Abstract

Brazilian National Synchrotron Light Laboratory (LNLS) has commissioned its 500-MeV booster synchrotron machine. In this paper we present an overview of the magnet power supply system comprised by precise (better than 10 ppm) current supplies ranging from 5 A to 300 A, with powers of a few watts to 126 kW, and current ripple of 0.02 to 0.1% relative to the maximum current. As the booster operates also as a storage ring, a special ramped current power supply had to be designed for the dipole magnets in order to accomplish both requirements of fast ramping up (1.9 s) and precise DC operation
