Problems solved by technology

[0003] The main conversion means of the secondary power supply of satellite electronic products is to use DC / DC to convert the primary and secondary power supplies. As a single-event sensitive device, it is easy to be affected by the space environment or load fluctuations during operation, causing a certain degree of fault. Some faults are recoverable to the DC / DC device itself, and some faults are unrecoverable. When the fault stress accumulates to To a certain extent, it will also cause the expansion of the fault
