Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of intelligent adjustable stabilized voltage supply, comprises transformer T, rectifier bridge Q, resistance R1, electric capacity C1, triode VT1, potentiometer RP1 and diode D1, described transformer T primary coil two ends connect 220V alternating current two ends respectively, and transformer T secondary coil two ends connect rectifier bridge Q pin 1 and rectifier bridge Q pin 3, rectifier bridge Q pin 2 contact resistance R1 respectively respectively, electric capacity C1, electric capacity C4 and resistance R2, the resistance R1 other end connects the electric capacity C4 other end and diode D2 negative pole respectively, diode D2 positive pole connecting triode VT1 collector electrode, and triode VT1 base stage is the contact resistance R2 other end respectively, electric capacity C2 and triode VT2 collector electrode, triode VT2 emitter is contact resistance R3 and diode D1 negative pole respectively, and the resistance R3 other end is connecting triode VT1 emitter respectively, potentiometer RP1 one end, electric capacity C3 and output end vo, potentiometer RP1 slide plate connecting triode VT2 base stage, the potentiometer RP1 other end connects the electric capacity C3 other end respectively, diode D1 positive pole, the electric capacity C2 other end, the electric capacity C1 other end and rectifier bridge Q pin 4 also ground connection, described diode D2 is voltage stabilizing didoe.
Operation principle of the present utility model is: refer to Fig. 1, and through Q rectification, electric capacity C1 filtering, obtains direct current, be transported to voltage stabilization part, and voltage stabilization part is made up of the silicon diode VD1 etc. of Correctional tube VT1, amplifier tube VT2 and a pressure stabilization function.
Tube voltage drop on Correctional tube VT1 is variable, and when output end vo voltage has the trend of reduction, VT1 tube voltage drop can automatically diminish, maintain output end vo voltage constant, when output end vo voltage has the trend of increase, VT1 tube voltage drop can automatically become large again, still maintains output end vo voltage constant.Visible, VT1 is equivalent to a variable resistor, due to its corrective action, output end vo voltage is remained unchanged substantially.
The corrective action of Correctional tube VT1 controls by amplifier tube VT2, output end vo voltage is through potentiometer RP1 dividing potential drop, a part for output voltage is added between the base stage of VT2 and ground, because the emitter voltage to earth of VT2 is stable by D1, can think that the emitter voltage to earth of VT2 is constant, this voltage is called reference voltage, like this, the change of VT2 base voltage just reflects the change of output voltage rhythm, if output end vo voltage has reduction (to refer to absolute value, lower same) trend, voltage between VT2 Base-Emitter also will reduce, this just makes the collector current of VT2 reduce, collector voltage increases, because VT2 and VT1 is direct-coupled, VT2 collector voltage increases, voltage namely between VT1 Base-Emitter increases, this just makes VT1 add heavily conducting, tube voltage drop reduces, maintain output end vo voltage constant, equally, if output voltage has the trend of increase, by the effect of VT2, the tube voltage drop of VT1 is increased, maintain output voltage constant.
C2 considers when line voltage reduces, in order to the alternating component reducing output voltage is arranged; R1, C4 and D2 form a clamp circuit, can carry out clamper, play certain corrective action to the fluctuation of input voltage, improve the stability of system at power input to voltage.
