    Magnet power supplies are critical components of a storage ring. The performance of power supplies directly impacts the stability and reliability of the storage ring operation. There are several type of DC power supplies in Duke FEL storage ring. The performance data of power supplies can be collected in a non-interruptive manner by an EPICS archiver or by a MATLAB program. MATLAB based tools have been developed to analyze the power supply data collected during the operation. Careful evaluation of data allows us to identify a power supply with degraded performance and provide a reference to perform preventive maintenance.
