微波管剧烈打火不一定都是管子本身的问题。对于设计不佳的线型调制器,在微波管偶然打火后,人工线充电电压增高,因而输出电压增高,导致微波管接连不断地打火。在调制器负载短路时,有效的线型调制器削波电路应使充电电压限制在给定值。传统的设计方法不能予计可能产生的电压增量。本文分析了削波电路对充电过程的影响,导出了由削波电路参数决定的非线性方程组,给出了利用计算机求解的方法、源程序和计算结果。应根据微波管不进入不稳定区所允许的过电压值,利用本文的结果来设计完善的削波电路。
Violent tube lighting is not necessarily the problem of the tube itself. For a poorly designed linear modulator, the artificial line charging voltage increases after the microwave tube accidentally ignites, thus increasing the output voltage, causing the microwave tube to fire one after another. When the modulator load is short-circuited, an effective linear modulator clipping circuit should limit the charge voltage to a given value. Traditional design methods do not account for possible voltage increments. This paper analyzes the influence of the clipping circuit on the charging process, derives the nonlinear equations determined by the parameters of the clipping circuit, and gives the method, the source program and the calculation results by computer. According to the microwave tube does not enter the unstable area of the allowed over-voltage value, the results of this paper to design a perfect clipping circuit.
