Abstract

Awareness of the impact of component-level radiation response on the system is challenging. This article discusses the radiation response of a power supply system by combining the power converters’ radiation effects and the dynamic Bayesian network (DBN) model. The total ionizing dose (TID) effects, displacement damage (DD) effects, and single event effects (SEEs) of the power converters are studied by conducting Co-

-ray, protons, and heavy ion tests, respectively. Then, the possible fault propagation models in the power supply system are analyzed, and a DBN structure is constructed based on these models. The variations of each part in the power supply system during the mission time are predicted. Finally, the DBN model is verified through the irradiation test results of the power supply system.

组件级辐射效应对系统性能影响的动态贝叶斯网络建模

意识到组件级辐射响应对系统的影响是具有挑战性的。本文将电源变换器的辐射效应与动态贝叶斯网络（DBN）模型相结合，讨论了供电系统的辐射响应。分别通过Co- $60~ $ γ -射线、质子和重离子试验，研究了功率转换器的总电离剂量（TID）效应、位移损伤（DD）效应和单事件效应（SEEs）。然后，分析了供电系统中可能存在的故障传播模型，并基于这些模型构建了DBN结构。对任务期间供电系统各部分的变化进行了预测。最后，通过供电系统的辐照试验结果对DBN模型进行了验证。

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
