Description
Technical field
The utility model relates to a kind of portable power source, specifically a kind of solar energy movable power supply.
Background technology
Solar energy is as a kind of regenerative resource of energy-conserving and environment-protective, be applied to various energy field gradually, especially generating aspect, little of solar street light, large to circumlunar satellite, all make use of solar energy as the energy, especially in remote mountain areas, power circuit often damages, inconvenient maintenance causes the area of frequent power-off, utilize solar energy stand-by power supply effectively can alleviate the problem of electricity consumption difficulty, but at present because the voltage of solar power generation affects seriously by ambient lighting, larger fluctuation is had with output voltage during sunlight deficiency sunny, therefore its power supply quality is lower, long-time use can reduce the life-span of power consumption equipment, therefore popularity rate is not high.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the solar energy movable power supply of stable output, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of solar energy movable power supply, comprise solar panels T, storage battery E, triode V1 and chip IC 1, one end of described solar panels T connects the anode of diode D1, the negative electrode of diode D1 connects electric capacity C1, resistance R1, the collector electrode of triode V1, the collector electrode of triode V2, the positive pole of storage battery E and the pin 7 of chip IC 1, the other end of electric capacity C1 connects electric capacity C2, electric capacity C3, the anode of diode D2, the negative pole of storage battery E, the other end of solar panels T, the pin 4 of chip IC 1 and the negative pole of output voltage U1, the base stage of triode V1 connects the pin 6 of chip IC 1, the base stage of the emitter connecting triode V2 of triode V1, the emitter of triode V2 connects the other end of electric capacity C2, the other end of electric capacity C3, the pin 2 of chip IC 1 and the positive pole of output voltage U1, the other end of resistance R1 connects the negative electrode of diode D2 and the pin 3 of chip IC 1, the model of chip IC 1 is UA741.
As preferred version of the present utility model: described solar panels T is mono-crystalline silicon solar plate.
Compared with prior art, the beneficial effects of the utility model are: the utility model solar energy movable power supply structure is simple, components and parts are few, adopt operational amplifier μ A741 as comparing control element, realize controlling the stability of output voltage by triode and electric capacity, reduce Intensity of the sunlight to the impact of output voltage, therefore have that cost of manufacture is low, the advantage of stable performance.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of solar energy movable power supply.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of solar energy movable power supply, comprise solar panels T, storage battery E, triode V1 and chip IC 1, one end of described solar panels T connects the anode of diode D1, the negative electrode of diode D1 connects electric capacity C1, resistance R1, the collector electrode of triode V1, the collector electrode of triode V2, the positive pole of storage battery E and the pin 7 of chip IC 1, the other end of electric capacity C1 connects electric capacity C2, electric capacity C3, the anode of diode D2, the negative pole of storage battery E, the other end of solar panels T, the pin 4 of chip IC 1 and the negative pole of output voltage U1, the base stage of triode V1 connects the pin 6 of chip IC 1, the base stage of the emitter connecting triode V2 of triode V1, the emitter of triode V2 connects the other end of electric capacity C2, the other end of electric capacity C3, the pin 2 of chip IC 1 and the positive pole of output voltage U1, the other end of resistance R1 connects the negative electrode of diode D2 and the pin 3 of chip IC 1, the model of chip IC 1 is UA741.
Solar panels T is mono-crystalline silicon solar plate.
Operation principle of the present utility model is: mono-crystalline silicon solar plate has the advantage that volume is little, the life-span is long and photoelectric conversion efficiency is high, therefore very the design is suitable for, solar panels T completes opto-electronic conversion and is charged by electric energy part accumulators E, another part powers to the control circuit be made up of elements such as triode V1, triode V2 and chip IC 1, circuit adopts operational amplifier μ A741 as comparing control element, triode V1 and V2 is as adjustment element, and circuit working is on off state.As output voltage U1 2mV lower than reference voltage, namely 2 pin of chip IC 1 are than the low 2mV of 3 pin (because the reaction sensitivity of μ A741 is 2mV), 6 pin of chip IC 1 export high level, control V1 and V2 conducting, take big current as the electric energy supplement such as load and relevant filter capacitor C2, C3, make output voltage be raised to 12V very soon, namely 2,3 pin current potentials of chip IC 1 are equal.Its 6 pin output LOW voltage (2V), V1, V2 close, and suspend power supply.Along with the growth of time, output voltage declines gradually, repeats said process again, goes round and begins again, and power supply continues to be on off state, and makes output voltage U1 all-the-time stable.
