Accompanying drawing explanation
Fig. 1 is the circuit diagram of computer stabilized-voltage power supply controller.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of computer stabilized-voltage power supply controller，Including resistance R1、Diode VD1、Audion VT1、Potentiometer RP1、Audion VT2 and electric capacity C1，Described resistance R1 one end connects power supply VCC respectively、Diode VD1 negative pole、Resistance R3、Audion VT2 colelctor electrode and audion VT1 colelctor electrode，The resistance R1 other end connects diode VD2 negative pole and potentiometer RP1 one end respectively，Potentiometer RP1 slide plate connecting triode VT5 base stage，Audion VT5 emitter stage connecting triode VT4 emitter stage，Audion VT4 colelctor electrode connecting triode VT2 base stage and audion VT3 colelctor electrode respectively，Audion VT3 base stage connects diode VD1 positive pole and resistance R2 respectively，Audion VT3 emitter stage connects the resistance R3 other end，Described audion VT2 emitter stage connecting triode VT1 base stage，Described audion VT4 base stage connects electric capacity C1 respectively、Resistance R4、Electric capacity C2、Audion VT1 emitter stage and output end vo，The electric capacity C2 other end connects the resistance R4 other end respectively、The electric capacity C1 other end、Audion VT5 colelctor electrode、The potentiometer RP1 other end、The resistance R2 other end and diode VD2 positive pole；Described diode VD1 and diode VD2 is Zener diode.
Operation principle of the present utility model is: refer to Fig. 1, VD1, R2, R3 and VT3 collectively constitute a constant-current source circuit, thering is provided electric current for adjusting pipe (VT1 Yu VT2 multiple tube) and prover pipe VT4, adjust R3 and the value of other elements, making constant-current source electric current is 2.5mA.R1, RP1 and VD2 form continuously adjustabe constant pressure source, provide reference voltage for VT5 base stage, and R1 is current-limiting resistance.
When making power supply VCC voltage rise due to outside cause, VT4 base voltage rises equally, supplies by constant-current source because of electric current I4 and I2 again, so I2 reduces, the Ube causing VT1 increases, and forces input power VCC voltage to decline, has reached the purpose of stable output end vo voltage；When power supply VCC voltage declines, voltage stabilizing process is contrary with said process.
