Magnet Power Supply System for the SRF “SKIF” Storage Ring

The power supply system of the magnets of the injection complex of the SRF “SKIF” includes about 70 DC sources, 3 pulse current generators, and about 100 AC sources. DC sources include five types of precision bipolar and unipolar sources with a maximum output current from 3 to 300 A and a maximum output voltage of 24 V. The maximum output current of pulse generators is from 1.5 to 10 kA, voltage up to 1 kV. AC sources include four types of sources with a maximum output current from 6 to 900 A and a maximum reactive power of 0.5 MW. For reliable operation of the injection complex, it is necessary to ensure the stability of the parameters of the current sources, high reliability of operation, and the fast replacement of failed current sources the sources of the same type. All these current sources have been developed and produced by the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences.
