Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figure 1:The present invention includes silicon photocell VG, the first capacitance C1 to the 3rd capacitance C3, first resistor R1 to the Six resistance R6, the first triode VT1, the second triode VT2, diode VD, voltage-stabiliser tube DW, three-winding transformer T and calculator The cathode output end of accumulator E, silicon photocell VG simultaneously with the first end of the first capacitance C1, the first end of first resistor R1, the The first end of two resistance R2 is connected with the first end of the first winding NP of transformer T primary, and the cathode of silicon photocell VG is simultaneously with the The second end of one capacitance C1, the emitter of the second triode VT2, the 4th resistance R4 first end, the second triode VT2 transmitting Pole, the cathode of voltage-stabiliser tube DW, first end, the first end and the 6th resistance of the 5th resistance R5 of the second winding NB of transformer T primary The first end connection of R6, the second end of first resistor R1 while base stage, the first end of 3rd resistor R3 with the first triode VT1 It is connected with the collector of the second triode VT2, the second end collector with the first triode VT1 and the change simultaneously of second resistance R2 The second end connection of the first winding NP of depressor T primary, the second end of 3rd resistor R3 are connected with the first end of the second capacitance C2, the The second end of two capacitance C2 is connected with the second end of the second winding NB of transformer T primary, the base stage of the second triode VT2 simultaneously with The second end of 4th resistance R4 is connected with the anode of voltage-stabiliser tube DW, and the first end of transformer T secondary windings NS is with diode VD's Anode connects, the second end of transformer T secondary windings NS while second end, the first end of the 3rd capacitance C3 with the 6th resistance R6 Connected with the cathode of calculator accumulator E, the anode of calculator accumulator E simultaneously with the second end of the 3rd capacitance C3, the 5th electricity The second end of resistance R5 is connected with the anode of diode VD.
The operation principle of the present invention is as follows:
Circuit of the present invention is single tube DC transfer circuit, using the form of single-end flyback converters circuit.When the one or three When pole pipe VT1 is turned on, the induced voltage of transformer T primary coils NP is negative for 1 positive 2, and secondary coil NS is 5 positive 6 negative, diode VD In cut-off state, at this moment transformer T passes through primary coil NP and stores energy;When the first triode VT1 ends, secondary coil For 5 minus 6 just, the energy stored in transformer T passes through diode VD rectifications and the backward load output of the 3rd capacitance C3 filtering to NS.
First triode VT1 is Switching Power Supply pipe, it and transformer T, first resistor R1,3rd resistor R3, the second capacitance C2 etc. forms self-excited oscillation circuit.In addition after input power, the activated resistance first resistor R1 of electric current flows to the first triode The base stage of VT1 turns on the first triode VT1.
After first triode VT1 conductings, transformer T primary coils NP is just plus input direct voltage, collector current The linear increase in NP, feedback coil NB generate 3 positive 4 negative induced voltages, and the first triode VT1 is made to obtain base stage just, to send out Emitter-base bandgap grading is negative positive and negative feedthrough voltage, this voltage injects base current through the second capacitance C2,3rd resistor R3 to the first triode VT1 The collector current of the first triode VT1 is made further to increase, positive feedback generates avalanche process, makes the first triode VT1 saturations Conducting.During the first triode VT1 saturation conductions, transformer T stores magnetic energy by primary coil NP.
At the same time, induced voltage gives the second capacitance C2 to charge, with increasing for the second capacitance C2 charging voltages, the one or three Pole pipe VT1 base potentials are gradually lower, when the base current variation of the first triode VT1, which cannot meet it, continues saturation, the One triode VT1 exits saturation region and enters amplification region.
After first triode VT1 enters magnifying state, collector current is declined by the maximum before magnifying state, anti- Feeder line circle NB generates 3 minus 4 positive induced voltages, reduces the first triode VT1 base currents, and collector current subtracts therewith Small, there is avalanche process again in positive feedback, and the first triode VT1 ends rapidly.
After first triode VT1 cut-offs, the energy of transformer T storages is supplied to load, and the 5 minus 6 of secondary coil NS generations Positive voltage obtains DC voltage to charging mobile phone battery after diode VD rectifying and wave-filterings on the 3rd capacitance C3.
When the first triode VT1 ends, 3 minus 4 positive voltages of the defeated people's voltage of direct current supply and NB sensings are again through first Resistance R1, the 3rd capacitance R3 give the second capacitance C2 reverse chargings, gradually step up the first triode VT1 base potentials, make it again Conducting, again overturning reach saturation state, and circuit repeats vibration and goes down like this.
5th resistance R5, the 6th resistance R6, voltage-stabiliser tube DW, second triode VT2 etc. form pressure limiting circuit, to protect battery It is not overcharged, here by taking 3.6V batteries as an example, the limitation voltage that charges is 4.2V.In the charging process of battery, battery electricity Pressure is gradually increasing, and when charging voltage is more than 4.2V, voltage-stabiliser tube DW starts to lead after the 5th resistance R5, the 6th resistance R6 partial pressure It is logical, the second triode VT2 is turned on, the shunting function of the second triode VT2 reduces the base current of the first triode VT1, So as to reduce the collector current of the first triode VT1, have the function that limit output voltage.At this moment circuit stopped pair The voltage of battery is maintained 4.2V by the large current charge of battery with low current.
Basic principle of the invention and main feature and advantages of the present invention has been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its Equivalent thereof.
