A kind of operation principle of solar charger for mobile phone that utilizes of the present invention is as follows:
First triode VT1 pole pipe is Switching Power Supply pipe, and it and transformer T, the first resistance R1, the 3rd resistance R3, the second electric capacity C2 etc. form self-excited oscillation circuit.After adding the voltage that solar panel A produces, electric current flows to the base stage of the first triode VT1 through the first resistance R1, makes the first triode VT1 conducting.
After first triode VT1 conducting, the first windings of transformer T just have input direct voltage, its collector current increases at the first winding center lines, the second windings of transformer T produce 3 positive 4 negative induced voltages, make the first triode VT1 obtain base stage to be just, to launch very negative positive feedback voltage, this voltage injects base current through the second electric capacity C2, the 3rd resistance R3 to the first triode VT1 makes the electric current of the collector electrode of the first triode VT1 increase further, positive feedback produces avalanche process, makes the first triode VT1 saturation conduction.During the first triode VT1 saturation conduction, transformer T stores magnetic energy.Meanwhile, induced voltage charges to the second electric capacity C2, along with increasing of the second electric capacity C2 charging voltage, the base potential step-down gradually of the first triode VT1, when the first triode VT1 base current change can not meet its continue saturated time, the first triode VT1 exits saturation region and enters amplification region.
After first triode VT1 enters magnifying state, its collector current is declined by the maximum before magnifying state, 3 negative 4 positive induced voltages are produced in the second windings, the base current of the first triode VT1 is reduced, its collector current reduces thereupon, there is avalanche process in positive feedback, the first triode VT1 ends rapidly again.After first triode VT1 ends, the energy that transformer T stores is supplied to load, and the 5 negative 6 positive voltages that secondary winding produces, after the first diode D1 rectifying and wave-filtering, the 3rd electric capacity C3 obtain direct voltage to charging mobile phone battery.
5th resistance R5, the 6th resistance R6, the second diode D2, the second triode VT2 etc. form pressure limiting circuit, to protect battery not by overcharge.In the charging process of battery, cell voltage rises gradually, when charging voltage is greater than certain value, after the 5th resistance R5, the 6th resistance R6 dividing potential drop, the second diode D2 starts conducting, make the second triode VT2 conducting, the shunting action of the second triode VT2 reduces the base current of the first triode VT1, thus reduces the collector current of the first triode VT1, reaches the effect of restriction output voltage.
