摘要
为了评估某电源系统抗伽玛总剂量辐射能力,研究了评估电子系统抗伽玛总剂量辐射能力的QMU方法。为获得应用QMU方法所需的输入量,提出了以蒙特卡罗方法和SPICE电路模拟相结合的分析方法,用以确定受伽玛辐照后系统性能参数的裕量及不确定度。应用QMU方法对电源系统抗伽玛总剂量能力进行了评估,将评估结果和实验结果进行了比较,验证了方法的可行性。
The quantification of margins and uncertainties(QMU) method is analyzed,which is used to assess the radiation hardness of the electronic system.In order to use the QMU method,a procedure based on Monte Carlo method and SPICE circuit simulator is proposed to evaluate the margin and uncertainty of the system's output.The radiation hardness of a power supply system is assessed,and the assessed results are in good agreement with those obtained experimentally.
