Particle accelerators use a great variety of power converters for energizing
their sub-systems; while the total number of power converters usually depends
on the size of the accelerator or combination of accelerators (including the
experimental setup), the characteristics of power converters depend on their
loads and on the particle physics requirements: this paper aims to provide an
overview of the magnet power converters in use in several facilities worldwide.Comment: 30 pages, contribution to the 2014 CAS - CERN Accelerator School:
