Its injection chain includes fast-cycling superconducting synchrotrons booster and Nuclotron. The report shows the features of the construction of power converters and protection devices feeding groups of superconducting magnets working with second cycles of field formation. The power systems of the magnets of the Nuclotron, Booster and collider NICA are shown. The work of the regulators to obtain the required current accuracy in the entire dynamic range is reflected. Experimental data on the operation of the Nuclotron and Booster power systems are presented. A promising model of a power supply system with a superconducting inductive storage is shown.}}, }
