Protection domain within.
The utility model proposes a kind of electric supply installation.
As it is shown in figure 1, in one embodiment, above-mentioned electric supply installation includes battery 30, charges and be for controlling battery 30
Charging/the supply modules 10 of load 40 power supply, cut with the power supply that charging/supply module 10 is load supplying for switching battery 30
Die change block 20；Wherein, charging/supply module 10 include booster circuit the 100, first audion Q1, the second audion Q2, the one or two
Pole pipe D1, the second diode D2, voltage stabilizing adjust pipe U, the first resistance R1, the second resistance R2, the 3rd resistance R3 and charging resistor RS；
The input of booster circuit 100 is connected with the outfan VI of DC source, the first outfan of booster circuit 100 and the one or three pole
The colelctor electrode of pipe Q1 connects, the second outfan of booster circuit 100, first end of the first resistance R1 and the collection of the second audion Q2
Electrode interconnection；The emitter stage of the first audion Q1 is connected with the first end of charging resistor RS, and it connects node for power supply/switching mould
The power supply outfan of block 10；The base stage of the first audion Q1 is connected with the colelctor electrode of the second audion Q2, the of the first resistance R1
The anode interconnection of two ends, the base stage of the second audion Q2, the anode of the first diode D1 and the second diode D2；First diode
The first end interconnection of the negative electrode of D1, the second end of charging resistor RS and the second resistance R2, it connects node is power supply/handover module
The charging outfan of 10；The negative electrode of the second diode D2 and voltage stabilizing adjust the negative electrode of pipe U and are connected, the reference pole of voltage stabilizing adjustment pipe U,
Second end of the second resistance R2 and the first end interconnection of the 3rd resistance R3, voltage stabilizing adjusts the of the anode of pipe U and the 3rd resistance R3
Two end ground connection GND.
When the outfan VI of above-mentioned DC source has DC source to export, direct current power source voltage is entered by booster circuit 100
Row boosting processes and exports the first voltage at its first outfan, exports the second voltage at its second outfan.Wherein, the first electricity
Pressure is main output voltage, for charging to battery 30 and loading 40 power supplies；Second voltage is auxiliary output voltage, for for follow-up
Circuit provides and drives electric current.Usually, the value of the second voltage is higher than the value of the first voltage.
The compound Darlington formula structure of first audion Q1 and the second triode Q2 composition, for being amplified driving electric current
Process, to improve the current gain of charging/supply module 10 output.When battery 30 is in charged state, due to battery 30 electricity
Pressure ratio is relatively low, and voltage stabilizing adjusts pipe U and is not turned on, the first audion Q1, the second audion Q2, the first diode D1 and charging resistor RS
Constitute constant current output circuit.Now, it is assumed that the pressure drop between base stage and the emitter stage of the first audion Q1 is VBE1, the two or three pole
Pressure drop between base stage and the emitter stage of pipe Q2 is VBE2, and the pressure drop between anode and the negative electrode of the first diode D1 is VD1, fills
The pressure drop at electricity resistance RS two ends is VX, then have VD1-VX=VBE1+VBE2 according to circuit ultimate principle.Because the first audion Q1
Base stage and emitter stage between pressure drop, pressure drop between the second audion Q2 base stage and emitter stage and the first diode D1
Pressure drop constant between anode and negative electrode.So, the pressure drop constant at charging resistor RS two ends, the electric current flowing through charging resistor RS is permanent
Fixed.So, charging/supply module 10 is achieved that the constant-current charge to battery 30.
It is understood that the supply voltage that charging/supply module 10 gives load 40 is battery 30 voltage and charging resistor
RS both end voltage sum, owing to when being configured the parameter of circuit, the value of charging resistor RS is smaller, so that

Logical, the first audion Q1, the second audion Q2, charging resistor RS and the first diode D1 form constant current loop.When battery 30 fills
When electricity completes, battery 30 voltage raises, and voltage stabilizing adjusts pipe U conducting, and the second diode D2 shunting flowed through the first diode D1 originally
Driving electric current so that the first diode D1 ends because two ends pressure drop is too low, and the electric current flowing through charging resistor RS is reduced to zero.
It is to say, when battery 30 is in charged state, the first diode D1 conducting, the second diode D2 by；When battery 30 fills
When electricity completes, the first diode D1 cut-off, the second diode D2 conducting.Now, by the first diode D1 and/or the second diode
D2 is set to light emitting diode, may indicate that battery 30 whether charging complete.Such as, if the first diode D1 is bright, then electricity is described
Pond 30 is in charged state, if the second diode D2 is bright, then and explanation battery 30 charging complete.
In view of the custom of most users, the first the most above-mentioned diode D1 is red light emitting diodes, the two or two pole
Pipe D2 is green LED.Especially, when the glow color of the first diode D1 and the second diode D2 is identical, permissible
The diverse location arranged by light emitting diode judges that battery 30 is in charged state the most charging complete.
