Compared with prior art, the beneficial effects of the utility model are: this utility model long-life Portable photovoltaic portable power source simple in construction, components and parts are few, use solar powered, and use the 3V solar panels of small size as photo-electric conversion element, the purpose of high voltage output is reached in conjunction with boost chip, it is greatly reduced the volume of portable power source, under-voltage power supply can also be prevented simultaneously, therefore have that volume is little, diverse in function and an advantage easy to use.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of long-life Portable photovoltaic portable power source.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，A kind of long-life Portable photovoltaic portable power source，Including diode D1、Chip IC 1、Solar panels T and audion V1，The anode of described diode D1 connects solar panels T，The negative electrode of diode D1 connects positive pole and the inductance L1 of accumulator E，The other end of inductance L1 connects anode and the pin 2 of chip IC 1 of diode D2，The negative electrode of diode D2 connects electric capacity C3、Resistance R1、Load A and the pin 3 of chip IC 1，The negative pole of accumulator E connects the other end of electric capacity C3、The anode of diode D4、The fixing end of of potentiometer RP1、The sliding end of potentiometer RP1、The other end of solar panels T and the pin 1 of chip IC 1，The base stage of the other end connecting triode V1 of resistance R1 and the negative electrode of diode D4，The emitter stage of audion V1 connects resistance R2 and resistance R3，The other end of resistance R2 connects the negative electrode of diode D3 and another fixing end of potentiometer RP1，The other end of resistance R3 connects the anode of diode D3，The model of described chip IC 1 is SL8203.
Diode D3 is light emitting diode.Solar panels T is 3V solar panels.
nullOperation principle of the present utility model is: when daytime is bright and clear，Solar panels T is completed in opto-electronic conversion the accumulator that is stored in by non-return diode D1 by electric energy，Owing to the design is Portable power source，In order to reduce volume，Use 3V small size solar panels，Therefore the inductance L1 in circuit、Electric capacity C3、Diode D2 and chip IC 1 constitute DC-DC booster circuit，The low-voltage of the low-voltage output for solar panels or accumulator being exported is increased to the DC voltage that be enough to drive load A work，Output voltage is added in the base stage of audion V1 after resistance R1 and diode D4 dividing potential drop，Audion V1 is turned on，Load A obtains electric，Light emitting diode D3 lights simultaneously，Regulator potentiometer RP1 can change the voltage being added in load A two ends，Carrying out along with charging，The voltage of accumulator E constantly reduces，When being reduced to under-voltage marginal value，Its output voltage turns on insufficient for audion V1 base stage，Now audion V1 cut-off，Load A electric loop disconnects，Prevent under-voltage power supply，Light emitting diode D3 extinguishes simultaneously.
