请参阅图1,按照图示参数搭建电路,电源VCC电压为24V,正常情况下,输出端Vo电压为12V,假设由于某种原因输出端Vo的输出电压突然增大,则三极管VT3基极电位也增大,使VT3的Vbe增大,VT3的Ib增大,VT3发射极电位升高,VT2的Vbe减小,VT2的基极电流减小,VT2的集电极电流也减小,VT1的集电极电流也减小,VT1的管压降Vce增大,从而维持输出端Vo电压保持不变;如果输出端Vo的输出电压突然减小,情况与上述类似,在此不在描述;电阻R1、电容C3和二极管D1组成RCD钳位电路,在电源VCC电压波动较弱的情况下,能增强电路的稳定性,电容C2的作用是利用其充电电流,提升三极管VT2和VT3的开关速度。Please refer to Figure 1 to build the circuit according to the parameters shown in the figure. The VCC voltage of the power supply is 24V. Under normal circumstances, the voltage of the output terminal Vo is 12V. If the output voltage of the output terminal Vo suddenly increases for some reason, the base potential of the triode VT3 Also increases, so that the Vbe of VT3 increases, the Ib of VT3 increases, the emitter potential of VT3 increases, the Vbe of VT2 decreases, the base current of VT2 decreases, the collector current of VT2 also decreases, and the collector current of VT1 The electrode current also decreases, and the tube voltage drop Vce of VT1 increases, thereby maintaining the voltage at the output terminal Vo unchanged; if the output voltage at the output terminal Vo suddenly decreases, the situation is similar to the above, and will not be described here; resistor R1, capacitor C3 and diode D1 form an RCD clamping circuit, which can enhance the stability of the circuit when the VCC voltage fluctuation of the power supply is weak.
