Power Supplies of Correction Magnets of Modern Accelerating Complexes

The Budker Institute of Nuclear Physics has been designing two accelerator facilities of the Mega-Science class [1, 2]. It is planned to use the same bipolar power supplies sources for corrector magnets in both projects. These power supplies must provide an output current of 6 and 12 A and output voltage up to 100 V. Identical power-supply sources will be used both for slow orbit correction and for fast orbit feedback. As a result, the power-supply sources must provide the high stability of output current (at least 0.01%) and adequate bandwidth (at least 1k Hz). The project must allow for the fast replacement of a failed power-supply source.
