Accompanying drawing explanation
Fig. 1 is the circuit diagram of solar telephone charging circuit.
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 telephone charging circuit, comprise solar panels T, diode D3, triode V1 and Schmidt trigger U1, one end of described solar panels T connects the negative electrode of diode D3, electric capacity C1, the collector electrode of triode V1 and inductance L 1, the anode of diode D3 connects the other end of electric capacity C1, electric capacity C2, electric capacity C3, resistance R3, storage battery E, the emitter of triode V2 and the other end of solar panels T, the other end of the emitter contact resistance R3 of triode V1, the base stage of triode V1 connects the anode of diode D1, the negative electrode of diode D1 connects the negative electrode of diode D2, the other end of electric capacity C2 and the positive pole of storage battery E, the anode of diode D2 connects the other end of inductance L 1 and the collector electrode of triode V2, the base stage contact resistance R2 of triode V2, the other end of resistance R2 connects Schmidt trigger U2, the other end contact resistance R1 of Schmidt trigger U2 and Schmidt trigger U1, the other end of other end contact resistance R1 of Schmidt trigger U1 and the other end of electric capacity C3.
Solar panels T is mono-crystalline silicon solar plate.
Operation principle of the present utility model is: the Schmidt trigger U1 in circuit makes oscillator, frequency of oscillation is determined by the value of R1 and C3, because frequency of oscillation can not exceed the maximum of the ripple frequency on output capacitor C2, thus require that frequency of oscillation should lower than 100kHz.U2 makes buffer, makes oscillator output end obtain a lighter constant load.Play buffer action, ensure that frequency stabilization.The power supply of IC1 directly can be linked on output rechargeable battery and obtain.V2 plays on-off action, controls solar cell to the charging of storage battery.When buffer U2 exports high level. transistor V2 conducting, collector current stores magnetic field energy through inductance L 1.And set up reverse voltage VL1, when buffer U2 output low level, transistor V2 ends, the polarity of VL1 becomes anti-, and superpose with solar array voltage, electric current flows into load through inductance L 1, diode D1, electric capacity C2 and battery E is charged, output voltage will higher than input voltage at steady state, and when after transistor V2 again conducting, process repeats.Centered by transistor V1, form shunt regulator, cause battery damage to prevent overcharge.And ensure output voltage stabilization, once overcharge, output voltage is raised, during overrate, voltage-stabiliser tube D1 punctures and makes transistor V1 conducting, and the electric current of solar cell enters ground through the R3 of V1 and low resistance, and storage battery can not overcharge.When battery tension is lower than voltage stabilizing value, voltage-stabiliser tube D1 is obstructed, and V1 ends, and charging process recovers again normal.
