Purpose, Goal and Intended Audience June 21 – July 2, 2004 Section 1. Purpose, Goal and Intended Audience 3 Purpose • Provide an overview (review) of Accelerator Power Conversion Engineering Goal • Provide a historical overview of Accelerator Power Supplies from early designs, to presently employed technology, to some promising future developments now in incubation • Give other, non-power conversion disciplines a glimpse of, and a better understanding of, Power Conversion Engineering • Survey the most pertinent power supply topologies from the perspectives of load type and rating • Define the information needed for the power supply designer to make appropriate choices for power supply type, design and rating • Identify the factors that affect power supply output stability, regulation, and reliability. To summarize the state-of-the-art in some of these areas June 21 – July 2, 2004 Section 1. Purpose, Goal and Intended Audience 4 Intended Audience • Civil, Mechanical Designers – interest in facility space, mounting, cooling • Control Designers – an insight into some interface requirements June 21 – July 2, 2004 Section 1. Purpose, Goal and Intended Audience 5 Intended Audience • Electrical Distribution System Designers – AC distribution requirements, address and reduce harmonics and EMI • Maintenance Personnel – power system reliability and maintainability • Magnet Designers – tradeoffs between power supply output voltage, current and stability limitations and the magnet design. The power supply role in magnet protection via cooling interlocks and ground fault detection and protection June 21 – July 2, 2004 Section 1. Purpose, Goal and Intended Audience 6 Intended Audience • Operators – Power supply control and operating characteristics • Physicists – Power system rating limitations, magnet configuration options vs. physics tradeoffs, long and short-term current stability limitations June 21 – July 2, 2004 Section 1. Purpose, Goal and Intended Audience 7 Intended Audience • Power Conversion / Power Supply Designers – power systems from another point of view • Project Engineers and Managers – Power conversion system costs • Safety Engineers / Designers – Personnel and equipment safety in an electrical power environment.
