Background technology
Along with the fast development of global economy, the improving constantly of people's living standard, the electronic product kind of carried type is also more and more.Nowadays along with the variation day by day of digital product function, uses more frequent, related also more and more closer with people's daily life, improve the service time of digital product and at any time additional electric weight become businessman and consumer's questions of common interest.For solving the charging problem, portable power source arises at the historic moment.
Portable power source in the market mostly is fixed voltage and electric current, but because the diversity of digital product, different product required voltage and electric currents may be different, and the portable power source of fixed voltage, electric current just can in use be restricted at this moment.
Summary of the invention
Based on this, be necessary to provide the portable power source of a kind of variable voltage and electric current.
A kind of power supply comprises: interface, ammeter, voltmeter, slide rheostat, quantity is identical and a plurality of switches, a plurality of diode and a plurality of solar cell one to one,
Described voltmeter two ends are in parallel with the two ends of described interface, described ammeter one end connects an end of described interface, the other end connects an end of described slide rheostat, the other end of described slide rheostat connects second end of described a plurality of one of them switch of switch, this switch first end connects second end of another switch, and described a plurality of switches are connected successively;
The negative pole of described a plurality of diodes connects first end of corresponding described switch respectively, and the positive pole of described a plurality of diodes connects the positive pole of corresponding described solar cell respectively;
The negative pole of described solar cell all connects the other end of described interface simultaneously.
Among one of them embodiment, described switch, described diode and described solar cell are six.
Above-mentioned power supply can be adjusted output voltage and electric current according to different needs quickly and easily, and simple in structure, and volume is less, is easy to carry.
