Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment
As shown in Figure 1, at first the input end plug on the laptop electric power adapter circuit is inserted on the 220V power supply, output terminal inserts on notebook computer, press pushbutton switch AN1,3,4 ends of the U circuit on the laptop electric power adapter circuit get electric work, 3,4 end output 19V DC voltage of U circuit provide voltage to notebook computer, give simultaneously the charging of the battery in notebook computer, make notebook computer start work.The DC voltage of 3 end outputs of U circuit is after the first resistance R 1 step-down simultaneously, output 12V voltage charges to the first capacitor C 1 through the 3rd resistance R 3 after voltage stabilizing diode VD1 voltage stabilizing, when the first capacitor C 1 is recharged, make the base voltage of the first triode Q1 lower than emitter voltage through the 4th resistance R 4, the first triode Q1 conducting, collector output high level makes the second triode Q2 conducting through the 5th resistance R 5, the 6th resistance R 6 dividing potential drops, the second triode Q2 conducting makes relay J 1 adhesive, switch J1-1 is closed, and 1 end of U circuit is kept and 220V power connection state.but after pushbutton switch AN1 disconnects, after the first capacitor C 1 is filled electricity, the base voltage of the first triode Q1 is higher than emitter voltage, the first triode Q1 cut-off, the collector of the first triode is without high level output, but the output terminal 4 end negative poles of U circuit are connected with the 3rd diode D3, the 3rd diode D3 the 7th resistance R 7 in parallel, after the computer normal boot-strap, the 3rd triode D3 two ends, the 7th resistance R 7 two ends will produce the voltage of 0.5-0.7V, make the 3rd triode Q3 conducting, after the 3rd triode Q3 conducting, the collector output low level makes the 4th triode Q4 conducting, on the 4th, the emitter of Q4 is connected on the proper voltage of U circuit output end 3 through the 3rd diode D4, at this moment, the collector output high level of the 4th triode Q4 is through the 8th resistance R 8, the 5th diode D5 connects the collector of the first triode Q1, make the collector of the first triode Q1 keep the output high level, make the second triode Q2 keep conducting, relay J 1 keeps adhesive, switch J1-1 remains closed, U circuit maintenance work.
After notebook electricity normal shutdown, as battery underfill electricity in notebook computer, power supply adaptor also will be given battery charging in notebook computer, the 3rd diode D3, the 7th resistance R 7 two ends still can produce the voltage of 0.5-0.7V, make the 3rd triode Q3, the 4th triode Q4 keep conducting, the second triode Q2 keeps conducting, and relay J 1 keeps attracting state, U circuit maintenance work.Along with after battery is filled electricity; the positive electrode current of the 3rd diode D3 is very little; can produce certain pressure drop at the 7th resistance R 7 both ends; the 3rd diode D3 is equivalent to by the 7th resistance R 7 short circuits; the 3rd diode D3 two ends can not produce the approximately voltage of 0.5 left and right, and the 3rd triode Q3, the 4th triode Q4 and the second triode Q2 all end, relay J 1 not adhesive; the U down circuitry, thus reach using electricity wisely and protection computer battery.
