中巴资源卫星上的星内粒子辐射探测器的探头必须要工作在稳定,高信噪比的直流高压电源下。事实证明,安装在中巴资源1和中巴资源2卫星上的探测器高压单元能够保证整个探测器的正常运行。但是,新的实验对高压单元的设计提出了新的要求和新的技术指标,作者根据要求和技术指标对原来的探测器高压单元部分进行了改进。首先简要介绍粒子辐射探测器以及它在空间探测方面的作用,然后介绍探测器高压单元的基本原理,并对其中的振荡换能部分进行理论分析和数值模拟。通过数值模拟,可以从理论上预言高压单元工作点的稳定性以及输出电压随其他参数波动式的变化。最后,对所做的模拟进行相关的讨论和展望。
The probe of the intracamera particle radiation detector on the CMBS satellite must work under a stable, high S / N DC high voltage power supply. It has been proved that the detector high-voltage unit installed on CMB 1 and CMB 2 satellites can ensure the normal operation of the entire detector. However, the new experiments put forward new requirements and new technical specifications for the design of high-voltage units. The author improved the original high-voltage unit of detectors according to the requirements and technical specifications. Firstly, the particle radiation detector and its role in space exploration are briefly introduced. Then the basic principle of the detector high pressure unit is introduced, and the theoretical analysis and numerical simulation of the oscillation transduction part are carried out. Through numerical simulation, the stability of the working point of the high voltage unit and the fluctuation of the output voltage with other parameters can be theoretically predicted. Finally, the simulation and the related discussions and prospects.
