Abstract: According to the high safety requirement of aerospace power supply and the difficulty of potential fault risk prediction, a device that can predict the potential fault of an aerospace power supply is developed. The potential fault of the power supply can be judged by the method of simulating the change of load and simulating the change of input voltage, and detecting the output voltage, current and power adjustment rate of the power supply. And the two methods have been verified by experiments. The results show that the fault detection methods and devices designed for aerospace power supply can predict and judge the potential fault of the aerospace power supply.
