Study on Total Dose Test Method and Damage of Typical Satellite Electronic Equipment

Total dose level of electronic equipment is one of the important factors effecting the reliability of satellite in orbit. It is of great significance to know the weak link of radiation resistance of electronic equipment in advance. In this paper, the Solar Array Controller (SAC) is used to find the system weak links of radiation resistance, from two aspects of theory analysis and experiment validation, and the test results can provide reference for the effective anti-radiation reinforcement during the design of the circuit system. Finally, the analysis method of radiation resistance of electronic equipment system is summarized.
