Analysis of the low frequency response of automatic balancing D-C amplifier with mechanical chopper is illustrated by a typical circuit in this paper. The analysis of dynamic response of the modulation and the demodulation circuits and the auxiliary carrier wave amplifier have been considered more in details.

本文結合一个典型线路对带有机械振子的自动稳零直流放大器的低頻特性,进行了分析,并且着重分析了調制解調輔助放大器对緩变信号的频率响应。所用方法是差分方程求解法,因为用差分方程来描述具有机械振子的調制解調线路的固有工作过程,要比用相同的初始条件的微分方程来描述更为准确。文中推导出調制及解調綫路的調制系数k_M、解調系数k_(ДM)以及它們的传递函数。此外,对放大調制波的阻容耦合放大器也进行了分析。分析結果說明,如果放大器耦合迴路的参数选择得合理吋,則此放大器对緩变信号的調制波可作为理想放大器来处理。文中所得結果可作为設計該类型放大器时选择参数的参考。此外,本文对于采用自动稳零直流放大器作运算放大器时可能产生的持續低頻自激振蕩問題,也进行了討論。

在电力线路上使用的载波频带中,除带滤波器式宽频带阻波器中电感的分布电容必须加以考虑,在设计时,L_1的分布电容可以并入并联的电容C_1中,而表示L_2的分布电容的自然谐振频率f0成为设计参数之一。为了保证在给定截止频率f2′和f_1′范围内输入阻抗大于KR,采用了和f2′与f1′稍有差别的设计用的截止频率f2和f1,按照f2和f1进行设计,就可使在f2′和f1′时的输入阻抗电阻部分等于R。f2—f1比f2′—f1大些。这两个频率可以从给定的f2′、f1′、f0′和电感电容的功率因数中求出。f0一般可以采用在1.5f2′和2f2′间的数值为宜,大于2f2′的f0会使扼阻频带中的颠值阻抗降抵,小于1.5f2′f的f0会使扼阻频带外的输入阻抗降低得太快。末端电阻KR中的K以采用1和0.95间的数值为宜,如果K小于0.95,扼阻频率带中的最低阻抗KR变得太小;如果K大于1,在给定的f2′—f1′情况下所需频宽f2 f1变得大些,这就提高强流线圈的电感L_1,使所需采用的有色金属多些。

This paper describes a detailed analysis of conversion properties of junction transistors. A new parameter "the effective conversion transconductance" is introduced for characterizing transistor converters. The effective conversion transcon-ductance of transistor converters using a PNP transistor operated at different oscillatory conditions and at various signal frequencies are studied. Main differences between transistor converters and vacuum tube converters are compared.
