As the satellite power supply and distribution functions and complexity are gradually strengthened, the reliability requirements of the aerospace secondary power supply are getting higher and higher. Based on the basic composition and working principle of aerospace secondary power supply, this paper analyzes the reliability of the fault tree analysis method (FTA), combs the weak link of the product, and proposes design improvement measures for the weak link.
