Description of drawings
Accompanying drawing is the circuit diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing; The power input Ui of the utility model is connected with the output (not shown) of solar panel; Comprise the first triode VT1, first resistance R 1, the 3rd resistance R 3, second capacitor C 2, high frequency transformer T1, the first diode VD1, the 3rd capacitor C 3; The two ends of first resistance R 1 are connected with the positive pole of power input Ui and the base stage of the first triode VT1 respectively; One end of the 3rd resistance R 3 is connected with the base stage of the first triode VT1; The other end of the 3rd resistance R 3 is connected with the negative pole of power input Ui with the feedback coil Nb series connection back of C2 second electric capacity, high frequency transformer T1 successively; The emitter of the first triode VT1 is connected with the negative pole of power input Ui, is connected with the positive pole of power input Ui behind the primary coil Np of the collector electrode of first triode VT1 series connection high frequency transformer T1, and the end of the secondary coil Ns of high frequency transformer T1 is connected and is connected with the positive pole of output Uo behind the first diode VD1; The other end of the secondary coil Ns of high frequency transformer T1 is connected with the negative pole of output Uo, and the 3rd capacitor C 3 is connected in parallel between the positive pole and negative pole of output Uo.
Shown in accompanying drawing; The utility model also comprises the second triode VT2, the second diode VD2, the 5th resistance R 5 and the 6th resistance R 6; The collector electrode of the second triode VT2 is connected with the base stage of the first triode VT1; The emitter of the second triode VT2 is connected with the negative pole of power input Ui, and the 5th resistance R 5 and the 6th resistance R 6 series connection back are parallelly connected with the 3rd capacitor C 3, and the base stage of the second triode VT2 is connected and is connected between the 5th resistance R 5 and the 6th resistance R 6 behind the second diode VD2.Be connected with the 4th resistance R 4 between the negative pole of the base stage of the second triode VD2 and power input Ui; The two ends of the primary coil Np of high frequency transformer T1 are connected in parallel to second resistance R 2.
Shown in accompanying drawing, triode VT1 is the Switching Power Supply pipe, and it forms self-excited oscillation circuit with T1, R1, R3, C2 etc.After adding the input power supply, electric current makes the VT1 conducting through the base stage that starting resistance R1 flows to VT1.After the VT1 conducting, transformer Np just adds input direct voltage, and its collector current Ic increases at the Np neutral line; Feedback coil Nb produces 3 positive 4 negative induced voltages; Make VT1 obtain base stage for just, launch very negative positive feedback voltage, this voltage injects base current through C2, R3 to VT1 further increases the collector current of VT1; Positive feedback produces avalanche process, makes the VT1 saturation conduction.During the VT1 saturation conduction, T1 stores magnetic energy through primary coil Np.Meanwhile, induced voltage charges to C2, and along with increasing of C2 charging voltage, the VT1 base potential is step-down gradually, can not satisfy it and continues when saturated when the base current of VT1 changes, and VT1 withdraws from the saturation region and gets into the amplification region.After VT1 got into magnifying state, the maximum of its collector current before by magnifying state descended, and produced 3 negative 4 positive induced voltages at feedback coil Nb; The VT1 base current is reduced; Its collector current reduces thereupon, and avalanche process appears in positive feedback again, and VT1 ends rapidly.After VT1 ended, transformer T1 energy stored offered load, and the 5 negative 6 positive voltages that secondary coil Ns produces obtain direct voltage and give charging mobile phone battery behind diode VD1 rectifying and wave-filtering on C3.When VT1 ended, 3 negative 4 positive voltages of defeated people's voltage of direct current supply and Nb induction were given the C2 reverse charging through R1, R3 again, improve the VT1 base potential gradually, make its conducting again, and the state that reaches capacity that overturns once more, circuit repeat to vibrate like this.R5, R6, VD2, VT2 etc. form pressure limiting circuit, do not overcharged with the protection battery, and be example with the 3.6V battery of mobile phone here, its charging deboost is 4.2V.In the charging process of battery; Cell voltage rises gradually, and when charging voltage during greater than 4.2V, voltage stabilizing didoe VD2 begins conducting after R5, R6 dividing potential drop; Make the VT2 conducting; The shunting action of VT2 has reduced the base current of VT1, thereby has reduced the collector current Ic of VT1, has reached the effect of restriction output voltage.At this moment circuit has stopped the large current charge to battery, with little electric current the voltage of battery is maintained 4.2V.
