of audion v1, and the anode of diode d1 connects the anode of diode d2, The base stage of the negative electrode connecting triode v1 of diode d2, the colelctor electrode of audion v1 connects the negative pole of accumulator e, electric capacity c1, electricity The anode of resistance r3 and load a, diode d3 connects the another of resistance r2, the negative electrode of diode d4, the pin 2 of chip ic1 and load a One end, the other end of resistance r2 connects anode, the other end of electric capacity c1, the other end of resistance r3 and the chip ic1 of diode d4 Pin 1, model lm317 of described chip ic1.
Diode d1 is Zener diode.
Operation principle of the present utility model is: when civil power is normal, power supply vcc is that line voltage obtains after rectifier bridge blood pressure lowering The Rectified alternating current arriving, one part is charged to accumulator e, and another part is through by chip ic1, resistance r2, diode The Voltage stabilizing module of the original papers such as d4 composition, the voltage exporting from chip ic1 is powered to load a, the audion v1 in circuit, diode D1 and diode d2 composition prevents overcharge module, and when the voltage of accumulator e is relatively low, Zener diode d1 is in cut-off shape State, audion v1 is not turned on, and constantly raises with the cell voltage that carries out charging, when cell voltage reaches puncturing of stabilivolt d1 When more than voltage, d1 begins to turn on, and now v1 is also switched on, and promotes accumulator e both end voltage to decline, reaches the mesh preventing overcharge , after vcc dead electricity, being powered to circuit it is ensured that loading by accumulator e is not affected by power-off.
It is obvious to a person skilled in the art that this 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, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting Involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment only wraps Containing an independent technical scheme, only for clarity, those skilled in the art should for this narrating mode of description Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined Understandable other embodiment.
