Abstract
The invention discloses a handset DC electronic charger circuit, composed of signal generator, power amplifier, output voltage control, filter, etc. It can realize: its power supply part uses two AAA dry cells, and its charging efficiency reaches about 70%; it can limit maximum safety voltage, and when current is larger than 200Ma, its output voltage is stabilized at the voltage about 1V higher than that of the charged cell, and thus it ensures the safety of handset and cell plate.
Description
1. technical field
The present invention is a kind of mobile phone DC electronic charger circuit, belongs to the electrical charger technical field.
2. background technology
Existing mobile phone DC electronic charger generally is to obtain 4.5V, 6V voltage in modes such as dry cell serial connections, then directly to cell-phone charging.The rated voltage of battery plate of mobile phone is generally 3.6V～4.2V, and under the direct situation to cell-phone charging of 4.5V voltage (three joint 1.5V dry cell serial connections), its charge efficiency is no more than 30%, and promptly the utilance of battery is very low; Though directly can improve charge efficiency to cell-phone charging with 6V voltage, the volume of charger will increase, and be not easy to carry; In addition, if when the rated voltage of battery plate of mobile phone is the 2.4V left and right sides, with 6V voltage directly charging can cause mobile phone or circuit board damage.
3. summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, a kind of charge efficiency height is provided, can guarantees the mobile phone DC electronic charger circuit of mobile phone and cell panel safe charging.
Technical scheme of the present invention is that mobile phone DC electronic charger circuit is made up of five parts such as dry cell, signal generator, power amplifier, output voltage controller, filters.Described signal generator is made of reverser ICA, resistance R 1, capacitor C 1, reverser ICB, resistance R 2, reverser ICC, resistance etc.; Described power amplifier is made up of pliotron N1, N2, energy-storage travelling wave tube inductance L 1, L2, diode D1, D2 etc.; Described output voltage controller is made of voltage-stabiliser tube WD1, resistance R 4, triode N3, N4 etc.;
Described filter is made up of capacitor C2, C3 and inductance L 3 etc.
The present invention has used the inductive energy storage principle, has effectively promoted output voltage, and the energy partly uses two joint AAA dry cells, and the utilance of battery can reach about 70%; Used voltage controller at the circuit output, can limit the highest safe voltage, and had when output current＞200mA, output voltage stabilization is being higher than the voltage that is recharged about battery 1V.

Fig. 1 is an electrical principles block diagram of the present invention;
Fig. 2 is circuit theory diagrams of the present invention.
5. specific embodiment
As shown in Figure 1 and Figure 2, the present invention partly is made up of dry cell 1, signal generator 2, power amplifier 3, output voltage controller 4, filter 5 etc.It is that signal source is sent continuous impulse that described signal generator 2 constitutes multivibrator by reverser ICA, resistance R 1, capacitor C 1, by reverser ICB shaping, reverser ICB output connects resistance R 2, reverser ICC input, resistance R 2 other ends are as one tunnel output signal, reverser ICB output connects resistance R 3, resistance R 3 other ends are as the second tunnel output signal, and the phase difference of two paths of signals is 180 °, are sent to power amplifier 3; Two paths of signals difference driving power triode N1, N2 by signal generator 2 is sent here are located at T1 temporal power triode N1 conducting, and in T2 temporal power triode N2 conducting, electric current arrives ground by inductance L 1, pliotron N1 when pliotron N1 conducting; T2 temporal power triode N1 ends, and in the moment that pliotron N1 ends, energy-storage travelling wave tube inductance L 1 will be kept its sense of current, because pliotron N1 ends, electric current just arrives ground by diode D1, filter 5 and load (being mobile phone and cell panel); Electric current ends to ground T1 temporal power triode N2 by inductance L 2, pliotron N2 when pliotron N2 conducting, in the moment that pliotron N2 ends, energy-storage travelling wave tube inductance L 2 will be kept its sense of current, because pliotron N2 ends, electric current is just by diode D2, filter 5 with load to ground.The load that so goes round and begins again just can constantly obtain electric current.
As shown in Figure 1 and Figure 2, described output voltage controller 4 is made of voltage-stabiliser tube WD1, resistance R 4, triode N3, N4 etc., when output voltage WD1 conducting during greater than the puncture voltage of voltage-stabiliser tube WD1, triode N3, N4 base voltage raise and conducting triode N3, N4 grounded emitter; Because the collector electrode of triode N3, N4 connects the base stage of triode N1, N2 respectively, when triode N3, N4 conducting, triode N1, N2 base voltage ≈ 0.3V, triode N1, N2 are ended, power amplifier quits work, and output loop stops electric current output, and voltage is descended; When voltage dropped to certain value, voltage-stabiliser tube WD1 ended, and triode N2, N3 end, and triode N1, N2 resume work, and so repeated control output voltage.Described filter 5 is made up of capacitor C2, C3 and inductance L 3 etc.
