Abstract :
Approximately 1000 individual X-Y corrector magnets will be installed on the PEP-II rings, arcs, and injector lines. Each magnet will require a bi-polar current of up to 12 A, with a 24 hour stability of better than 0.1%. A 16 channel, modular power supply design has been developed to meet this requirement, with emphasis placed on reliability, repair time, and installed cost per channel. This design, which is based on a 6U Eurocard crate architecture, has 16 slots for individual drive modules, plus a 17th slot for crate diagnostics and interface to the control system. The crate is air cooled. Each drive module consists of an H-Bridge MOSFET switching array, input and output filter networks, two isolated precision current sensing elements (feedback and monitor), and an error amplifier, plus extensive fault detection and current limiting circuitry. Technical specifications, diagrams, and test results are presented
