Abstract

The B-Factory is a high-energy physics facility for studying matter versus anti-matter asymmetry. It utilizes 200 Intermediate DC power systems, employing 2.5 to 17kW switchmode converters, to supply beam-shaping magnets with regulated current. Redundancy and modularity were considered to maximize reliability and minimize mean time to replace (MTTR), within technical limitations and cost constraints. Described are the configurations that were considered and reliability prediction models. The SLAC decision to employ a single converter was sound. However, 2 years of operation have confirmed that converter reliability must be improved
