Brief description of the drawings
Fig. 1 is the circuit diagram of the energy-saving control circuit suitable for computer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of energy-saving control circuit suitable for computer, including electric capacity
C1, resistance R1, triode VT1, amplifier U1, electric capacity C2 and resistance R2, described electric capacity C1 one end connect input V1, and electric capacity C1 is another
One end connects resistance R1, resistance R2 and resistance R5 respectively, and the resistance R1 other ends connect amplifier U1 end of oppisite phase and resistance R3 respectively, electricity
The resistance R3 other ends connect electric capacity C2 and amplifier U1 output ends, electric capacity C2 other ends connection output end vo, amplifier U1 in-phase ends respectively
The connection resistance R2 other ends and resistance R4, the resistance R4 other end connecting triode VT1 colelctor electrode triode VT1 emitter stage divide respectively
Not Lian Jie resistance R6 and electric capacity C3, electric capacity C3 other ends connection resistance R6 is simultaneously grounded, and triode VT1 base stages connection resistance R5 is another
End；The amplifier U1 uses LM324.The control signal V1 can be high level and low level.The electric capacity C1 and electric capacity C2
For capacitance.The triode VT1 is NPN triode.
Referring to Fig. 1, circuit is built as illustrated, when input V1 is logical one state（2.4V~4V）, triode
VT1 saturation conductions, R4 is grounded, and chooses R1=R2=R3=R4, then the input end signals of amplifier U1 two are equal, therefore amplifier output end
Signal is approximately zero, and now amplifier U1 is in holding state, and energy consumption is low.
When input V1 is logical zero state（Ground potential）, triode VT1 ends, at amplifier U1 in-phase input end
In earth-free state, i.e. amplifier U1 be in difference-mode input state, amplifier U1 output end normal output signals, now amplifier U1 be in
Working condition.
When being in cut-off state due to triode VT1, amplifier U1 inputs have DC level, and cause output also to have direct current
Level, therefore add C1, C2 capacitance in input, output end.
In summary, the energy-saving control circuit that the utility model is applied to computer is only needed when not needing amplifier work
It is logical zero state to want control signal V1, you can amplifier U1 is in holding state, energy consumption is low, good energy saving property.
