关于《抹浆机电路小改进及其分析》的第一篇文章,分析与解决了稳压电路电阻过热烧毁和电源变压器发烫冒烟的问题(参考本刊1981年第三期第13页)。本续篇将分析与解决稳压电路输出不能稳定在12伏的问题。让我们对稳压部分的输出电压V_0作一定量分析。稳压部分电路如图。从图中可知,比较放大器BG_5基极电位 On the first article of “Small Improvement and Analysis of Wiper Pulverizer”, the problem of overheating resistance of power supply and overheat of the voltage regulator circuit and the problem of extinction of smoke from the power transformer was analyzed and solved (for reference, Issue 3, 1981, p. 13) . This sequel will analyze and solve the problem that the output of a regulated circuit can not be stabilized at 12 volts. Let’s make a certain amount of analysis on the output voltage V_0 of the regulated part. Regulator part of the circuit as shown. It can be seen from the figure, compare amplifier BG_5 base potential
