Accompanying drawing explanation
Fig. 1 is the circuit diagram of photovoltaic voltage stabilizing charging circuit.
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 carried out Clearly and completely describe, 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 making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of photovoltaic voltage stabilizing charging circuit, including audion V1, diode D1, unidirectional thyristor Q2 and electricity The anode of resistance R5, described diode D1 connects the negative electrode of solar panels T, diode D1 and connects resistance R1, the current collection of audion V1 Pole and the positive pole of accumulator E, the base stage of audion V1 connects the sliding end of potentiometer RP1, and the other end of resistance R1 connects current potential The fixing end of of device RP1, another fixing end of potentiometer RP1 connect electric capacity C1, resistance R4, one of potentiometer RP2 solid Fixed end, the negative electrode of unidirectional thyristor Q2, accumulator E1, the negative pole of accumulator E2 and the other end of solar panels T, audion V1's Emitter stage connects the anode of diode D2, resistance R5 and the anode of unidirectional thyristor Q1, and the negative electrode of diode D2 connects resistance R2, The other end of resistance R2 connects resistance R3, the anode of accumulator E2 and the negative electrode of unidirectional thyristor Q1, the control of unidirectional thyristor Q1 Pole processed connects the negative electrode of diode D3, and the anode of diode D3 connects the other end and the anode of unidirectional thyristor Q2 of resistance R5, The other end of resistance R3 connects another fixing end of potentiometer RP2, and the sliding end of potentiometer RP2 connects the negative electrode of diode D4 With the other end and the control pole of unidirectional thyristor Q2 that the anode of electric capacity C1, diode D4 connects resistance R4.
Diode D4 is Zener diode.
Operation principle of the present utility model is: during daylight abundance, and solar panels T completes opto-electronic conversion and by two poles An electric energy part is stored in accumulator E1 by pipe D1, and another part is powered to circuit, resistance R1, potentiometer RP1 and audion V1 forms under-voltage protective module, and when voltage is normal, the voltage after resistance R1 and potentiometer RP1 dividing potential drop makes audion V1 lead Logical, circuit below obtains electric, the electricity when voltage of accumulator E2 to be charged is relatively low, after resistance R3 and potentiometer RP2 dividing potential drop Pressure is insufficient for the conducting of diode D3, therefore unidirectional thyristor Q2 cut-off, the voltage exported from the emitter stage of audion V1 The control pole of unidirectional thyristor Q1 it is added in so that it is conducting through resistance R5 and diode D3, the high-power charging of accumulator E2, along with The carrying out of charging, the voltage of E2 constantly raises, and after E2 is full of, the voltage after resistance R3 and potentiometer RP2 dividing potential drop makes The conducting of diode D4, unidirectional thyristor Q2 turns on, so that Q1 cut-off, accumulator E2 now can only be by D2 after diode Carry out trickle charge with resistance R2, thus prevent overcharge, when running into the output voltage deficiency of solar energy T and E1, audion V1 Cut-off, disconnects charge circuit, reaches the purpose of under-voltage protection.
