Abstract :
Goals for Advanced Photon Source reliability and orbit stability make it important to quickly identify and replace individual converters that may glitch or have relatively noisy output. The many converters involved and the limitations of the standard EPICS control interface makes it difficult to detect these converters. This paper presents our approach for quantifying noise and identifying glitches in individual converters. Implementation of the algorithms in the local power supply controller is addressed with concern for resource limitations such as bandwidth, sampling rate, and processing power
