Problems solved by technology

As the aerospace mission system becomes more and more complex, the number of electrical equipment is increasing, the power is increasing, and the reliability requirements of the power supply system are becoming higher and higher. The traditional electromechanical power distribution system can no longer meet the system distribution requirements. The current development trend is to adopt power supply and distribution technology based on solid-state power controllers

[0003] In the traditional power distribution system, the power distribution control of electrical equipment is mainly completed through relays, overload protectors, etc., but often due to the failure of these power distribution components or a certain electrical load, the electrical equipment cannot work normally, and cannot Obtaining system fault information through telemetry or other means makes it difficult to diagnose and repair the system

Only to determine the fault point often requires a very complicated manual testing process, which is time-consuming and laborious
