Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, in the embodiment of the utility model, a kind of computer intelligent power controller comprises resistance R1, electric capacity C2, triode VT2, diode VD1, electric capacity C1 and diode VD2, and the collector electrode of described triode VT1 is respectively connected resistance R5, Transistor VT2 collector, power supply VCC and triode VT4 collector, triode VT1 base connected to triode VT2 emitter, triode VT2 base respectively connected to triode VT5 base, diode VD1 cathode, resistor R4 and triode VT4 collector, the other end of resistor R4 Connect the other end of the resistor R5 to the cathode of the diode VD2, the anode of the diode VD2 to the emitter of the triode VT1, the resistor R3, the resistor R1 and the output terminal Vo respectively, the other end of the resistor R1 to the base of the triode VT4 and the resistor R2 respectively, and the other ends of the resistor R2 respectively Connect capacitor C2, resistor R6, diode VD1 anode, capacitor C1, and resistor R7 to ground, and the other end of resistor R7 is connected to the other end of capacitor C1 and the emitter of transistor VT5, and the other end of resistor R6 is respectively connected to the emitter of transistor VT3 and the emitter of transistor VT4 , the base of the triode VT3 is respectively connected to the other end of the resistor R3 and the other end of the capacitor C2; the diodes VD1 and VD2 are both Zener diodes; the voltage of the power supply VCC is 24V.

The working principle of the utility model is: please refer to Fig. 1, when the output voltage increases due to the voltage change of the power supply VCC or the load change of the output terminal Vo, the voltage of the base of the triode VT4 to the ground is increased by the sampling circuit formed by R1 and R2, and The base of the triode VT3 is connected to the capacitor C2, and its voltage cannot change suddenly, then the collector current of the triode VT4 will increase in proportion to the difference between the sampling voltage and the reference voltage, so that the voltage drop on the resistor R4 connected to the collector of the triode VT4 UR4 increases.

UW2=UR4+Ube1+Ube2, where UW2 is the stable voltage of the regulator tube VD2, Ube1 and Ube2 are the voltage between the base and emitter of the transistor VT1 and the transistor VT2, because UW2 is stable, so when UR4 increases, Ube1+Ube2 decreases, and as a result, the collector current of the triode VT1 decreases, and the tube voltage drop Ube1 increases, which offsets the increase in the output voltage and keeps the voltage at the output terminal Vo unchanged.

In addition, the voltage signal sampled by the resistor R1 and the resistor R2 is also reflected to the base of the transistor VT5 through the transistor VT4, and the slight voltage fluctuation can be turned on by the transistor VT5 to keep the voltage of the output terminal Vo stable.
