一、概述在光点注入式火控系统中,计算机输出的诸元,是通过微光阴极管进行显示。供微光阴极射线管的高压电源质量好坏,直接影响微光阴极射线管的光点质量,它对高压电源的稳定度,可靠性均提出较高的要求,目前我国生产中小功率的高压稳压电源不多见。我们在上海无线电一厂生产的 YTB—12陶瓷电源变换器的基础上,经过适当改制,作为微光阴极射线管的 First, an overview In the spot-injection fire control system, the computer output of the elements, through the dim light cathode tube display. The quality of the high-voltage power supply for the glimmer cathode ray tube directly affects the spot quality of the glimmer cathode ray tube. It puts forward higher requirements on the stability and reliability of the high-voltage power supply. At present, Power supply rare. Based on the YTB-12 ceramic power converter produced by Shanghai No.1 Radio Factory, we have adapted it as a low-light cathode ray tube
