For example, the fault of the magnet power supply front-end electronics devices may cause accelerator energy instability and even lead to beam loss. Therefore, it is very necessary to diagnose and locate the device fault accurately and rapidly, that will induce the high cost of the accelerator operation. Faults diagnosis and prediction can not only improve the safety and reliability of the equipment, but also effectively reduce the equipment’s cycle costing. We applied the FMECA and testability modeling method for the PSI device, which using in BEPCII power supply control system, and evaluated the remaining life of the PSI under certain temperature and humidity condition based on the reliability model and accelerated life test.
