Description
Technical field
The utility model relates to a kind of solar battery charger, belongs to technical field of new energies.
Background technology
At present, the globalization raw material reduce day by day, climate warming, and environmental disruption is more and more serious.Because the in short supply and pollution problem of resource, the new forms of energy of development environmental protection have become the key project of various countries' exploitation, and solar energy has solved this difficult problem well as a kind of cleaning, safety, reproducible green energy resource.Sunlight has reserves " unlimitedness " because the generality that sunlight exists, so solar charger can adapt to can not area, region and weather, can take can be extensively general use on the spot.Application percentage is the highest in Future New Energy Source is utilized, resource potential is maximum, development prospect is the most wide for solar energy, and solar battery charger has utilized the advantage of solar energy just.Solar cell is to utilize sunlight to produce electric energy, does not need materials such as consume fuel and water, does not discharge any gas that comprises carbon dioxide in the use, is the regenerative resource of environmentally safe, and this is significant to improving the ecological environment.
Summary of the invention
The technical problems to be solved in the utility model is to develop a kind of solar battery charger, and this charger is the charging device of a kind of low output, high repayment, has to use flexibly, is convenient for carrying advantage simple to operate.
The technical solution of the utility model is: a kind of solar battery charger, formed by solar panel, monolithic processor control device and USB charging inlet; Solar panel links to each other with monolithic processor control device by lead, comprises pressurizer system, integrated manipulator, dual operational amplifier system, button, digital display circuit, chopper circuit and single-chip computer control system in the monolithic processor control device; The USB charging inlet links to each other with monolithic processor control device by lead.
It is electric energy with transform light energy that solar panel absorbs sunlight, power to monolithic processor control device by pressurizer system, pressurizer system is that core and other external circuits are formed with three circle pressurizer LM2940, it makes unsettled voltage enter through being used by Vout output after the voltage stabilizing from Vin, and three circle pressurizer LM2940 are the fixing low pressure reduction three terminal regulators of output voltage; Treating charging device by single-chip computer control system programming realization PWM ripple control chopper circuit and integrated manipulator charges, and the change by dual operational amplifier system control output voltage electric current, show electric current and voltage output state and size by digital display circuit, realized collection and the conversion of data and pass to single-chip computer control system making a decision processing by the inner ADC of single-chip computer control system again, realize the intelligence output and control of electric current and voltage by button; The dual operational amplifier system has formed a differential amplifier circuit by LM358 and non-essential resistance, because the electric current of charging chip KA7005B output is less, can't detect, so through the differential amplifier circuit amplified current, then through the single-chip computer control system collection, 10 by single-chip computer control system inside are approached capable ADC one by one, carry out obtaining digital signal after AD changes and show at digital display circuit at last; Single-chip computer control system is selected ATMEGA16 for use, the gatherer process of major control data, and with the data that collect by analysis processes and displays on digital display circuit, output pwm signal again on the other hand, control DC/DC conversion chip.
The beneficial effects of the utility model are: utilize new forms of energy solar energy; green, safe, renewable; take full advantage of the intelligent of monolithic processor control device simultaneously; be provided with complete electric current and voltage and detect protective circuit, and by digital display circuit display circuit state, can select circuit output flexibly by function key; can be as the charge power supply of different electronic products; use flexibly, be convenient for carrying, simple to operate.
