Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be readily apparent from
Solve, below in conjunction with being specifically illustrating, the present invention is expanded on further.
As it is shown in figure 1, a kind of 5V power supply adaptor intelligent control circuit, first L1 and N1 end is connected to
On 220V power supply, click press button AN1, L1 end iodine salt and be coupled to U circuit 2 through U circuit internal circuit
Foot, punctures bilateral diode BT2 output AC voltage through resistance R2, through press button AN1, through resistance R1
It is connected to 2 feet of bidirectional triode thyristor BT1, triggers the conducting of BT1 bidirectional triode thyristor, make U circuit 1 foot and 2 feet obtain
Electricity work, the voltage comparator that 4 foot output 5V voltage one tunnels of U circuit are connected to IC2LM393 composition is integrated
8 feet power, a road is connected to the positive pole of D3 diode, and the negative pole of D3 diode is connected to Q4 audion
Emitter stage, 5V voltage charges through R12 resistance box electric capacity C1 simultaneously, while C1 electric capacity charges, makes Q4 tri-
Pole pipe conducting, Q4 transistor collector output high level makes Q1 triode ON through R10 resistance, makes IC1 light
Coupling obtains electric work.IC1 optocoupler internal illumination pipe obtains electroluminescence, makes the internal photosensitive resistance of optocoupler become very
Little, now AN1 press button disconnects, and the alternating voltage of BT2 bilateral diode output is protected through photoconductive resistance
Holding voltage to export 2 feet of BT1 bidirectional triode thyristor and make bidirectional triode thyristor tend to remain on, U circuit keeps leading
Logical state.
The 5V voltage of now U circuit output is when there being load to connect, during as charged the phone, at R8 resistance
Upper end, 6 feet of IC2 voltage comparator LM393 produce the voltage of about 0.1V-0.5V, because of R3 resistance one end even
Receiving one end of 5V voltage, the other end is connected to 3 feet and 1 foot of VT1TL432 regulator block, electricity after voltage stabilizing
Pressing tongs position, at 1.4V, connects 5 feet of IC2 voltage comparator after R6 resistance and R7 electric resistance partial pressure, makes IC2 electricity
5 feet of pressure comparator are fixed on 0.6V, and now 7 foot output high level of IC2 voltage comparator make Q3 audion
By, Q4 audion by, now the 1.4V voltage after VT1 voltage stabilizing also divides through R4 resistance and R5 resistance
Be connected to 2 feet of IC2 voltage comparator after pressure, make 2 foot voltage clamps of IC2 voltage comparator at 0.08V,
And now 5V voltage has charged to mobile phone, because 3 feet and 6 feet of IC2 voltage comparator link together, now
5V voltage is while mobile phone charges, at the other end of R8 resistance, 3 feet of IC2 voltage comparator and 6 feet
Produce the voltage of about 0.1V-0.5V, make 3 foot voltages of IC2 voltage comparator higher than 2 foot voltages, IC2 voltage
1 foot output high level of comparator makes Q1 audion be held on through R10 resistance after D1 diode current flow,
Making IC1 optocoupler be held on, BT1 bidirectional triode thyristor is held on, U circuit holding work, and mobile phone keeps filling
Electricity.
Along with C1 electric capacity is quickly fully charged, Q1 audion is made to export low electricity by, Q1 transistor collector
Flat, and now still keep exporting high level because of 1 foot of IC2 voltage comparator, make Q1 audion be held on,
U normal circuit operation.After mobile phone is fully charged, 3 feet and 6 feet at IC2 voltage comparator produce the least
Voltage drop, the most only 0.05V voltage, make 3 foot voltages of IC2 voltage comparator be less than 2 foot voltage 0.08V,
1 foot output low level, make Q1 audion by, IC1 optocoupler dead electricity does not works, BT1 bidirectional triode thyristor by,
U down circuitry does not works, reach mobile phone fully charged after, automatically disconnect 5V power supply adaptor power supply, economize on
Electricity, prevents battery of mobile phone from overcharging, and reaches extending cell phone battery.
When the electronic equipment such as mobile phone or panel computer is because of some reason, charging inlet can produce loose contact and
The phenomenons such as leak electricity short-circuit, the most such as continue charging, and charging inlet can make charging because of electric leakage and indirect short circuit
Mouth electric current is excessive, produces heating, can produce fire or battery and produce the danger such as blast because of short circuit thermal.This
Time when current is excessive, at 3 feet of IC2 voltage comparator and 6 feet by generation higher than nominal charging voltage, just
The voltage that often R8 resistance produces is about 0.1-0.5V, when being loaded with short circuit, as long as voltage is more than 0.7V
Time, now 6 foot voltages of IC2 voltage comparator be higher than 5 foot fixed voltage 0.6V, 7 foot output low levels,
Make Q1 triode ON, make Q2 triode ON, Q2 transistor collector output low level, make Q1 tri-pole
Pipe base stage is in low level, Q1 audion by, IC1 optocoupler dead electricity does not works, and BT1 bidirectional triode thyristor cuts
Extremely, make U circuit dead electricity not work, reach, when output loading 5V electric leakage and short circuit, to automatically power off, reach
Safety utilization of electric power, it is to avoid the problem caused danger because of load electric leakage and short circuit.
On the ultimate principle of the present invention and principal character and advantages of the present invention have been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, above-described embodiment and description
Described in the principle that the present invention is simply described, without departing from the spirit and scope of the present invention, this
Invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention
